摘　　要：背景:陶瓷材料因具有优良的机械性能、与口腔组织良好的生物相容性及高度美观性广泛应用于口腔修复领域,良好的磨损性能对修复体临床应用有重要意义。目的:综述口腔修复陶瓷材料磨损性能机制及临床研究,以期为临床选择适宜的陶瓷材料提供思路。方法:应用计算机在PubMed和Web of Science数据库检索在2016年1月至2021年4月期间涉及口腔修复陶瓷材料磨损性能的相关研究。英文检索词为“dental ceramic material,wear property”,最终共纳入36篇文献进行分析。结果与结论:①全瓷材料自身耐磨性均高于树脂陶瓷复合材料,全瓷材料中氧化锆陶瓷磨损性能最佳,美学性能较弱。②玻璃陶瓷中氧化锆加强型硅酸锂玻璃陶瓷磨损性能较好,但应用时间较短,长期疗效还有待更多的研究证实。③树脂陶瓷复合材料中树脂纳米陶瓷材料磨损性能优于聚合物渗透陶瓷。④在后牙区全冠修复可选择氧化锆陶瓷,前牙区全冠修复可以根据患者的美学需求选择高透性氧化锆陶瓷或玻璃陶瓷。⑤贴面、嵌体和高嵌体修复可选择长石瓷、玻璃陶瓷和树脂陶瓷复合材料,但树脂陶瓷复合材料耐磨性差,需避免用于高应力承载区。⑥对牙本质暴露、氟斑牙和牙齿酸蚀症患者可考虑树脂纳米陶瓷材料,但这类患者适宜的陶瓷材料相关研究较少。⑦表面粗糙度对陶瓷材料的磨损性能有显著影响,临床口腔修复应用中采用良好的抛光表面可提高陶瓷材料磨损性能,而且对修复体进行定期复查也至关重要。BACKGROUND:Ceramic materials are widely used in the field of prosthodontics because of their excellent mechanical properties,good biocompatibility with oral tissues,and high aesthetic properties.Good wear properties have important clinical significance for prosthodontics.OBJECTIVE:To review the mechanisms and clinical studies on the wear properties of ceramic materials for prosthodontics in order to provide ideas for the clinical selection of suitable ceramic materials.METHODS:A computer search was conducted on PubMed and Web of Science databases for studies involving the wear properties of dental restorative ceramic materials between January 2016 and April 2021.The English search terms were“dental ceramic material;wear property”.Finally,36 articles were included for analysis.RESULTS AND CONCLUSION:(1)The wear resistance of all-ceramic materials was higher than that of resin-ceramic composites.Among the all-ceramic materials,zirconia had the best wear properties and weaker aesthetic properties.(2)Among glass ceramics,zirconia-reinforced lithium silicate glass ceramic has better wear property,but the clinical application time is short,and the long-term efficacy needs more experimental research.(3)Among the resin-ceramic composites,nano-ceramic resin materials have better wear properties than ceramic-polymer.(4)Zirconia can be chosen for full-crown restorations in the posterior region,and high-translucent zirconia ceramics or glass ceramics can be chosen for full-crown restorations in the anterior region,depending on the patient’s aesthetic needs.(5)Veneers,inlays and onlays restorations can be selected from feldspathic porcelain,glass ceramic and resin-ceramic composites,but resin-ceramic composites have poor wear resistance and need to be avoided for high stress bearing areas.(6)Nano-ceramic resin can be considered for patients with exposed dentin,fluorosis and dental erosion,but experimental studies of suitable ceramic materials for these patients are scarce.(7)Surface roughness has a significant effect on
