Comparison Between Injection Molded Polyetheretherketone (PEEK) Framework and Cobalt Chromium Framework Removable Partial Dentures Regarding Periodontal Health of Abutment Teeth

It's a biocompatible metal alloy used in thin sections and are less bulky, provide high strength and stiffness ,conduct heat and cold for a more natural experience, enable designs that minimize the covering of the gingival margins, allow for a stable denture base, and is resistant to corrosion. Disadvantages include hypersensitivity, esthetic issues with metal display, oral galvanism, adverse tissue reactions, osteolysis of abutment teeth, and biofilm production .

It's a promising polymer-based framework material has recently been introduced which is made of polyetheretherketone polymer frame combined with acrylic resin denture teeth and a conventional acrylic resin denture base.
