Polycarbonate
Polycarbonate is one of the thermoplastic resins named in non-metal clasp partial dentures, where low elastic modulus can reduce support.
[2]The short answer
Polycarbonate is a thermoplastic resin named for non-metal clasp removable partial dentures with support limitations.
[2]
What is polycarbonate in a denture?
Which property is the concern?
The concern is low elastic modulus. In the non-metal clasp design described, this can mean inadequate support on the abutment teeth.
[2]Where are denture-base polymers used?
What other framework materials are in the discussion?
The comparison includes polymer frameworks and metal frameworks. PEEK and PEKK are high-performance PAEK materials considered for fixed and removable prosthetic frameworks.
[2]Why can a non-metal clasp design need extra attention?
A thermoplastic removable partial denture may still lack support on its abutment teeth, even when a metal framework is incorporated. That limitation is tied to the elastic modulus of the named thermoplastic resins.
[2]What are the wider polymer-framework limits?
Polymer frameworks are reported to degrade faster than metal and have high thermal expansion. Chemical leaching is also identified as a possible cytotoxicity concern.
[2]Frequently asked questions
Does a non-metal clasp denture always provide the same support as metal?
The reported limitation is inadequate support on abutment teeth with thermoplastic resins that have low elastic modulus.
