摘要
目的:探究在后牙邻面牙体缺损的修复中应用CAD/CAM全瓷嵌体的临床效果。方法:选取2016年8月-2017年3月于本院接受后牙邻面牙体缺损修复的患者90例作为研究对象,共110颗牙,按照随机数字表法将其分为治疗组(n=50颗)和对照组(n=60颗),各45例。治疗组使用CAD/CAM全瓷嵌体,对照组使用复合树脂,比较两组的修复成功、边缘密合度成功和颜色匹配以及继发龋齿发生情况。结果:治疗组的修复成功率为98.00%,明显高于对照组的81.67%,差异有统计学意义(X^2=7.49,P=0.01)。两组的边缘密合度成功和颜色匹配情况比较,差异均无统计学意义(P>0.05)。两组继发龋齿发生情况比较,差异无统计学意义(X^2=0.92,P=0.34)。结论:在后牙邻面牙体缺损的修复中应用CAD/CAM全瓷嵌体可以改善修复效果,且实用性更强,可将这一修复材料进行推广。
Objective：To explore the clinical effect of CAD/CAM all ceramic inlay in the repair of approximal surface dental defect of posterior teeth.Method：A total of 90 patients with posterior approximal surface dental defect repair and 110 tooth admitted from August 2016 to March 2017 in our hospital were selected as the study objects,according to the random number table method,they were divided into treatment group（n=50 tooth）and control group（n=60 tooth）,45 cases in each group.The treatment group was used CAD/CAM all ceramic inlay,the control group was used composite resin.The success of repair,the success of edge consistency,color matching and the incidence of secondary caries were compared between the two groups.Result：The success rate of repair in the treatment group was 98.00%,which was significantly higher than 81.67% in the control group,the difference was statistically significant（X^2=7.49,P=0.01）.There were no significant differences in the success of edge consistency and color matching between the two groups（P〉0.05）. There was no significant difference in the incidence of secondary caries between the two groups（X^2=0.92,P=0.34）.Conclusion：The application of CAD/CAM all ceramic inlay can improve the effect of restoration in the repair of Posterior approximal surface dental defect and is more practical,which can promote this repair material.
