摘要：

聚醚醚酮（PEEK）为线性芳香族高分子化合物,自面世以来,凭借其卓越的力学性能和化学稳定性,广泛应用于航空航天、汽车制造以及精密仪器制造等高科技领域。此外,PEEK材料可靠的生物安全性、适宜的弹性模量、良好的表面性能等特性使得其在医学领域也得到了广泛应用。目前,PEEK在口腔医学领域中的应用正逐渐增多,如作为种植体、临时基台、固定及可摘义齿材料等越来越引起学者的关注。本文就PEEK材料在口腔种植与修复领域的研究进展作一综述。

关键词: 聚醚醚酮, 种植体, 骨整合, 固定义齿, 可摘局部义齿

Abstract:

Polyetheretherketone (PEEK) is a linear aromatic polymer with excellent mechanical properties and chemical stability. PEEK has been widely used in aerospace, automobile and precision instrument manufacturing, and other high-tech fields. In addition, the reliable bio-safety, suitable elastic modulus, and good surface properties of PEEK materials have made it widely used in the medical field. Currently, the application of PEEK and its attraction among scholars are gradually increasing in stomatology applications, such as implants, temporary abutment, and fixed and removable denture materials. In this article, the research progress of PEEK on oral implantology and prosthodontics is reviewed.

Key words: polyetheretherketone, implant, osseointegration, fixed partial denture, removable partial denture
