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.
聚醚醚酮（PEEK）已广泛应用于固定义齿修复，包括全冠、固定局部义齿和桩核。与传统材料相比，PEEK优异的机械性能有助于更好地分散应力，从而保护基牙。然而，PEEK的刚度不足，可通过纤维增强来改善。PEEK具有生物相容性，无致突变性、无细胞毒性且无致敏性。然而，PEEK的化学稳定性是一把双刃剑。一方面，PEEK不可降解，口腔内腐蚀最小化；另一方面，其惰性表面使粘结困难。人们已经探索了许多改善PEEK粘结性能的策略，包括酸蚀、等离子体处理、空气颗粒研磨、激光处理和粘结系统。
