Abstract:

Polyetheretherketone (PEEK) is a linear aromatic polymer with excellent mechanical properties and chemical stability. PEEK has been widely used in aerospace, automobile and precision instrument manufacturing, and other high-tech fields. In addition, the reliable bio-safety, suitable elastic modulus, and good surface properties of PEEK materials have made it widely used in the medical field. Currently, the application of PEEK and its attraction among scholars are gradually increasing in stomatology applications, such as implants, temporary abutment, and fixed and removable denture materials. In this article, the research progress of PEEK on oral implantology and prosthodontics is reviewed.

Key words: polyetheretherketone, implant, osseointegration, fixed partial denture, removable partial denture
