摘　　要：目的研究活髓后牙大面积牙体缺损,保存活髓使用聚合瓷嵌体间接修复的临床疗效。方法 2008年1月—2010年3月临床活髓后牙大面积牙体缺损患者28例患牙31颗,牙体预备,Ceramage聚合瓷嵌体间接修复,RelyX Unicem树脂粘接剂粘接随诊2年,以修正的USPHS标准评价修复后2年的随访。结果聚合瓷嵌体修复体在各个复查阶段均没有出现分级为C的结果,2年的修复成功率为100%。结论聚合瓷嵌体能较大程度保存牙髓活力,精确地恢复牙体形态、邻接关系与咬合关系,降低继发龋的发生,临床修复效果稳定。Objective To evaluate clinical effects of indirect polymerid porcelain inlay on massive defect of vital pulp pos- terior teeth. Methods From 2008 January to 2010 March, 31 massive defect vital pulp posterior teeth were restored with Ce- ramage polymerid porcelain inlays and cemented with RelyX Unicem resin adhensive. The modified USPHS criteria were used to evaluate the treatment effects at recall periods. Follow - up were conducted for two years. Results After 2 years, the success rate was 100%. All of observation items in modified USPHS criteria were above C level at recall periods. Con- clusion Massive defect of vital pulp posterior teeth can be well restored with the indirect polymerid porcelain inlays. It indi- cates indirect polymerid porcelain inlay used for massive defect of vital pulp posterior teeth have stable Clinical effects.
