Application status and prospect of PEEK oral biomaterials
The advantages and shortcomings of traditional dental biomaterials such as metals and ceramics,and the remark-able advantages of polyetheretherketone(PEEK)which possess excellent physical and chemical properties,good biocompatibility and aesthetics in the field of stomatology were introduced.The application status,disadvantages and challenges of PEEK in ortho-dontics(orthodontic archwires,early appliances,and fixed lingual retainer),prosthodontics(crown restoration,post-core,fixed partial denture,removable partial denture,and maxillofacial prosthesis),oral implantology(dental implant,healing abutment,and bone scaffold),oral and maxillofacial surgery(jaw reconstruction,temporomandibular joint reconstruction),and periodontics(peri-odontal splint and occlusal splint)were reviewed.Various methods of PEEK modification to improve its performance and applicabil-ity in clinical applications were discussed.Finally,the future application prospect and development direction of PEEK in the field of stomatology were also prospected.
