Purpose: This study aimed to comprehensively summarize the current state, shortcomings, and challenges regarding the use of polyetheretherketone (PEEK) in various fields of stomatology.
Study selection: This study reviewed articles retrieved from PubMed, Google Scholar, Web of Science, and ScienceDirect databases. The main keywords used during the search included “polyetheretherketone (PEEK),” “dental materials,” “orthodontics,” “prosthodontics,” “oral implantology,” “oral and maxillofacial surgery,” “periodontics” “osseointegration,” and “surface modification.”
Results: Numerous studies have highlighted the properties of PEEK that contribute to its usefulness in dentistry, including its high biocompatibility, fracture resistance, aesthetics, radiolucency, and bone-like mechanical properties. Promising applications of PEEK in dentistry include orthodontic archwires, interceptive orthodontic appliances, fixed lingual retainers, crowns, post and cores, fixed partial dentures, removable partial dentures, maxillofacial prostheses, dental implants, implant abutments, alveolar bone scaffolds, jaw reconstruction, temporomandibular joint reconstruction, periodontal splints, and occlusal splints. In addition, many in vitro and in vivo experiments have demonstrated that the in vivo bone integration capability can be effectively improved using advanced surface modification technologies.
Conclusions: PEEK has been explored in several dentistry fields owing to its excellent properties. PEEK and its modifications are most frequently used in clinical dentistry. However, most of its applications are based on in vitro or short-term in vivo evaluations. Additional long-term clinical data are required to demonstrate the applicability and superiority of PEEK in dentistry.
