[Advances in the study of polyetheretherketone and its composites in the field of dental implantology].

Polyetheretherketone (PEEK) and its composite materials have garnered widespread attention in the field of dental implantology due to their good biocompatibility, mechanical properties, and corrosion resistance. The low elastic modulus of PEEK, comparable to that of human jawbone, helps to reduce the stress shielding effect around the implant, thereby enhancing the rate of bone integration. This article reviews the latest research progress of PEEK and its composite materials in the field of dental implantation, including the synthesis of materials, surface modification techniques, and applications in implant-abutment-crown complexes and full-arch denture bridges.
