- Abstract: BACKGROUND:Polyetheretherketone is a special plastic polymer with good mechanical properties,biocompatibility,and chemical stability,which can be added with different fillers to form new composite materials and has potential clinical application value in post core repair. OBJECTIVE:To review the properties of polyetheretherketone and its composite materials,as well as the clinical application progress in post core repair. METHODS:CNKI database was searched using the Chinese search terms"polyetheretherketone,post core repair,metal post,fiber post,zirconia post".PubMed database was searched using English search terms"PEEK,polyetheretherketone post,post core repair,dental dowels".Search time ranged from January 2019 to October 2023.By reading literature titles,abstracts,and selecting the entire text,the inclusion and exclusion criteria were used to screen and finally include 71 articles for review. RESULTS AND CONCLUSION:Polyetheretherketone is a high-performance thermoplastic polymer.Experimental studies have proven that polyetheretherketone and its composites have advantages in mechanical properties,biocompatibility,aging resistance,chemical stability,adhesive properties,etc.,and have promising application prospects in the field of post core repair.The clinical application of polyetheretherketone and its composite materials as post core restorations is limited to anterior teeth and premolars,but they have achieved satisfactory restoration results.Polyetheretherketone and its composite materials are new materials in post core repair,and there are still many problems to be solved,such as whether the 3D printing equipment and printing process will affect the mechanical properties of the materials;short observation time for clinical repair effects,lack of long-term research validation.There is a lack of case reports on the use of polyetheretherketone and its composite materials as post and core materials for repairing molars,and further research is needed to continuously improve related studies.
