Materials used for fixed partial denture (FPD) frameworks have had properties of excellent strength, durability, and biocompatibility. Some of the materials which have been used till date include alloys, ceramics, and high-performance polymers such as zirconia, Ni-Cr, lithium disilicate, and so on. All these, though excellent, have their advantages and disadvantages. Hence, the search has always been on for a better material. One such material, which has made its foray into dentistry in the recent times, is polyetheretherketone (PEEK). It is a semicrystalline thermoplastic material. PEEK has an excellent chemical resistance and mechanical properties that are retained at high temperatures. The versatility of PEEK as a dental material for FPD framework was evaluated in this case report.
用于固定局部义齿（FPD）支架的材料具有优异的强度、耐久性和生物相容性。迄今为止使用过的一些材料包括合金、陶瓷以及高性能聚合物，如氧化锆、镍铬合金、二硅酸锂等。所有这些材料虽然都很出色，但都有其优缺点。因此，一直在寻找更好的材料。聚醚醚酮（PEEK）就是近年来进入牙科领域的一种这样的材料。它是一种半结晶热塑性材料。PEEK具有出色的耐化学性和在高温下仍能保持的机械性能。本病例报告评估了PEEK作为FPD支架牙科材料的多功能性。
