Ivoclar Vivadent uses a variety of composite materials to manufacture composite denture
teeth
1.UDMA teeth containing inorganic fillers: Isosit
the Isosit material is not based on
PMMA polymers; instead it is composed of a
urethane dimethacrylate-based crosslinking
agent, which is reinforced with inorganic
microfillers. The inorganic pyrogenic silica fillers
considerably increase the hardness and rigidity
of the material compared with PMMA-based
materials.
This material is used for SR Orthosit teeth.

2. NHC teeth containing inorganic fillers
The SR Phonares NHC and SR Phonares II
teeth consist of NHC material, which is a
composite consisting of a urethane
dimethacrylate matrix with inorganic fillers,
isofillers (prepolymer) and PMMA clusters
embedded in the structure Schematic of NHC microstructure
