Polyetheretherketone (PEEK) has emerged as a promising biomaterial in implant dentistry due to its favorable mechanical properties, biocompatibility, chemical stability, and esthetic appearance. Originally introduced in orthopedic applications, PEEK has gained increasing attention as an alternative to conventional metallic materials in implant-related treatments. Its elastic modulus is closer to that of cortical bone than titanium, potentially improving stress distribution around implant-supported restorations. In addition, its radiolucency, reduced plaque accumulation and compatibility with CAD/CAM technologies have expanded its clinical applications. Recent studies have reported encouraging outcomes regarding soft tissue response, bacterial adhesion, and the use of PEEK in healing abutments, provisional restorations and implant-supported prostheses. However, the bioinert nature of untreated PEEK remains a challenge, necessitating the development of surface modification strategies to enhance tissue integration. The purpose of this mini review is to highlight recent evidence regarding material characteristics, biological properties, microbial interactions, and clinical applications of PEEK in implant dentistry, while discussing current limitations and future research directions.
