摘要：

目的    探讨CEREC AC全瓷高嵌体微创修复后牙残冠的临床效果。方法    对2014年7月至2015年7月于解放军第四六三医院口腔科就诊的66例后牙残冠（84颗患牙）经根管治疗后需修复患者，采用CEREC AC 椅旁即刻全瓷修复系统制作全瓷高嵌体一次法完成修复，分别于修复后3、6、12个月预约复诊观察，按照改良美国公共健康协会（USPHS）标准对修复体进行评价。结果    通过12个月的随访观察，66例患者的84件高嵌体修复体无一脱落，固位效果达100%。除1件修复体发生折裂外，其余修复体各检查项目的评价均达到了B级标准。结论    CEREC AC全瓷高嵌体微创修复后牙残冠短期效果良好。
