摘要：


文题释义：

聚醚醚酮：是半晶型芳香族高性能特级工程塑料聚合物，由4，4’-二氟二苯甲酮与对苯二酚在二苯砜溶剂中于碱金属碳酸盐作用下进行缩聚反应制得，被广泛用于国防军工、汽车、轮船、航空航天、石油化工、精密仪器制造、整形及骨科领域。
桩核修复：桩核是修复大面积牙体缺损的一种常用的修复方法，桩是插入根管内的部分，利用摩擦力和粘接力等与根管内壁之间获得固位，进而为核提供固位；核固定于桩之上，与牙冠剩余的牙体硬组织一起形成最终的全冠预备体。


背景：聚醚醚酮是具有良好机械性能、生物相容性、化学稳定性的特种塑料聚合物，可加入不同的填料形成新型复合材料，在桩核修复中有潜在的临床应用价值。

目的：综述聚醚醚酮及其复合材料的性能、在桩核修复中的临床应用进展。
方法：以“聚醚醚酮，桩核修复，金属桩，纤维桩，氧化锆桩”为中文检索词检索中国知网数据库，以“PEEK，polyetheretherketone post，post core repair，dental Dowels”为英文检索词检索PubMed数据库，检索时间范围重点为2019年1月至2023年10月。通过阅读文献题目、摘要及全文筛选，根据纳入与排除标准进行筛选，最后纳入71篇文献进行综述。

结果与结论：聚醚醚酮是高性能热塑性聚合物，实验研究证明聚醚醚酮及其复合材料在机械性能、生物相容性、抗老化性、化学稳定性、粘接性能等方面具有优越性，在桩核修复领域应用前景喜人。聚醚醚酮及其复合材料作为桩核修复临床应用局限于前牙和前磨牙，但都获得了满意的修复效果。聚醚醚酮及其复合材料在桩核修复中属于新型材料，目前还有诸多问题尚待解决，如：3D打印设备和打印过程是否会影响材料的机械性能；临床修复效果观察时间短，缺乏长期的研究验证；缺乏聚醚醚酮及其复合材料作为桩核材料修复磨牙的病例报道等，后续还需不断完善相关研究。

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. 

Key words: polyetheretherketone, post core repair, metal posts, fiber posts, composite material, review
