Abstract: Polyetheretherketone (PEEK) and its composites have excellent chemical stability, good biological properties and its mechanical properties are very close to natural teeth and dense bone, which make it become the focus of the area of oral medicine. Excellent comprehensive properties of the PEEK make it an alternative to traditional materials used in the fixed restoration, removable restoration and implant of new biological materials. This paper reviewed the characteristics of PEEK as dental materials, and the application and research of PEEK in prosthodontics.researches of PEEK in prosthodontics.
