摘要
介绍了金属、陶瓷等传统口腔生物材料的优势与不足,聚醚醚酮(PEEK)在口腔医学领域应用的突出优势(卓越的理化性能、良好的生物兼容性及美观性).综述了PEEK在口腔正畸(正畸弓丝、早期矫治器械和舌侧固定保持器)、口腔修复(冠修复体、桩核、固定局部义齿、可摘局部义齿及颌面赝复体)、口腔种植(口腔种植体、愈合基台和骨支架)、口腔颌面外科(颌骨和颞下颌关节重建)及牙周病学(牙周夹板和牙合垫)等多个领域的应用现状、存在的不足和面临的挑战.重点讨论了通过PEEK改性以提升其在临床应用中的性能和适用性的多种方法.最后对PEEK在口腔医学领域的未来应用前景和发展方向进行了展望.
Abstract
The advantages and shortcomings of traditional dental biomaterials such as metals and ceramics,and the remark-able advantages of polyetheretherketone(PEEK)which possess excellent physical and chemical properties,good biocompatibility and aesthetics in the field of stomatology were introduced.The application status,disadvantages and challenges of PEEK in ortho-dontics(orthodontic archwires,early appliances,and fixed lingual retainer),prosthodontics(crown restoration,post-core,fixed partial denture,removable partial denture,and maxillofacial prosthesis),oral implantology(dental implant,healing abutment,and bone scaffold),oral and maxillofacial surgery(jaw reconstruction,temporomandibular joint reconstruction),and periodontics(peri-odontal splint and occlusal splint)were reviewed.Various methods of PEEK modification to improve its performance and applicabil-ity in clinical applications were discussed.Finally,the future application prospect and development direction of PEEK in the field of stomatology were also prospected.
