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。

Abstract:

Objective　To evaluate clinical effects of indirect polymerid porcelain inlay on massive defect of vital pulp posterior teeth.　Methods　From 2008 January to 2010 March, 31massive defect vital pulp posterior teeth were restored with Ceramage 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.　Conclusion 　Massive defect of vital pulp posterior teeth can be well restored with the indirect polymerid porcelain inlays. It indicates indirect polymerid porcelain inlay used for massive defect of vital pulp posterior teeth have stable Clinical effects.
