DWOS 3.0 user guide STI75-‐0028 1-‐7 2 General overview 2.1 Starting scanners and the DWOS software To begin, turn on the 7Series, 5Series or 3Series scanner using the power switch on rear panel. The symbol “O” is off and “__” is on. Next: • For the 7 or 3Series scanner, boot the embedded computer by pressing the center green”√” button located on the front panel scanner • For the 5Series scanner boot the external PC Next, log onto the PC using “DWOS” for the account id and “dwos” for the password. Once logged in, you will be at the general Dental Wings screen as shown below. The DWOS Prostheses design software is based on client/server architecture. Thus, to bring up the system you will always need to first start the server and then start the client. To do: 1. Double click on the DWServer icon to start the server. A window will appear during the launch, when completed a server icon will appear in the taskbar near the clock) 2. Double click on the DWClient icon to start the client showing the login window asking for username and password. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 2-‐1 By default, the username “adm” is enabled with the password “adm”. After logging in, you should see the main client window as shown below. System initiation and the login procedure is now completed. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 2-‐2 2.2 Order identification and process: scan, cad, production To use the DWOS, everything is associated to a unique order number. Generation of this order number is the first of four main steps most commonly used in the system. The four main steps are: •
•
•
•
Create an order Scan a physical model or an impression (except on 3Series) to create 3D digital model Generation of the prosthesis design using DWOS prostheses design software Initiation of an intended Production choice: in-‐house or out sourced The unique order number is used by the DWOS modules to manage the case through the entire process. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 2-‐3 2.3 Basic user interface principles 2.3.1 Software general concept The DWOS prostheses design software is mainly icon driven. The main horizontal icon bar as shown below, is always displayed and it allows you to run the main DWOS applications, such as: order creation, arch scan, CAD design, etc. The left bar below is displayed within the scan application and these bars are displayed as needed. The icons are context sensitive and when displayed as gray as shown with the right bar below, this indicates that they are inactive and cannot be used within the current context. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 2-‐4 The main DWOS window is always divided into three mains areas. 1. Orders list 2. Main application area 3. Order summary You can change the respective size of each area by moving the separation bars. The order list is organized by columns. You can invert the sort order by a double left click on the column name. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 2-‐5 The organization of columns can be changed by a right click in column header. You can remove columns You can change the columns order by dragging columns The new organization can be saved Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 2-‐6 The order summary is organized by tabs and you can switch between them by selecting either tab. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 2-‐7 2.3.2 Mouse handling & view manipulation The DWOS prostheses design software requires a mouse with two buttons and a wheel. The mouse interaction operates as follows: • Left click: menu, icon selection, point definition • Right click: definition validation, access to local menu • Rotate the wheel: zooms in/out • Press and hold the wheel while dragging the mouse: translates the view • Press and hold the right button while dragging the mouse: view is rotated • Press and hold the CTRL key while rotating the wheel: generates a cross section of the view • Double click left button: to center and resize the view • Double click the right button: to switch between perspective and parallel Projection Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 2-‐8 2.3.3 Display management 2.3.3.1 View type, clip plane, slice views The DWOS prostheses design software displays in full 3D so that you can get a complete view of the clinical situation and prosthesis under design. You can use the View Type menu in the view toolbar at the bottom right of the screen to switch between predefined view orientations. You can use Clips Planes in the view toolbar to generate a cross sectional view that is perpendicular to the selected axis. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 2-‐9 Example of cross section in the mesial axis is shown below. You can use the wheel to move the cross section. When using Clips Planes, you can display a measuring grid by selecting Clip Grid in the view toolbar. The grid provides the User with a User definable reference grid (default is 0.5 mm). To change the grid size over strike the numeric value (e.g. 0.5mm to 1.0mm) or simply drag the glide bar to increase or decrease the grid box sizes. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 2-‐10 When using Clips Planes, you can also use another measuring tool by selecting the Measure button in the view toolbar. Then click and hold the left mouse button to define the start point of the measure, while dragging the mouse to the desired end point. The measurement is dynamically displayed as the mouse is being dragged. The measure is made in the plane selected for the clip. To exit from Clips Planes, select Unclip in the Clip Planes menu. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 2-‐11 2.3.3.2 Display buttons Using the Display buttons at the top center of the main application area, you can display or to hide parts of the clinical situation and/or prostheses. The list of Display buttons changes according to the DWOS application and the clinical situations as they are context sensitive. Each Display button toggles as follows: • An up blue arrow: displays the part • A down red arrow: hides the part Hide/show clinical situation Hide/show undercut (scan application) Hide/show friction (scan application) Hide/show antagonists Hide/show anatomies Hide/show prostheses (including connectors) Hide/show connectors Hide/show wax-‐up Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 2-‐12 2.3.3.3 Transparency button The Transparency button at the top the main area will allow you to adjust the degree of transparency of the component parts of the clinical situation and/or prostheses. To adjust, use the glide bars as shown below. 2.3.3.4 Virtual Articulator Feature Prior to using this feature, it is required that the User manually articulate the desired case, using the SAM articulator with magnets attached to both the upper and lower stone model aches. Once the User is satisfied with the articulation, the User must carefully take each arch with the attached magent, being careful to not move its position within the holder. Upon completion of scanning both components, the DWOS will then propose the requested design respecting the dynamic articulation. To view the dynamic articulation, select the Virtual Articulator feature from within the CAD design function using the following icon: When selected, the following pull down menu is displayed: The parameters from the pull down can be modified for analysis for the individual case using the tabs as shown above. The two white and green play buttons will show the dynamic movements of the case. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 2-‐13 2.3.4 Local menus During the scan and design processes, you will have to do specific tasks (e.g. editing the margin line, adjusting contact points, etc.…) on particular clinical elements. These tasks will be done using specific local menus that are context sensitive. For example, the local menu of a stump allows the edit of its margin, while the local menu of prosthesis will allow adjustment of its contact points. To access these menus, place the cursor of the mouse over the pertinent clinical element and press the right button of the mouse. The header of the local menu displays the tooth number. 2.3.5 Assistant The DWOS Prostheses design software includes software assistants that will guide you through a procedure. For example, during the scan process, assistants will prompt you through the scanning process. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 2-‐14 2.4 Units All dimensions, such as, size, thickness, distances, etc. are interpreted in millimeters. All measured angles are provided in degrees. 2.5 Parameter settings The DWOS Prostheses design software allows you to set the clinical parameters for the intended prosthesis designs, such as, material, type of prosthesis, thickness of coping, etc. These parameters are accessible through assistants. These parameters can be adjusted at different levels. 2.5.1 Local adjustment All parameters can be adjusted during the design of a given prosthesis. You can decide if the adjustment should be applied only for the current design or for all designs during your current CAD session by using the button. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 2-‐15 2.5.2 General adjustment The default parameters can also be adjusted for all the cases produced within your lab. To modify the defaults, please refer to the Material Management module (refer to chapter 9.4) for further details. 2.5.3 Customized parameters The parameters can also be adjusted for each dentist by using the Dentist Preferences module as shown below. For further details, please refer to chapter 9.6. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 2-‐16 2.6 Hot to exit from DWOS software and shutdown There are two methods to exit from the DWOS software. The first is you can click on the red quit icon within the main toolbar as shown below. The second method is to use the close button (“x”)within the upper right corner of the main window: With both methods, confirmation of your intention to quit the session is required. To confirm, select the yes button as shown: Once confirmed, the exit request closes the DWOS client application on the current computer. If you are running a multi-‐station configuration, repeat the exit procedure on all PCs to completely shutdown the Dental Wings application. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 2-‐17 Next, the DOWS server must be shut down. To do, left click on the server icon in the taskbar near the clock: Then select the Quit option in the following menu. Now the PC is ready to shutdown using the Windows shutdown procedure or by pressing the red shutdown button with the red “X” located upon the front panel of the 7Series or the 3Series scanner as shown: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 2-‐18 3 Order management 3.1 Dentist, Patient & order management: how to create, delete, edit The DWOS prosthesis design software provides a default Lab, Dentist and Patient for your convenience. To begin using the system, it is recommended that you define at minimum a new Dentist and when a new order is opened, a new patient can conveniently be entered for a given Dentist. The following section describes the procedures for entering a new dentist, patient and opening a new order. However, we begin with a brief overview of the relationship of these three components. The DWOS Prostheses design software manages data using three levels architecture which is easy to use and is linked automatically: • dentist • patient • order A patient is linked to a dentist and an order is linked to a patient. A patient and order cannot exist without these links. A dentist can be organized by country and clinic. An order can contain several prostheses designs. For example, within the same model you may produce a single design on tooth 12 and a three unit bridge design with teeth 15-‐16-‐17, all within the same order. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 3-‐1 3.1.1 How to Create a new order To create a new order, select the Order Receiving Application icon within the main toolbar as shown below. The main window of Order Receiving Application will then appear: Next click on the New sale order icon Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 3-‐2 The Select dental customer window will appear. Note that an automatic order number is generated with the following format: COM-‐yymmdd-‐order number of the day Where “yy” is the year, “mm” is the month and “dd” is the day, followed by an increased number for each case opened that day to keep each order number unique. Optional: The order number can be change by over striking the number within the field below. Optional: The default “COM” prefix can also be changed. To do, right click on the root level (in the above example, it is “My Laboratory”. Then select “Edit Info”, followed by selecting the “Identification” tab that will appear at the top of your screen. Next ,type within the “Unique ID” field what you would like to see as a default. Complete the procedure by selecting the “OK” button. This will now replace the “COM” with what you have entered, followed by the remaining yymmdd-‐order number format. Keep in mind that an order number has to be unique and that DWOS software will use it to manage the full CAD/CAM process of your case. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 3-‐3 Next select the dentist and patient in the lists and press OK If it is a new patient, press New button in the Patient List (or if available, select from the existing patient list): The Patient creation window appears. Enter the patient’s first and last name and press OK: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 3-‐4 To define a new dentist, press mouse right button on the customers, country or clinic level to access to local menu. Then select New Dentist The Dentist creation window appears. Enter all the necessary data and press OK: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 3-‐5 Once the Dentist and Patient are defined, you can create a new order and the order creation window appears. The DWOS Prostheses design software requires the following four definitions: • tooth number • material • type of prosthesis • single or bridged unit Define the tooth number by left clicking on the tooth. The tooth will then display as a representation of the selected type of prosthesis. If re-‐selected, using the right mouse button, the tool selection is canceled. The defined teeth will display convert to the Prosthesis type that is actively displayed. To define a different prosthesis type, first change the active type that’s displayed to the desired type, then select the desired tooth. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 3-‐6 Note: the American numbering system can be set within the “Manage Users” pull down menu located within the “Applications” icon. The anatomy that will be used can also be changed during the CAD design. Details on each tooth definition are displayed on the right within the “Framework Layer” tab and displayed as a list: To create a bridge, select all the desired teeth with a single left click on each tooth included within the bridge. A green lasso is created around each active tooth intended for the bridge. Then select the Create Bridge button and a gray lasso is generated grouping the entire bridge. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 3-‐7 Press Route Order button to complete the order. Then answer Yes to the prompt to route forward the order: The new order creation procedure is now completed. Note: if your order contains several order items, defined within the same order using the same procedure: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 3-‐8 3.1.2 How to edit and/or delete Dentist and/or Patient You can change or delete data associated to a dentist and a patient using the following procedure.

DWOS 3.0 user guide STI75-‐0028 3-‐10 3.2 Routing forward and back, starting the Scan & CAD applications The DWOS Prostheses design software provides tools to manage the progression of the order through the full CAD/CAM process. The software manages several operational steps after an order is created. • Scan: order is ready to be scanned automatically after an order is created • CAD engine: once order is scanned, the data is ready to be processed by the CAD engine to automatically generate a proposed prosthesis • CAD Design: proposal of the prosthesis is ready to be checked and customized • Production: completed prosthesis design is validated and ready to be produced either internally or electronically sub-‐contracted The change from one operational step to another is referred to as to “Route”. When routing a case, it can be routed in two directions: • route forward: usual production process from one step to the next (e.g. from Scan to CAD) • route back: from the given step to the previous. This is most commonly used to check for potential design adjustments (e.g. routing from Production to CAD completion to potentially modify the anatomy) The DWOS Prostheses design software automatically manages operational steps and Routes Forward. You can manually Route an order forward or back. To do, please refer to the next chapter. To start a scan, multi-‐die, import scan file, CAD engine or the CAD design application, press the appropriate icon within the main tool bar as shown below: Scan application CAD engine Multi-‐die application CAD design application Scan import application The DWOS Prostheses design software automatically starts the selected application and displays the main window of that application.

DWOS 3.0 user guide STI75-‐0028 3-‐15 4 Scanning 4.1 Introduction 4.1.1 Scanable material, coating The 7Series, 5Series and 3Series scanners are designed to scan plaster, silicone or alginates. As the 7Series, 5Series and 3Series are optical scanners, the quality of the scan is affected by shiny or translucent surfaces. These problems are easily resolved by utilizing a light coating to opaque the scan surface. Spray scanner coatings are commercially available. Ask your Dental Wings Distributor for a local recommendation. To avoid inferior scans, Dental Wings recommends operating scanners with doors closed. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐1 4.1.2 Scan Options: Multi-‐die and Standard with or without Antagonist The 7Series, 5Series and 3Series scanners allow different scan options. Select the best scan option according to the clinical case. They include: • Multi-‐die: several single dies are scanned in parallel (up to 30 with the 7Series, up to 6 with 3Series.). • Standard plaster models : can scan both a full upper and lower arch or preparations and/or implants • Standard plaster models with a check-‐bite of the opposing. • Standard plaster models with the opposing positive model. • Vertex hinge-‐style articulator with preparation and opposing arches, using a patented axis-‐finder technique. The axis finder holder is packaged with the 7Series, an optional purchase with the 3Series and 5Series. • A scan jig which fits into an analog to identify an implants exact angle and location. • A wax-‐up for replication. • Scanning an impression with the 7Series and 5Series, excluding the 3Series. • Full arch with palatal area to be utilized for partial framework design. Specific plaster model or impression holders are packaged with the 7Series, 5Series and 3Series scanners that are designed for each scan option. 4.1.3 Common processes with each type of scan Except for the Multi-‐die application, the scan options have very similar procedures with common basic steps: • Always start with scanning preparation arch • Initial scan preview reference scan • Definition of the area of interest • Identification of models location (typically via tooth numbers) • Precise scan of highest quality upon the elements (e.g. preps, scan jigs, palatal) with repositioning if needed • Automatic or manual margin line and cervical collar editing • Antagonist adjustment (if present) The Multi-‐die application combines both the Scan and CAD applications for single elements and is described in detail within chapter 6. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐2 4.2 For each scan option: A step-‐by-‐step Process 4.2.1 Standard holder 4.2.1.1 Installation of the model The standard holder is used to scan a full or partial arch or stone models. The standard holder allows several mechanical adjustments which include: • Model size with 3 choices of three positions (on 3Series scanner) for the two back screws and adjustable front grip. • Preparation axis with choice of platform angle. Adjustments can be made using the red hex tool that is provided with the scanner. Two releases of standard holder exist: one for 5Series scanner and one for 7Series, 5Series & 3Series scanner. 5Series first standard holder 7Series, 5Series & 3Series standard holder Install the model on the standard holder and place it inside the scanner. The fixing system is magnetic; ensure that the three holes of the holder are in front of the three balls of the scanner platform for the holder to properly seat. Then close the door. The scanners check if the door is closed before scanning. If not, the message “Close door” is displayed on the scanner’s front panel. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐3 Start the Scan Application and select the desired order (see chapter 3.2) Select Standard Holder within the Scan type list: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐4 4.2.1.2 Orientation and definition of area of interest A preview of a full or partial arch is displayed. Define the proper orientation of the model (if necessary) by placing the predefined blue area in the matching orientation with the scanned model. To do, first place the central green dot of the arch on the incisal edge at the mid-‐line (between the two centrals). Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐5 Using the forward and back arrow keys (<-‐ and -‐>) you can rotate 90° the predefined blue area. First, rotate the arch by placing the mouse on one of the buccal labels, Left Click and Hold, to move the green arch until it alignes with the central sulcus of the posteriors and the incisals of the anterior teeth. The arch will pivot around the Central Green Dot. Dental Wings inc.

DWOS 3.0 user guide STI75-‐0028 4-‐13 A confirmation is requested, select Start The die currently scanned is enclosed inside a red circle. This circle becomes yellow then blue during computation process. The software will automatically scan all the dies. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐14 4.2.1.7 Repositioning When all die scans using either the standard or multi-‐die holder are complete, the result of the 3D scan is displayed. You can see that the missing areas have been filled. The scan application includes a specific automatic module that repositions the dies scanned with respect to the global model. It is important to check if the results are OK for each die. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐15 To check, place the mouse over one die and right click to access to local menu, select Show/Hide Repositioning The result of the repositioning is displayed in red. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐16 A good repositioning is when the display of both red and gray are evenly intermixed in a marble like pattern. A bad repositioning is when large blocks of red are displayed. Examples of both are shown below: Bad positioning Good positioning When a bad repositioning occurs, you should reposition manually. To accomplish this, the scan application provides two methods to reposition: • Simple • Advanced Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐17 To start a simple repositioning, select Reposition Preparation in the local menu of the die. The scanned die is displayed in light blue outside the arch. The principle of simple repositioning is to define one point on the scanned die and to define the same corresponding point on the die inside the arch. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐18 Define the point on the scanned die by left clicking, and a red dot is displayed. Then define a corresponding second point on the arch by left clicking and a blue dot is displayed. The first and second points can be moved before validation. The die outside the arch can be rotated around red dot by keeping left button pressed while rolling the wheel. Note the order of definition. The red dot should be on the die outside the arch Validate with a right click or by pressing OK button. The repositioning is recomputed and then the completed result of the repositioning is displayed Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐19 If needed, an advanced repositioning can be done. To start an advanced repositioning, select Reposition Preparation (Advanced) in the local menu of the die. The scanned die is displayed in light blue outside the arch. The principle of an advanced repositioning is to define three points upon the scanned die within the “Reposition” window and corresponding three points upon the die within the “Reference” window. The resultant repositioning will display within the “Result Preview” panel (the lower half). Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐20 First define three points upon the scanned die within the “Reposition” panel with a left click and the positioned colored dots will display. Next, define the corresponding three points within the “Reference” panel with a left click and the positioned colored dots will display. The six points can be adjusted before validation if necessary. Once satisfied with placement, select the “Precise Repositioning” button to calculate. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐21 The repositioning is recomputed And the recalculated position is displayed: Verify the visual result is a marble like pattern with even bi-‐color distribution as shown above. When satisfied, validate and complete task by selecting the “OK” button (
). Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐22 4.2.1.8 Automatic Margin and Cervical Collar Line Generation and Automatic Insertion Axis Identification There are two methods for managing margin and collar lines. The DWOS can detect and define the margin and collar lines automatically or the End User can choose to define manually. In addition, the DWOS can identify the insertion axis automatically. There are two places that these calculations can occur: 1) within the “Arch Scan” application and 2) within the “Multi-‐die scan” application. This section will cover the arch scan application. Please refer to the “Multi-‐Die Scanning” of the User Guide for details about option two. Within the “Arch Scan” application, the margin and insertion axis of one or more dies can be automatically detected and identified. To do, select the “Edit Margin on Next Available Preparation” icon. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐23 Once selected the first or subsequent die that has completed a precise scan, will be displayed as shown. The default option is “Full Automatic Margin”. Accept this option by selection the “OK” button. The next panel is displayed. Make any adjusts (if necessary) by moving the green handles. The same margin is displayed within both the 3D and flat-‐wrap (bottom window) modes. When done, select the green check make to validate the margin. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐24 Next, the “Auto Insertion Axis” function is executed to auto-‐calculate a optimal axis of insertion. To do, select the “Auto insertion axis” button. Validate (accept) the calculated insertion axis by selecting the “OK” button. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐25 Next, the collar line is automatically calculated and displayed. The collar line will follow the contour of the margin per pre-‐defined distance as specified within corresponding material type definitions. The margin and collar lines can both be modified by utilizing respective edit icons. When satisfied with the margin and collar line, validate the case by selecting the “OK” button. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐26 When completed, both the margin line (green) and collar line (magenta) should both be displayed. Repeat procedure for subsequent dies by reselecting the “Edit Margin on Next Available Preparation” icon until all scanned preparations have the required margin and collar lines defined. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐27 When all preps have been completely defined, each preparations will have their respective margin and collar lines displayed as shown below. To complete the procedure, select the “Exit current design” button (blue) to complete the procedure. Then a prompt if you wish to route the case to the next procedural step is asked, select the “Yes” button to complete the editing and scanning procedure. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐28 4.2.1.9 Editing the Margin line and cervical collar To edit the margin line, select “Edit current margin design” option within the local menu of the die. You can optimize the automatic margin detection. To do, reposition the die to see the entire margin and block-‐out undercuts due to ditching, by moving the die within the 3D view. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐29 Once the entire margin can be seen, select the die’s corresponding ditching. Continue by pressing the “OK” button. The margin line edit function is separated into three views and one toolbar: • Main 3D view • Exploded view (flat wrap) is helpful to visualize the entire margin in one view • Slice view for fine checks and adjustments Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐30 The automatic detection prompts for a starting point to begin the margin detection. The mouse cursor is represented as a wand with a star at its end. Place the star on the margin and left click to define the margin starting point. An automatic proposal of the margin is then displayed. You can adjust the automatic margin proposal by moving points using the mouse. An active point is displayed in yellow and can be used to modify the margin’s location. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐31 You can add/remove points by simply double clicking between two points (to add) or single click on a point to remove. When a point is selected (i.e. displayed in yellow) DEL key deletes the next point in a clockwise direction. You can also use the arrow keys (left, right, up and down) to adjust points. The side view shows the cross section cutting through the model at the current point position to help to place the point on the margin’s edge (e.g. tangent point). While moving the handle position using the keyboard, you can move bigger steps pressing the SHIFT key while moving or move smaller steps by pressing the CTRL key.
Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐32 Left click on the green margin die icon to access the margin line editing parameters. By default, Project Margin on surface is selected. It means that margin will automatically follow the die surface. See the examples below: Initial projection. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐33 Move up & down the margin. Point stays on the die surface If Project Margin on Surface is not selected the margin will not follow the surface. See the same example below: Initial margin projection. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐34 Move up & down margin. Point is over or inside the die surface Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐35 You can move the entire margin at once or a portion of the margin by adjusting the gliding bar. On the far left it means the smallest item (i.e. moving a single point), on the far right it means the whole margin line is to be moved. When the bar is in between, you will move a relative section of the margin. The die can be displayed in Flat Shading mode, this could make margin adjustment easier. You can also display the undercuts (in red) by left clicking on the undercut icon. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐36 There are three methods to accept your margin design: • Right-‐clicking within the background • Pressing the <Enter > key • Clicking on the apply icon at the top right corner of the main view. If you want to exit the design mode without accepting the changes, then press the <Esc> escape key or clicking upon the cancel icon
at the top right corner of the main view. After the validation (acceptance) of the margin line design, you have to validate the parameters of the internal part of the prosthesis. The following window is displayed. The first Tab displays a 3D view that allows you to ask the system to calculate the insertion axis by selecting the “Auto Insertion axis” button. You can also choose a manual insertion axis for a die or bridge by repositioning the displayed model’s view for each active die. When the proper axis is defined, press the “Set Insertion Axis” button. Undercuts and the axis helper (red cylinder) can be displayed. Rotate the view until you can see all margins with minimal undercuts You can decide to have the same insertion axis for all elements of the model, which could include multiple dies and a bridge or to manage an axis individually for each die and a bridge. The Enforce 3-‐Axis Milling option will ensure that the same axis is used for a given bridge unit, but other individual die axis can still be individually managed by ensuring the same insertion axis for all elements is not selected. Same insertion axis applies on all the dies of the model, including dies within a bridge Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐37 There is a new Screenshot button which provides the ability to generate an image of the insertion axis view. After pressing this button, a .png image is created on the Desktop, the filename is displayed as shown below. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐38 Within the second Tab, the coping parameters are set: cement gap, minimum thickness, collar position, etc. By default, undercuts are automatically blocked-‐out. If you need to adjust Cutback margins, define its type using this list.(see below) The Emergence Angle works as follow: 0° leads to flat angle and 90° to sharp angle using the origin as a reference as shown below. 0° 65° The Emergence Angle given by the user will be used by the software as a guideline. That is, the software will apply control to guarantee marginal integrity and respect of the morphology. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐39 When a clinical pontic or reduced crown is selected, you have access to a third tab called Reduction Parameters. Within this tab you adjust the ceramic space between the ceramic interface (overlay) and the anatomical form. Cervical Reduction is only used for pontic cases.

You can adjust them as usual. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐101 4.2.7 How to Scan a Wax-‐up (7Series & 5Series only) The DWOS software includes the ability to scan a wax-‐up model and replicate what was scanned. This function can be of particular use if you have a wax-‐up that was generated by hand and the User would like to digitize it for options to manufacture digitally. To do, you will need the following components: the impression holder and the flat plate that attaches to the impression holder and the wax-‐up to scan. In addition, please insure the “Waxing Copy” option is checked, within the “Applications” button, “Material Management” Option, “Elements Available” pull down menu. The wax-‐up itself will need a sprue or similar small bar to fit into the impression holder and the small flat plate that comes with the impression holder. The tines of the fork on the holder and the plate will pinch shut upon the sprue so that it will not move during the scanning process. The process is as follows: Create an order and right click on units to describe each component (abutments if a bridge) as “Waxing Coping”. Note, if a bridge, do not define the pontics. In our example, we will use a bridge. Thus, the next step is to combine the defined abutments and undefined pontics into a grouping. To do, click on each abutment to activate, then right click and select the “Create a Bridge” option from the pull down menu as shown to the above right. Proceed as described in chapter 4.2.6 “5Series Impression Scanning” to install and launch the scan session as shown below: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐102 Next, define the orientation and area of interest and you will be prompted “Do you want to scan the waxing coping?” answer “OK” to begin the scan. Take note of the area of interest defined, because when prompted to scan the opposite side, you will need to select the opposite area of the arch. With the area define, start the precise scan of the upper side of the wax-‐up by selecting green check mark, followed by the “OK” button. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐103 When done, the User is prompted to rotate the impression arm of the holder so that the bottom side of the wax-‐up is pointing upward. If needed, the entire platform can be removed from the scanner to rotate the impression holder’s arm and reinsert within the scanner. When ready, select the “OK” button to continue scanning the underside. When prompted to define the area of interest, do not forget that you will be defining the opposite side of the arch since it is upside down. Also note, the User will be asked to define the tooth numbers from the underside of the wax-‐up (this is normal) and prompted with which resolution to scan. It is recommended the User select the “medium” resolution. A contour area circle with handles will display around each tooth scanned (if more than one). Adjust the contour area to include just the desired tooth by adjusting the handles to include each tooth (will need to repeat if multiple teeth are scanned). The completed scan of both sides of the wax-‐up will display as shown below: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐104 Next there are three more steps to do: 1. Remove the sprue from the scan by using the editing tools within the “Remove Scan Faces” option to cut, fill hole and smooth the area of connection accessed via the “Remove Scan Faces” option as shown below. 2. Right click on the model and select the “Export scan” option from the submenu and define the target destination for the output file(s). The second choice is #3. 3. Close the scan window by selecting the “Exit” blue button. You will be able to go into the “Applications” function, “Administrative Applications” submenu option and also find your completed design (even if you never exported within step #2). You would then “Retrieve manufacturing files” on the case as normal to generate output models. Dental Wings inc.

DWOS 3.0 user guide STI75-‐0028 4-‐106 4.2.8 How to Scan a Wax-‐up and Match to Scan Preparations (7Series & 5Series only) The DWOS software includes the ability to scan a wax-‐up model, scan the preparations a stone model and match the wax-‐up scan to the margins of the preparations of the stone model. This function can be of particular use if you have a wax-‐up that was generated by hand and the User would like to adapt it to a specific case. To do, you will need the following components: the model to scan with preps, the standard 5Series holder (for the model scan), the impression holder (for the wax-‐up scan) and the flat plat that attaches to the impression holder. The wax-‐up itself will need a sprue or similar small bar to fit into the impression holder and the small flat plate that comes with the impression holder. The tines of the fork on the holder and the plate will pinch shut upon the sprue so that it will not move during the scanning process. The process is as follows: Create an order and describe each component (abutments if a bridge) as “Simple Coping with Waxing”. Note, if a bridge, do not define the pontics. In our example, we will use a bridge. Thus, the next step is to combine the defined abutments and undefined pontics into a grouping. To do, click on each abutment to activate, then right click and select the “Create a Bridge” option from the pull down menu as shown to the above right. Proceed as described in chapter 4.2.1 “Scan with standard holder” to install the model and launch the scan session. On the arch scan parameters window, select: • Standard holder Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐107 Select the area of interest and assign the model tooth numbers as usual and described within chapter 4.2.1. However, precise scan of the individual dies is to be done later within this procedure. Once the arch scan has scanned the model, the wax-‐up will next be scanned using the following procedure. Select the “Start Waxing Top Preview Scan” icon as shown left. Install the wax-‐up onto the impression holder with the sprue being firmly held between the tines of the fork. Be sure to mount the occlusal surface facing upwards. When selecting the icon, the screen below is displayed: Define the orientation and area of interest as shown below: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐108 Then start the precise scan of the upper side of wax-‐up by selecting the “OK” button. When complete, carefully rotate the arm of the impression holder so that the lower side of the wax-‐up will face upwards. The user is prompted to do this as shown below: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐109 The result of the two scans will display as shown below within this example. Note all sides of the scan will be merged together at this point. Next, remove the sprue from the scan by using the editing tools within the “Remove Scan Faces” option to cut, fill hole and smooth the area of connection as shown below: When done, the contact edge with the sprue should be smooth and filled. To this point the model has been scanned, the wax-‐up has been scanned and next, the wax-‐up it to be scanned while resting upon the model. This scan will provide the ability to “key” the model with the wax-‐
up so that the margins on the model will be morphed into the wax-‐up scan. This procedure is described as follows. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐110 To fit the scan of the wax-‐model onto the stone model, a common reference has to be scanned. This is done using the “Occlusion key” scan, where the wax-‐up is scanned on the model. To do, select the “Occlusion key” icon (as shown on the left). The wax-‐up needs to be repositioned on the model using common points of reference. To do, right click on the wax-‐up and select the “Reposition waxing on arch” option from the submenu, as shown below: Select three common points between the two scan, starting with gray scan first. It is important to select the same three common points, in the same order, on the blue scan. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐111 Once the common points have been selected on both models, the repositioning occurs as shown below. Next, mount the dies onto the multi-‐die platform. Then select the “Multi-‐die” icon to precise scan the two dies. The system will indicate the positions to use within the multi-‐die plate. Next, define the margins as usual (please refer to chapter 6.1). Once the dies have been scanned and the margins are defined, the User is returned to the above screen. Next, select the blue “exit” button as shown above. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐112 When exiting from the scan application, the next step is to extract merging lines for the preparation(s). What this means is the User will need to do the following for each die: 1. Move the handles of the active contour area (circle) to capture all the anatomy (be careful not to clip any margin or anatomy surface 2. Then select the “Set extraction axis” button 3. Then select the “Next” button to move onto the next die. 4. Repeat the above for each die. When done defining the last contour area, select the “OK” button. 5. The User will then be prompted to “Route” the case, select “Yes”. Next, select the “CAD Engine” tab to generate a CAD model from the scanned data.

DWOS 3.0 user guide STI75-‐0028 4-‐117 Cleaning the surfaces (please refer to chapter 4.2.1.10) and filing holes (please refer to chapter 4.2.1.11) are useful procedures on a partial framework scan. When done, select the blue exit button and proceed to the CAD Engine step. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐118 4.2.10 How to Scan for a telescopic coping The scan to generate a telescopic coping, is the same scan procedure as to scan for a full crown. The difference is that the User will define telescopic axis and telescopic parameters as described within this section. Proceed as described within chapter 4.2.1 “Scan with standard holder” to install the model within the scanner and initiate the scan session. The orientation and definition of area of interest, model tooth number assignment, precise arch scan, precise die scan and margin line editing are to be completed as usual. Within the insertion axis definition, first define the telescopic axis (blue dot) and then the insertion axis (green dot) as shown below. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐119 The tab called “Telescopic Crown Params” will allow you to define telescopic crown parameters as shown below: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐120 4.2.11 How to Scan to Generate a Diagnostic Crown The objective is to scan a diagnostic crown (perhaps made by hand) to be used to generate an exact replica of an existing tooth, gingival area or prepared tooth. The overall scan process is very similar to scanning for a full crown with a few modifications when scan and unprepared tooth. The procedure is as follows: Open a new order as usual, however, when defining the type of prosthesis, select “Diagnostic Crown” option as shown below: Proceed as described within chapter 4.2.1 “Scan with standard holder” to install the model and launch the scan session. The orientation and definition of area of interest and model tooth number assignment are done as usual. However, when at the precise scan step, do not request a precise scan but select “Extract scan from arch scan”. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐121 Next, right click on the scan and select “Edit margin”. To simplify the margin definition, use the "No optimization (manual)” option and indicate the margin at the base of the tooth. Select the “OK” button to continue. Next, deselect the “Project Margin projection on surface” option to allow the margin to go through the proximal areas. Note, when arriving at the inter-‐proximal areas indicate the margin handles on either side of the missing area (i.e. refrain from placing handles in the missing surface area). Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐122 If scanning an unprepared tooth, request the computation of a virtual preparation within the coping parameters table as shown below: If no tooth is present, a margin must be defined on the gingiva. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐123 Also, the option “Compute Virtual Preparation” should be unchecked as shown below. A diagnostic crown can also be created over a prepared tooth. To do, scan it exactly as a crown or coping. If you decide to use the CAD mirroring function, scan the tooth to be mirrored as a diagnostic crown on the unprepared tooth. To complete the process, select the blue exit button to exit the scan function. Next, enter the “CAD Engine” to compute the model from the scan. Finally, enter the “CAD Application” and make any modifications (if necessary) and finalize the design and route to production as normal. Dental Wings inc.

It will also be possible to define Dental Points. Open a new order as usual, however, when defining the type of prosthesis, select “Inlay-‐Onlay” option. (If Inlay-‐Onlay type does not appear in the list, activate it in the available type in material definition). Proceed as described within chapter 4.2.1 “Scan with standard holder” to install the model and launch the scan session. The orientation and definition of area of interest and model tooth number assignment are done as usual. Precise scan and accurate scan of inlay-‐onlay are also done as usual. Margin line is a little bit different; the DWOS software manages two different lines: • the margin line of the tooth including the inlay-‐onlay cavity • the cut line following the cavity Specific software tools have been developed for inlay-‐onlay with automatic strategies adapted for each type of lines First, after defining three points (displayed in green) at the position of the margin line, the software submits a proposal of the margin line. The margin line can be adjusted as usual Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐125 When the margin line is validated, the software automatically moves to cut line definition. After defining three points (displayed in red) at the position of the cut line, the software submits a proposal of the cut line. The cut line can also be adjusted Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐126 In the right vertical bar, a new icon exists for inlay-‐onlay “Set valid dental points”. This icon will allow describing specific dental points (cusp, ridge, fossa) on the remaining part of the tooth supporting the inlay-‐onlay. Only define point existing on the scan and not where it should be. Left click on the position where you want to define some specific points, position can be adjusted and deleted by clicking on an existing point. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐127 4.2.13 How to Scan an Anatomical Veneer Scanning an anatomical veneer is quite similar than scanning die, changes will exist on margin line definition. It will also be possible to define Incisal Edge. Open a new order as usual, however, when defining the type of prosthesis, select “Anatomical Veneer” option. (If anatomical veneer type does not appear in the list, activate it in the available type in material definition). Proceed as described within chapter 4.2.1 “Scan with standard holder” to install the model and launch the scan session. The orientation and definition of area of interest and model tooth number assignment are done as usual. Precise scan and accurate scan of anatomical veneer are also done as usual. Margin line is a little bit different; the DWOS software manages two different lines: • the margin line of the tooth including the veneer cavity • the cut line following the cavity Specific software tools have been developed for veneer with automatic strategies adapted for each type of lines First, after defining three points (displayed in green) at the position of the margin line, the software submits a proposal of the margin line. The margin line can be adjusted as usual Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐128 When the margin line is validated, the software automatically moves to cut line definition. After defining three points (displayed in red) at the position of the cut line, the software submits a proposal of the cut line. The cut line can also be adjusted Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐129 Then, a proposal of Incisal Edge is submitted, it can be adjusted. In the right vertical bar of margin window, a new icon exists for Incisal Edge Edition. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐130 4.2.14 How to Scan a Diagnosis Pontic Diagnostic pontic is used to generate a full anatomy that will fit on a defined gingival area. It could also be used when creating an “usual” pontic for being able to define the gingival area. The overall scan process is very similar to scanning for a full crown with. Open a new order as usual, however, when defining the type of prosthesis, select “Diagnostic Pontic”. Proceed as described within chapter 4.2.1 “Scan with standard holder” to install the model and launch the scan session. The orientation and definition of area of interest and model tooth number assignment are done as usual. Diagnosis pontic area will not be displayed as Pontic and will need to be accurately scan ( at the precise scan step, do not request a precise scan but select “Extract scan from arch scan”) A margin line has to be defined for a Diagnosis Pontic, right click on the scan and select “Edit margin”. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐131 To simplify the margin definition, use the "No optimization (manual)” option.

DWOS 3.0 user guide STI75-‐0028 4-‐134 4.2.16 How to Scan Cases Mounted with Articulator The SAM articulator is delivered with the 7Series and is an optional add-‐on product with the 3Series. The procedure is to first articulate your stone models using the magnetic plates that are delivered with the articulator. These plates are attached to the both the upper and lower stone model arches and placed within the articulator. Please see the articulator instructions for proper use. Once the upper and lower arches are articulated, carefully remove and place the each arch into the scanner, leaving the magnetic plates attached to each arch. These plates are compatible with the scanner and will lock into place via the magnets much like the standard holder. Follow the usual scan procedures for the “standard holder”, followed by the CAD Engine step. When within the CAD design step, the model will then display the following icons. To access the articulator information, select the articulation icon. Within the articulation function, excursive movements can be emulated respecting changeable parameter settings. Once satisfied with the movements, exit this function by selecting the “OK” button. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 4-‐1 5 Crown and Bridge CAD Session 5.1 CAD Principles 5.1.1 CAD Engine & Proposal Editing The CAD prosthesis design function is divided in two steps: • CAD engine, which automatically converts scanned data to submit to the CAD Application for prosthesis design • CAD Application, which provides editing tools to customize the auto-‐generated proposal Both the CAD Engine and CAD Application are accessed through main toolbar. CAD Engine CAD Application When selecting the CAD Engine function, the computation of all scanned cases automatically begins and will display its progress as shown below: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐2 The status “All Prostheses Done” is displayed when the computation of an “entire” order is completed. The status “Prosthesis Done” means a particular “item” on an order has completed its computation. note this computation must be completed on each order before continuing onto the CAD Application as shown below: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐3 When selecting CAD Application, the application main window is displayed and lists the orders ready for CAD review or editing. To select an order, drag it and drop it into the main window or double click on the order number and the design proposal will display within the “CAD Design View” window. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐4 5.1.2 Differences between Anatomy & Overlay The Dental Wings prosthesis design software has adopted an “Outside to Inside” design strategy. This approach enables you to design full contour crowns by taking into account the full clinical situation in one design step. Once done with the crown design, the framework design is automatically computed from the full prosthesis morphology, if requested. To achieve this, the DWOS CAD software works with two different elements: • Anatomy: full contour morphology design • Overlay: framework design Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐5 The DWOS CAD software includes advanced display features that assist the User when working upon these two elements: • Transparency view • Cross sectional view where a slice of each element is visible: anatomy and overlay Anatomy and Overlay designs have context sensitive adjustment options. For example, the occlusion is adjusted with the anatomy and a dental band is adjusted with the overlay. These tools are described in detail within this chapter. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐6 The overlay is computed with respect to the Anatomy design. Therefore, when a modification is applied to the Anatomy, the Overlay is automatically updated. For example, in the case of a clinical coping, the DWOS software will update an overlay to compensate for the porcelain thickness. Below illustrates this example: Initial Situation Anatomy Edited Automatic Update of Overlay Constant Thickness for Porcelain However, a modification applied to the Overlay will not affect the Anatomy. If edits are first applied to the overlay (substructure) prior to anatomy edits, the DWOS CAD software will take into account these overlay edits and the anatomy can be “readapted”. The overlay’s defined ceramic interface will always respect the “minimum thickness” followed by the “cement gap” that are defined within the material default settings or overwritten by the User. In the case of an anatomical coping, the overlay will be projected on the minimum surface from the equator down, to give space for the ceramic, even if an equator space of 0 mm is set. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐7 5.1.3 Clinical Parameters Definitions The Dental Wings prosthesis design software is clinically oriented and allows the User the ability to set the clinical parameters needed for design. The parameters are managed in two different ways: • Parameters tables for general prosthesis parameters, e.g. prosthesis type and minimum thickness. Parameters tables will differ according to prosthesis type. These parameters will be used for the computation of the automatic proposal of the prosthesis. • Tool parameters to manage local parameters, e.g. diastema value or prehension item diameter. Please refer to chapter 4.2.1.8 for an overview of Parameter tables. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐8 Examples of some tools parameters: Diastema definition Dental band parameters Prehension item parameters Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐9 The tools window parameters can be moved by clicking within the banner and dragging it to a new location: The cross sectional view can also be moved. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐10 Some tools window parameters can also be reduced or expanded by clicking on the expansion arrow within the blue header: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐11 5.1.4 Recompute and Re-‐Adapt One of the main advantages of the DWOS Crown & Bridge CAD software is its unique flexibility that allows the User the ability to change the elements of a prosthesis such as: • Margin and Collars lines • Friction Parameters • Anatomy • Prosthesis Type • Material choice • Bridge organization While still being able to generate a automatic computation. These changes can be applied at anytime. Only one element cannot be changed: lower or upper arch definition. Therefore, be careful when the arch (upper or lower) This selection cannot be changed once defined. Refer to chapter 5.1.7 Edit order to know to apply change to all the order. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐12 To change an element of the prosthesis, right click on the prosthesis and select the appropriate item within the menu. If selecting the “Edit margin line” option, the edit margin line window is activated (please refer to chapter 4.2.1.8). Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐13 If selecting the “Recompute” option, the User may change the insertion axis and friction parameters. This menu will re-‐compute everything; anatomy, overlay and connectors, if any, as if the design was coming straight from the CAD Engine function. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐14 When selecting “Recompute” option, the Prosthesis Parameters window will display as shown below and the listed parameters may be modified e.g. insertion axis, cement values, minimum thickness, etc. (please refer to chapter 4.2.1.8 for more details). Prosthesis type and prosthesis parameters (both Coping and Reduction), can also be modified through the two others tabs. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐15 The “Re-‐Adapt Anatomy” option, allows the User to change the tooth number and referenced anatomy kit (please refer to the next section for further details). Re-‐Adapt Anatomy readapts the corresponding anatomy to the current clinical preparation; this will also recompute the overlay and connectors (if any are present). Select the new tooth number and/or family kit and press the OK button.
Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐16 The “Recompute Overlay” option, allows the User to change the prosthesis type and the associated parameters. It should be noted that even if the re-‐computation of the overlay is automatic within the software, you can force an overlay computation to more accurately respect the Equator handle, Cervical handle, Groove handle, Cusp handle and Reduction Parameters. They can also be changed using the same interface as in the parameters validation in the margin design view. The overlay that defines the ceramic interface, will always first respect the minimum thickness value and after try to respect the cement gap given by the user. Thus, the final computation will always be reconciliation between the two parameters. In the case of an anatomical coping, the overlay will be projected on the minimum thickness from the equator down, to give space for the ceramic, even if an equator space of 0 mm is set. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐17 Since the functions are “context sensitive”, depending upon the prosthesis type, the number of parameter tabs will vary. These parameters will be detailed within section 5.4.2. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐18 Recompute bridge will recompute all the order as it was routed back to CAD engine and reprocessed by CAD engine. It could be very useful for a bridge with common insertion axis where you change the insertion axis: recompute bridge will ensure that all items of the bridge are recomputed and you’ll need to manually recompute all of them one by one.
Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐19 5.1.5 Anatomy kit When computing the automatic proposal for the prosthesis, DWOS cad software uses an anatomy kit library that contains morphology and particular clinical information for each tooth. DWOS prosthesis design software provides two different families: • DW kit: usual resolution family (default family) • DW Hi Res kit: high resolution family (recommended for full or Overpressed) You can create additional kits (refer to chapter 8 Anatomy kit editor). The choice of the anatomy kit is made when creating the order. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐20 The kit choice can be changed when re-‐adapting an anatomy According to the choice of kit, the automatic proposal will change. For example, on this case of a single 37: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐21 Using DW kit, the automatic proposal will be And using DW Hi Res kit Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐22 The influence of the anatomy kit can be observed when looking the morphology of the 37 in the two kits: DW kit DW Hi Res kit Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐23 5.1.6 Reminder When accessing to a local menu of prosthesis by right click, its tooth number is displayed in the banner of the menu. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐24 Remind also that DWOS software includes many useful functions described in chapter 2.3.3 Display Management. Do not forget to benefit from Cross section views, Clips Planes with grid and measure tool, The Visibility and Transparency buttons. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐25 5.1.7 Edit order Edit order is the ultimate tool bringing full flexibility to the order within the CAD design, all the elements of the order definition can be changed within CAD session and the DWOS Crown & Bridge software will recompute everything automatically according to user change. Only arch selection (lower or upper) cannot be changed with Edit order. When selected, Edit Order option gives access to the order definition window: With the classical order definition menu, you can change the order definition. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐26 As an example, see how to modify a 3 units bridge 14-‐15-‐16. Edit order for removing 14 from the bridge by right click on the 14 And redefine 14 as single unit Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐27 The order is automatically recomputed as a single unit on the 14 and a bridge 15-‐16 with cantilever pontic 15 To come back to original situation, Edit order and create a 14-‐15-‐16 bridge The order is automatically recomputed as a 3 unit bridge Dental Wings inc.

DWOS 3.0 user guide STI75-‐0028 5-‐76 5.10 Bridge DWOS CAD software can manage bridge up to 16 elements. Bridge management is very similar to single units managements. DWOS offers you to manage common or individual insertion axis for the dies of your case. DWOS software can deal with two types of pontic: • Pontic (for ceramic) • Full pontic DWOS software submits automatic proposal for connectors that you can edit if needed. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐77 5.10.1 Insertion axis of a bridge According to the types of material and manufacturing equipment (i.e. a 4 axis milling machine), you will have to decide if you manage a same insertion axis for all the elements of a bridge or individual axis for each die. This choice will be done when during Margin edition (refer to chapter 4.2.1.8) and can be modified using recompute function (refer to chapter 5.1.4). If you decide to manage same insertion axis for all the elements, select the Enforce 3-‐Axis Milling checkbox. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐78 You have two ways to define insertion axis: use Auto insertion axis function that will automatically the axis that minimizes undercuts. or adjust the axis manually and then press Set insertion axis. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐79 If you decide to manage individual axis, you have to define for each die its own axis. Uncheck Enforce 3-‐
Axis milling and be sure that the Same insertion axis for all elements is not selected (see below). Repeat the axis definition for all the dies of your bridge (axis will be displayed for the current die) Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐80 In case of axis change, DWOS software will warn you. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐81 Same insertion axis for all elements allows to manage a common axis for all the dies of the model. It is useful for example for case with attachment or case with several customized abutments that will support a bridge. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐82 5.10.2 Pontic Pontic management is similar to prosthesis management, the overlay will be computed from the full anatomy of the pontic. First, as usual you define your pontic type and the associated parameters. The accessible type of pontic will depend on your material definition. (see chapter 9.4). DWOS software manage pontic (for porcelain) and full pontic. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐83 CAD engine computes a proposal for pontic anatomy and overlay. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐84 Usual local menus are accessible on a pontic Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐85 Pontic can also be edited using classical customization tools: Specific Recompute Pontic Shape button will recompute the pontic for proposal a morphological shape taking into account your handle editions. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐86 5.10.3 Connector Proposal for Connector is computed automatically using its adjacent teeth information. Connectors are displayed using colors that indicate the connector diameter with regard to the specification defined for the minimum connector size in the material management software (see chapter 9.4): • Red means under the minimum value • Grey means over the maximum value • From Yellow to Brown indicate evolution from maximum to minimum value. The software gives you information and warning regarding connector size but doesnot apply limitation in the connector design. YOU ARE RESPONSIBLE OF THE CONNECTOR DESIGN ACCORDING TO MATERIAL, POSITION OF THE BRIDGE (FRONT, POSTERIOR) AND ITS SPAN Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐87 A local menu is accessible on a connector Connector can be edited using specific editing tool: Editing tool includes a parameter window (that can be moved) and a cross-‐section is displayed at the bottom right of the window. The cross-‐section plane position is enclosed in the black circle; it can be moved using the arrow keys on the keyboard Cross-‐section view also provides information on the maximum, minimum and current section of the link. It is displayed using mm2 unit. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐88 Edit connector tool displays handles on the connectors. The two areas on mesial and distal tooth are available for edition (blue lines and handles), including the center section (orange handles). To adjust the area shape just press and drag the handle where you need it to be. You can reduce or increase the diameter of the area by rolling the mouse-‐wheel while pressing on a handle. For example, if you want to make the connector thicker at the center, press the mouse button on an orange handle and simultaneously roll the wheel. It is recommended to hide the anatomies while editing a connector; use the Show/Hide Anatomy Button at the top center of the main 3D window. To center the view on the current connector just double-‐click on it, it should zoom and center the camera. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐89 Using Show Mesial Contour or Show Distal Contour in the parameter window will allow you to design easily the connector on the pontic or the adjacent element. Note the parameter window includes on 3D view that allows you to check the results of your handle adjustments Correct interference with gingiva will automatically reshape the connector to generate room between the connector and the gingival. The value of this space is adjustable. Recompute connector will automatically recompute the connector without modifying the mesial and distal contour. It can be useful to cancel edition applied on the orange handle. Before recomputing, the connector shape can be changed (see chapter 9.4.10 Connections parameters) Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐90 A connector contour designed on one side (e.g. Mesial) can be projected on the other side of the connector using Mesial -‐> Distal or Distal-‐> Mesial button. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐91 When you are satisfied with the connector edition, validate by right-‐clicking in on the background or use the validation buttons (OK/CANCEL) in the parameter window. or use the validation buttons (OK/CANCEL) at the top right corner of the 3D view. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐92 5.11 Wax-‐Up adaptation DWOS software allows adapting the anatomy to a wax-‐up scanned. When you load an order with wax-‐up scanned, the software will display in addition to the anatomy and the overlay the wax-‐up scanned. CAD engine has not used the wax-‐up to compute the proposal for the anatomy. Wax-‐up adaptation will modify the anatomy to respect morphological information coming from the wax-‐up. Note the differences between the wax-‐up scanned and the proposed anatomy Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐93 If needed, wax-‐up can be modified or its position can be adjusted with a specific tool similar to the one used for adjusting antagonist position (refer to chapter 4.2.2). Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐94 When the wax-‐up position is OK, you can request for adaption on wax-‐up through local menu of the anatomy. Automatically the view is switch to an occlusal view and the wax-‐up adaptation window is displayed. Do not rotate the view. Stay in occlusal view during wax-‐up adaptation Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐95 The first step of wax-‐up adaptation is defining relevant area on the wax-‐up by adjusting the blue line around the wax-‐up element. Adjust it by moving the handles, you cannot add new handles. When the line is OK, you have to define clinical points. In the case of this central, click left on the position of the mesial fossa, then central fossa and distal fossa. Positions can be modified before computing the adaptation. The list of clinical points to define will change according to tooth number and is indicated Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐96 When the clinical points are properly defined, select Adapt Anatomy on WaxUp button in the following window. Project button applied a projection of the surface of the anatomy to the wax-‐up without respecting the correspondence between the clinical points defines on the waxup and those of the anatomy. Reset WaxUp info cancels the modification of the blue line around the wax-‐up and fossa definition. Smooth applies a global smoothing on the anatomy. We recommend you to use it after adaptation. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐97 When you are satisfied with the waxup adaptation, validate by right-‐clicking in on the background or use the validation buttons (OK/CANCEL) in the parameter window. or use the validation buttons (OK/CANCEL) at the top right corner of the 3D view. The adapted anatomy is displayed. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐98 5.12 Prosthesis with cutback margin If your prosthesis has porcelain butt margin, you have defined the butt margin line during margin edition step (refer to chapter 4.2.1.8). This butt margin line can be modified during CAD using Edit margin line in local menu. If the prosthesis has an anatomy over, the cervical part of the anatomy will be adapted to the real margin not the cutback. The cervical part of the overlay will be adapted to the cuttback margin. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐99 If an overpressed corwn is computed it will respect the the real margin as well. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐100 5.13 Simple Coping with Wax-‐up When loading a simple coping with wax-‐up order, DWOS CAD software will display the wax-‐up on the model. No automatic proposals for anatomies, nor overlay are computed. Wax-‐up margins must be edited for each die. To do, select the “Edit waxing margin” option. The wax-‐up margin editing windows appears as shown below: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐101 Using the edit margin icon, request an automatic margin proposal for the wax-‐up to be generated. Next, manually adjust the wax-‐up’s margin line. It is recommended the external side of the wax-‐up be utilized when editing the margin. Repeat the same editing procedure for all the dies within the case until done. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐102 Next, you can customize the prosthesis using the usual “Add/Remove material” function as shown below: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐103 5.14 How to Create a Diagnostic Crown The following procedure will create a diagnostic wax-‐up on an unprepared model. It acts like a Full Crown but has a virtual preparation. When loading the order, the diagnostic crown is computed over the model. If the diagnostic crown is positioned upon an existing tooth, it can be used as a wax-‐up to duplicate when scanned. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐104 After the scan, the wax-‐up morphology is replicated. A virtual preparation will be computed using an automatic cutback from the full anatomy using the predefined coping parameters. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐105 If no tooth is present, then the option “Compute Virtual Preparation” should be unchecked, and the internal surface will be projected onto the existing gingiva. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐106 A diagnostic crown can also be computed over a prepared tooth and no Virtual Preparation computation will be needed. In this case, you can benefit from the “Mirror Anatomy” function. This function will also use an anatomy, scanned as a diagnostic crown and properly adjusted, as an anatomy kit, i.e. the software will not reproduce exactly the mirror anatomy but use it during the morphology adaptation. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 5-‐107 5.15 How to Generate a Telescopic Coping The DWOS CAD software can automatically generate the automatic proposal of a telescoping coping.

However, there are a few things the User needs to do first. The Dental Wings DWOS software implant module supports most commercially available implant systems. To begin, you need to choose the implant system brand(s), for which you wish to design custom abutments. Next, an “Implant Kit” for each brand of Implant system will need to be defined (step by step instructions are listed are described within this chapter). Please note that most implant interfaces are proprietary to each vendor and typically available for purchase from either your implant system supplier or through third party manufacturers. Once you have decided which implant system to work with, follow the instructions within this chapter on how to define “an Implant Kit”. The procedure to generate a kit is performed with the Dental Wings “Implant Kit Editor” and performed only once per kit. Step by step instructions are provided under “How to define an Implant Kit”. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐1 11.2 Implant module The DWOS software implant module provides the tools to design single or multiple custom abutment designs within the same arch. To fully implement the Implant module, the following is required: • A scanning jig, which is the physical piece that is screwed or placed inside the implant stone model and when scanned, it will define the position of the implant within the patient. • A defined implant kit that describes the geometric and dimensional information of the kit’s components: scanning jig, implant body, implant interface (if used), implant transfer (if used) and screw (if used ). The following is an overview of the steps to design custom abutments: 1. Verify for each material type that will be used in your Custom Abutment designs, to activate the “check” mark associated to the “Biomediface (Abutments)” option within the “Output Formats” pull down 2. Create a new order 3. Scan model using a scanning jig 4. Initiate the CAD Engine to generate a CAD model 5. Using the CAD application, design your custom abutment 6. Generate the production output When the implant module is installed, the icon of CAD application includes a screw as shown below: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐2 11.3 How to Define an Implant kit The different implant specific components: jig, implant, implant interface, implant transfer and screw, are used to design a customized abutment. These components are defined within the Dental Wings Prosthesis Design software using the Implant Kit Manager. To start the Implant Kit manager, press the gear icon within the main tool bar and select Implant Kit. The main Implant kit window appears: This window is organized in two areas: • List of existing implant kits • Description of selected implant kit To import an existing implant kit library, right click on Implant option displayed within the upper left part of the window and select Import Implant Kit from the assistant. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐3 Identify the path location of your implant kit library and press Open.

DWOS 3.0 user guide STI75-‐0028 11-‐33 Starting from this bridge definition, the software submits an automatic proposal as usual: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐34 11.5 DHS – Dental Hub System The DHS software is the communication backbone of the DWOS solution and is fully integrated. This integration is key to its ability to seamlessly transfer data from any step in the DWOS process to another, within an easy to use and secure environment. To move data, the User “subcontracts” the data to the desired place. Most commonly, any case (regardless of its step) can be subcontracted to a Design or Production Center. Moreover, once transferred, information about the case is “real time” and available to the sender. For example, once subcontracted, the User can see from his station if the case is being milled, packaged and/or shipped. This intelligent two way communication greatly assists in the User in case management. DHS is also capable of subcontracting work at different operational steps (e.g. subcontracting open prosthesis designs or completed designs for manufacture). Intelligence is built into DHS. For example, finished designs can be subcontracted only to a Production Center that is defined as “capable” of producing a given material type. Scans can be subcontracted (outsourced) to a Design Center for completion and later subcontracted to a Production Center. Finally, by design, DHS has the flexibility to be easily be updated to grow and evolve with your environment. The communication can be both internal or external (a partner) who is defined within the communication framework and using DHS. The DWOS software indicates if a valid DHS connection is present. An indicator is located with the lower right main DWOS window. Red indicates no DHS connection. Green indicates a DHS connection.
Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐35 11.5.1 DHS configuration To define and configure a DHS connection, utilize the DHS preferences settings found in lower right corner of the main DWOS window. icon Enter the information within the DHS panel below. Please note that each site’s data is unique. Therefore, it is suggested you refer to the information provided by your Dental Wings representative prior to filling in the panel. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐36 11.5.2 How to Subcontract using DHS The DHS software can easily subcontract a design to Manufacturing. Subcontracting an order is done within either the Administrative Application or Production Management functions. When within either function, the subcontract menu is accessed by a right click on either the order number or item number and subcontract a design or order as shown below. An order item or entire order can be subcontracted as shown below. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐37 To Subcontract a completed design or an order that is within the “CAD engine” state (and beyond), you will “Subcontract Design”, accessible at the order and order item level within the Administrative Application via a right click on either the order or order item as shown below. Orders at the “CAD” step. Orders at the “Production” step. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐38 When selecting a Job to Subcontract: A window is displayed that summarizes routed orders or order items. Order information can be passed to the Production Center when typed within the field above. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐39 This window allows the User to select the desired destination Production Center to which to route. And the ability to define a choice of material color, if defined, for a given Production Center. Press OK to subcontract the job. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐40 DHS will now automatically transfer the job files to the requested Production Center. The status bar, show the transfer progress. DHS updates the order status and identifies that the routed jobs have been successfully received by the Production Center and are awaiting their acceptance (i.e. waiting within their “inbox”). Once accepted, the status is updated to reflect the job acceptance by the Production Center as shown below. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐41 Production management automatically provides a unique internal order ID (listed within the Remote ID column) to ensure all cases can be easily tracked, especially if routed more that once or to more than one Production Center. In addition, the “Remote Status” column provides the routing party with a real time disposition of their order. When subcontracting an open design, the process is the identical, however, the DHS update status will reflect the appropriate status. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐42 11.6 Nesting Station-‐ Milling Job Block Preparation & CAM Generation The Nesting Station function provides an easy to use method to manage milling block preparation that are loaded with completed designs. In addition, an integrated CAM (Computer Assisted Manufacturing) process can be used for milling through the use of a CAM engine. To begin the Nesting Station function, click on its icon within the main toolbar as shown below: The main Nesting Station window will appear: This window is organized in 3 areas as follows: • Orders ready to be produced (you can filter for new orders only) • Active milling block • Orders placed on active milling block A nesting specific toolbar is also present on the right side. There are three general steps when using this feature which are: 1) generation of block(s) definition(s), 2) nesting of order items of completed design within the block and 3) generation and transfer of a CAM job to be milled. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐43 The first step within the procedure is to create and define a milling block to be later used with the orders or order items when nesting. To do, select the block option icon: The Nesting Station function will define disks and cuboid blocks. It is important to please refer to your block material supplier to obtain the needed information within the fields below: Once the block information is entered, save the block by pressing the “Save Block” button. You are now ready to nest order or order items into this newly defined block. The next step is to load the block with designs to be milled. To do, select the block from the “Nesting Blocks List” by clicking on the block’s name. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐44 When a block is loaded, an empty block is displayed showing its top and side views. As defined by the loaded block definition, the Nesting Station function displays in green the orders that fit within the block and in red, the orders that do not as shown below: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐45 To add an order or an item order on the block, select and drag and drop onto the block at the intended position. The green “ +” button as shown below, will also add the order to the block placing the item within the center of the block. Repeat procedure for the order or order item intended for the block. Editing Options: An item may be removed from the block by selecting item to make active, then pressing the “DEL” key on the keyboard to remove active item from the block. The “ “ button will also remove selected item from the plate. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐46 An item can be moved within the disk by dragging to a new block position as shown below: An item can be rotated by selecting an item, then while press and holding the left mouse button, rolling the mouse wheel. The Nesting Station function automatically checks during order positioning for interferences with other items and violations of defined minimum distance to edge requirements. Placed items with boundary violations are displayed in red to alert the User. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐47 It is recommended that block usage be optimized by arranging orders as shown below. Note, unused areas of blocks may be used during another milling run, as a visual record of block usage is kept. Once all desired items are loaded into the block, connectors must be generated. These connectors can be added either manually or generated automatically. To do, right click on an item and select the “Edit Connectors” option to define milling and sintering connectors. The “Nesting Connector Designer” window appears as shown below: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐48 The toolbar below provides the connector options which are shown below: Add a Milling Connector (manually) Add a Sintering Connector (manually) Automatically Add All Connectors (both milling and sintering) Automatically Add Milling Connectors Automatically Add Sintering Connectors Remove Selected Connector Remove All Connectors Some milled materials require post-‐milling sintering, e.g. zirconia, that will slightly shrink the prosthesis to a known controlled size. Materials of this type require “sintering connectors” (or supports), that the Dental Wings software can automatically or manually generate. These sintering supports are commonly used with bridges units. Similarly, milling connectors are required to support the milled prosthesis within the block itself. The milling connectors can also be automatically or manually generated by the User. There is also an option that will generate both sintering and milling connectors using the “Automatically Add All Connectors” option. To manually add a milling connector, left click on the “Add Milling Connector” icon. When the mouse is moved onto the surface of the prosthesis, a connector will appear and will move with the mouse displaying either green or red, until placed by left clicking. The software validates the connector placement. That is, when the connector is “green” the placement is valid, when the connector displays “red” the placement is invalid (e.g. too close to another connector). Both of these examples are shown below: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐49 To manually add sintering connectors, it works in a similar way using the “Add Sintering Connector” icon: These connectors can automatically be generated when loading the block when indicated within the block definition by “checking” one or both of the options shown below. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐50 References numbers can be displayed for all the items by selecting the central visibility icon. The reference number for only one order can also be displayed. To do, select the “Toggle Reference Number” option as shown below: Undercuts can be checked by selecting the central view icon, then the “Toggle Undercuts” within the local menu as shown: Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐51 An external order can be added to the block. To do, select the “Import external STL file” icon. As shown below, enter the path location of the STL file to import. Repeat the above connector options until all need connectors are generate. Next and final step is to generate a job to be milled. To do this, left click the “Mill Block” icon: The Nesting Station allows for a direct interface between Dental Wings and a CAM engine. This “handshake” between CAD and CAM occurs when you the pass the part nesting just completed, to the CAM engine. This occurs when filling in the following fields below. When completely filled out, begin the job creation for the mill by selecting the OK button. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐52 The CAM engine will begin calculating the cutting tool paths and generate the milling job. When done, the confirmation notification is displayed as shown below: The “Block Options” feature manages the use blocks. Using the “Nesting Job Options” tab, the User can visually traverse through the past physical usage of each block and to allow continued milling on the unused portions of the block. To reuse a block, select the desired block and press the “Load Job” button. Dental Wings inc. DWOS 3.0 user guide STI75-‐0028 11-‐53 Once loaded, past milled designs will display in the used area of the block to prevent the User from placing a design on the block in an area where no material exists.
