Contemporary removable prosthetics require intelligent materials. They should
resist abrasion, without provoking potentially damaging hyperbalances and their
consequences. On the other hand, they must be fracture-proof to guarantee a long
wearing life in tertiary structures.
HMP-N
H IGHLY M ODIFIED P OLYMER- N ETWORK
®
HMP-N is a dental material developed for implant-borne and periodentally
supported prosthetics with biomimetic properties simulating nature.
®
Thanks to its homogeneous structure with finest crystalline filling material, the Highly
Modified Polymer Network (HMP-N ) provides a balanced combination of
properties.
®
■
Resistance to wear to guarantee vertical support
■
Shock-absorbing for impact and shear forces acting on the tooth
■
Self-regulating biomimetic adaptation reduces hyperbalance contacts
by individual "functional engraving"
■
Homogeneous PMMA layering, therefore easy processing when producing
prosthetics
■
Resistance to plaque due to the uniform PMMA structure
INTELLIGENT POLYMER
WITH INNOVATIVELY HIGH DENSITY
HMP-N
Highly Modified Polymer-Network
®
The low proportion of the crystalline filling material of silica-apatite, which is very
similar to human dental enamel and forms only around 4% of the structure, is
bonded chemically by methacryl silane bridges with the surrounding PMMA resin
matrix.
Density and structure compensate for masticatory wear stresses just as much as
shear loadings, which can lead to chipping.
Nano Filled Composite – Composite Dental Material
The innovative pairing of very fine, uniformly distributed crystalline filling material
and matching sperical polymer macromolecules of different complexity reveal an
innovative high density in polymers.
The high inorganic macro- and microfiller content can be recognized clearly in
conventional composite dental materials. If cleavage occurs in the filling material,
microcracks that can cause fractures under the action of force due to a "ladder
effect" arise. The best material is not always the hardest.

The silica apatites very similar to human dental enamel endow the HMP-N
very high resistance to wear compared with natural dental enamel. The
resistance to abrasion of this Hybrid PMMA is almost identical to composite dental materials and allows biomimetic adaption to the individual
"functional engraving" of lower tooth-guided movements.

thus chipping are reduced.

The finer-grained the filling material, the higher the load bearing
capacity of the dental material. HMP-N is an innovative hybrid PMMA
that fulfils this requirement.

ADAPTATION TO
THE OCCLUSION PATTERN
HMP-N is not brittle, it facilitates adaptation to the tooth-guided movement paths analogously to the individual neuromuscular control.
The material thus supports avoiding hyperbalances that can provoke resulting parafunctions.
