摘　　要：聚醚醚酮是一种具有良好的力学性能、化学稳定性以及生物相容性的特级工程塑料。目前聚醚醚酮在全口义齿、可摘局部义齿等口腔修复领域得到了广泛应用。相关实验研究表明聚醚醚酮桩优于玻璃纤维桩,具有良好的粘接强度以及抗折性能。目前相关聚醚醚酮桩核冠修复病例报道较少,已有相关临床病例报道表明聚醚醚酮桩核修复效果良好,美学性能优异,可视为理想的桩核材料。对于聚醚醚酮桩的制取方式及表面处理的方法需要进一步优化。本文就聚醚醚酮作为口腔材料的性能及在桩核冠系统领域的应用前景进行综述。Polyetheretherketone(PEEK)is known as a high-grade engineering plastic with good mechanical properties,chemical stability and biocompatibility.Currently,PEEK materials have been widely used in prosthodontics,such as complete dentures and removable partial dentures.The relevant research shows that PEEK posts are superior to glass fiber posts,which have high tensile bond strength and bending strength.At present,few case reports of PEEK postcores have been published,and clinical case reports suggest that PEEK postcores have good oral prosthetic aesthetics and are ideal and reliable postcore crown materials.However,the preparation and surface treatment methods of PEEK require further refinement.A review of the related properties of PEEK and the prospects of its application in the field of postcore crown restoration will be presented in this paper.
