[摘要]瓷贴面修复因具有外形美观、颜色协调、可修补和更换、磨除牙体少等优点而被越来越广泛地应用于临床修复中。瓷贴面修复的最终临床效果受多种因素的影响，其中，牙体预备方式直接关系到修复后的美观效果和成功率，牙体预备被认为是瓷贴面修复获得良好临床效果的重要保证之一。本文就瓷贴面牙体预备的分型、不同牙体预备对瓷贴面力学性能和临床修复效果的影响进行综述，以期为临床工作中选择正确的牙体预备方式进行瓷贴面修复提供一定的参考依据。

    Effect of mechanical function and clinical results of porcelain laminate restoration based on different tooth preparation designsLiu Jingying, Liu Xiaoming.(The Second Departtment of Prosthodontics, Tianjin Stomatological Hospital, Tianjin 300041, China)

    [Abstract]Because of the esthetic appeal, biocompatibility and adherence to the physiology of minimal-invasive dentistry, porcelain laminate veneers have now become a restoration of choice. The ultimate clinical results of porcelain laminate veneers could be affected by many factors, and the type of preparation designs was straightly related to the esthetic effect and the final achievement ratio. The type of preparation designs was one of the important warrants for good clinic results. The paper reviewed the types and the effects of preparation to the mechanical function and restoration results of porcelain veneers, in order to provide references for clinic applications. ......
