口腔修复中不同修复材料的抗摩擦性能分析

Analysis on friction properties of different repair materials in prosthodontics

目的对口腔修复中不同修复材料的抗摩擦性能进行对比分析。方法选取本院的108颗需要修复的牙齿,随机分成3组,每组36例,金属组采用金属材料进行修复;采陶瓷组用陶瓷材料修复;树脂组采用树脂材料修复。对3组牙齿的修复效果进行分析。结果在修复6个月之后,金属组和树脂组的成功率均为94.4%,大于陶瓷组的91.7%,在修复12个月之后,树脂组的成功率为91.7%,大于金属组和陶瓷组的88.9%,3组比较,差异无统计学意义(P>0.05)。结论三种口腔修复材料的抗摩擦性能没有明显差异,在口腔修复过程中均可得到良好的修复效果。

Objective To analyze the friction properties of different repair materials in prosthodontics. Methods 108 teeth that needed repairing in our hospital were selected, they were randomly divided into three groups, 36 cases in each group, one group was given metallic materials treatment, called the metal group; another group ceramic materials treatment, called ceramic group; the last group resin material treatment, called resin group. Then analyzed the repair effect of the three groups of teeth. Results 6 months later, compared to ceramics group （91.7%）, the success rate of metal and resin group （94.4%） were higher; and 12 months later, compared to metal and ceramic group （88.9%）, the success rate of resin group（91.7%） was higher. The difference between the three groups was not statistically significant （P 0.05）. Conclusion The anti wear property differences between the the three kinds of dental materials are not significant, they all can obtain good effect in the oral cavity repair process.
