Implant prosthetics requires the coordination of
different types of materials.
The SR Phonares II is composed of NHC and PMMA
material.
The graph below shows the wide range of materials
involved in implant-supported removable restorations.
It is essential that the materials are compatible with
each other to ensure that the restoration offers
optimum stability and longevity.

FACTS
• In the natural dentition,
the Sharpey's fibres are responsible for
anchoring the teeth to the alveolar
bone. The gap created by the perio-
dontal ligament is approx. 0.15 to 0.2
mm in width. Natural teeth are 10 to
100 times more flexible than osseo-
integrated implants.

• The threshold of tactile perception is
10 times higher for implants than for
natural teeth.
