聚醚醚酮(PEEK)在固定牙修复中得到了广泛的应用,包括皇冠,固定局部义齿,和后核心。PEEK优异的机械性能比传统材料有利于更好的应力分布,保护基牙。然而,PEEK的刚度不足,这可以通过纤维增强进行改进。PEEK是生物相容的。它是非诱变的,非细胞毒性,和非过敏性。然而,PEEK的化学稳定性是一把双刃剑。一方面,PEEK是不可降解的,并且口腔内腐蚀最小化。另一方面,惰性表面使粘合剂粘合困难。已经探索了许多改善PEEK粘合性能的策略,包括酸蚀,等离子体处理,空气中的颗粒磨损,激光治疗,和粘合剂系统。
Polyetheretherketone (PEEK) has been widely applied in fixed dental prostheses, comprising crowns, fixed partial dentures, and post-and-core. PEEK\'s excellent mechanical properties facilitate better stress distribution than conventional materials, protecting the abutment teeth. However, the stiffness of PEEK is not sufficient, which can be improved via fiber reinforcement. PEEK is biocompatible. It is nonmutagenic, noncytotoxic, and nonallergenic. However, the chemical stability of PEEK is a double-edged sword. On the one hand, PEEK is nondegradable and intraoral corrosion is minimized. On the other hand, the inert surface makes adhesive bonding difficult. Numerous strategies for improving the adhesive properties of PEEK have been explored, including acid etching, plasma treatment, airborne particle abrasion, laser treatment, and adhesive systems.
