目的探讨分析金属、树脂、陶瓷三种口腔修复材料的摩擦性能。方法收集2015年3月—2016年3月该院收治的牙体缺损患者90例，通过随机数表法分为A组、B组、C组各30例，三组患者选择不同的材料进行修复。给予A组患者树脂材料修复，给予B组患者金属材料修复，给予C组患者釉质瓷修复。进行1年的随访，观察比较三组患者修复成功情况的情况。结果A组修复6个月后成功率为96.67%，修复1年后成功率为86.67%；B组修复6个月后成功率为90.00%，修复1年后成功率为83.33%；C组修复6个月后成功率为96.67%，修复1年后成功率为90.00%。三组患者修复6个月后成功率及修复1年后成功率差异均无统计学意义（P＞0.05）。结论金属、树脂、陶瓷三种口腔修复材料均有较好的抗磨檫性能，均可作为口腔修复材料。

［Abstract］Objective To study the analysis of the metal，resin，ceramic friction performance of three kinds of oral repair material.Methods Collected from March 2015 to March 2016 of our hospital，90 cases of patients with tooth defect，through the stochastic indicator method is divided into group A and group B，group C each 30 cases，three groups of patients to select different materials for repair.Give patients of group A resin material to fix，group B patients' repair metal materials，to give the patients of group C enamel porcelain restoration.1 year of follow-up，observed repair success compare three groups of patients.Results The group A repair six months after success rate was 96.67%，1 year after repair success rate is 86.67%；Group B six months after repair success rate was 90.00%，1 year after repair success rate is 83.33%；Group C repair six months after success rate was 96.67%，repair success rate was 90.00%by year's end. Three groups of patients 1 year after repair success rate and six months after repair success rate differences had no statistical significance（P＞0.05）.Conclusion Metal，resin，ceramics three oral repair material all have good anti-wear performance of polishing，all can be used as dental restorative materials.

口腔材料学的进步与发展，越来越多的口腔修复材料应用于临床中。部分牙科患者存在牙齿缺损或病变程度较为严重，需要采用口腔修复材料进行修复，因此口腔修复材料的性能直接会影响修复后牙齿的功能及使用寿命［1］。口腔修复材料长期处于口腔中，正常的咀嚼食物会使口腔修复材料磨损，同时湿润的口腔环境也会加速口腔材料的磨损，因此临床中应选择抗摩擦性能好的替代材料［2-3］。常见的口腔修复材料主要有金属、树脂、陶瓷三种，三种材料在临床中各具优势。……
