摘　　要：目的观察复合树脂嵌体修复后牙缺损3年后的临床疗效。方法选择160例后牙牙体缺损的患牙按分层随机法分为2组,每组80颗患牙。试验组采用复合树脂嵌体修复后牙牙体缺损,对照组复合树脂传统直接充填修复。以改良USPHS评价方法为疗效评价手段,追踪3年,比较2组修复方法的相关性。用SPSS12.0软件进行χ2检验。结果术后3年共10例患牙接受复查,其中嵌体组76颗,成功率为96.1%,χ2检验2组成功率的差异有统计学意义(P<0.05)。结论复合树脂嵌体修复后牙缺损能的远期临床疗效优于传统复合树脂直接充填。Objective The aim of this study was to present an 3-year assessment of indirect resin composite inlays.Methods A total of 160 defective posterior teeth was divided into two groups,including 80 teeth of each. One group was restored with the indirect inlays and another group with conventional composite restorations. The restorations were evaluated clinically,according to modified USPHS criteria.All the figures was analyzed using χ^2-test with SPSS 12.0 software package.Results Of the 76 inlays and 74 conventional restorations evaluated at 3 years,96.1% in the inlay group was assessed as acceptable. The differences in longevity were statistically significant（P〈0.05）.Conclusion The difference was observed between the inlays and conventional composite restorations.A higher failure rate was found in conventional composite restorations than the inlays.
