摘要：

目的：分析口腔修复材料的摩擦机制及其影响因素，评价不同口腔修复材料的摩擦性能。
方法：以 “口腔修复材料，陶瓷材料，摩擦性能，耐磨性，影响因素，摩擦机制” 为中文检索词；以“dental materials, ceramics, friction performance，wear，factors，friction mechanism”为英文检索词，采用计算机检索Pubmed数据库(http://www.ncbi.nlm.nih.gov/PubMed)及维普数据库(http://www.cqvip.com/)1993-01/2009-10有关口腔修复材料摩擦性能的文章；排除重复研究、普通综述或Meta分析类文章。以21篇文献为主重点探讨了口腔修复材料的摩擦机制及其影响因素。
结果：理想的口腔修复材料应具备与天然牙近似但又略低于天然牙的摩擦学性能。由于咀嚼过程的复杂性及口腔修复材料的多样性，口腔修复材料的耐磨性受多种因素的影响，因此以口腔陶瓷材料、口腔金属材料、口腔树脂材料为例，了解天然牙与口腔陶瓷材料、口腔金属材料、口腔树脂材料的摩擦磨损特性，选择相匹配的口腔修复材料，能有效防止天然牙过度磨损。                                           

结论：了解口腔陶瓷材料、口腔金属材料、口腔树脂材料等不同口腔修复材料的摩擦磨损性能，既可以帮助医生按照患者的具体情况选择与之相匹配的修复材料，达到最佳修复效果，又有助于开发更合理、更耐磨的口腔修复材料。

Abstract:

OBJECTIVE: To analyze the friction mechanism of dental restorative materials and their influencing factors.
METHODS: Using “dental materials, ceramics, friction properties, wear resistance, influencing factor, friction mechanism” in Chinese and “dental materials, ceramics, friction performance, wear, factors, friction mechanism” in English as the key words, a computer search was performed in Pubmed database (http://www.ncbi.nlm.nih.gov/PubMed) and VIP database (http://www.cqvip.com/) between January 1993 and October 2009 for articles about the friction properties of dental restorative materials; repeated study, review or Meta analysis were excluded. Totally 21 articles mainly focus on the friction mechanism of dental restorative materials and its influencing factors.
RESULTS: The ideal dental restorative materials should have similar with but slightly lower friction properties than natural teeth. As the complexity of chewing process and the diversity of dental restorative materials, the wear resistance of dental materials is affected by many factors, therefore dental ceramic materials, dental metal materials and dental resin materials were investigated to understand the wear properties of natural teeth, dental ceramics materials, dental metal materials, dental resin materials, to select matched dental restorative materials and to prevent excessive wear of natural teeth.
CONCLUSION: An understanding of friction and wear properties of dental restorative materials such as dental ceramic materials, dental metal materials, and dental resin materials, can not only help doctors choose the matching restorative materials according to the individual conditions of patients, achieve the optimal repair results, but also help to develop a more rational, more durable dental restorative material.
