摘　　要：目的:观察间接法复合树脂嵌体修复磨牙大面积牙体缺损的临床疗效。方法:针对磨牙大面积牙体缺损分别采用间接法复合树脂嵌体技术和复合树脂直接充填修复,每组100例,两年后随访观察,评价标准采用USPHS评价标准,分别从边缘着色、边缘密合度、解剖形态、基牙继发龋、修复体折裂进行评价。结果:复合树脂嵌体修复2年后成功率明显优于复合树脂直接充填(P<0.05)。实验组4例缺陷,主要为边缘着色,边缘完整性破坏,1例失败为折裂;对照组10例缺陷,主要为边缘着色,边缘完整性破坏,磨损,邻接不良;6例失败,其中2例继发龋,4例折裂。结论:间接法复合树脂嵌体修复后牙大面积牙体缺损具有一定优越性,临床疗效良好。Objective To evaluate clinical effects of indirect composite resin inlay restoration on massive destruction in molar.Methods Massive destruction in molar were divided into two groups： 100 in indirect composite resin inlays group and 100 in control group （composite resin）.The clinical effects of indirect composite resin inlay and composite resin in posterior teeth were compared in USPHS criterion （marginal discoloration, marginal adaption, secondary caries, anatomic shape integrity and fractures of tooth）2 years later. Results 2 years after treatment, the successful rate of indirect composite resin inlays was 94.62% （88/93）.The corresponding figure for composite resin was 82.22% （74/90）.The difference was statistically significant difference.（P〈0.05）. Conclusion Massive destruction in molar can be well restored with the indirect composite resin inlay. Clinical effects of indirect composite resin inlay are superior to those of composite resin in two years.
