目的探讨不同的口腔修复材料的摩擦性能及影响其性能的因素。方法回顾性分析我院修复科2013年1月~2015年1月收治的行口腔修复的患者90例,按使用的修复材料不同分为树脂组、金属组和陶瓷组,各30例,对比3组患者的牙齿修复后的各项情况。结果树脂组牙齿松动脱落例数、金属组牙龈出血和牙周炎例数、全瓷组破碎例数均分别高于另外两组(P<0.05)。结论牙齿修复材料中摩擦性能最好的是金属材料,其次为全瓷材料,树脂材料较差,多种因素都影响其耐磨性。
Objective To study the frictional properties of different dental prostheses and the factors influencing their performance. Methods A retrospective analysis of 90 cases of oral repair in our hospital from January 2013 to January 2015 were divided into resin group, metal group and ceramic group according to the different repair materials used, 30 cases in each group, compared with 3 Group of patients after the restoration of the teeth of the situation. Results The number of teeth loosened off in the resin group, the number of gingival bleeding in the metal group, the number of periodontitis cases and the number of broken cases in all-ceramic group were all higher than those in the other two groups (P <0.05). Conclusion The best frictional properties of dental restoration materials are metal materials, followed by all-ceramic materials, the resin material is poor, a variety of factors affect the wear resistance.
