CEREC 3D瓷嵌体治疗后牙邻面缺损所致食物嵌塞的疗效评价

Clinical evaluation of molar food impaction for proximal teeth defect with CEREC 3D ceramic inlay

目的:探讨CEREC 3D瓷嵌体治疗牙体缺损所致食物嵌塞的临床效果。方法:收集后牙邻面缺损致食物嵌塞112例130颗牙,将患者分为3组:CEREC 3D嵌体组57颗牙,金合金嵌体组11颗牙,玻璃离子充填组62颗牙;1年后观察临床疗效,检查记录修复体折断、脱落、食物嵌塞、牙龈炎、继发龋情况,对3组结果采用卡方检验进行统计分析。结果:CEREC 3D嵌体除2例发生折断外无其他并发症,成功率96.43%,其在抗修复体脱落、食物嵌塞、龈炎、继发龋等方面与金合金嵌体差异无显著性(P>0.05),但明显优于玻璃离子充填(P<0.05)。结论:邻面缺损需恢复邻接关系的食物嵌塞病例,CEREC 3D嵌体有明显优势。

Objective： To evaluate the clinical effect of CEREC3D inlay on food impaction in molar caused by dental defect.Methods： One hundred and thirty teeth with food impaction in molar caused by proximal defect in 112 patients were divided into three groups,57 teeth in CEREC 3D inlay group,11 teeth in gold alloy inlay group,62 teeth in glass ionomer filling group.Clinical effects of restoration fracture,restoration loss,food impaction,gingivitis,secondary caries were evaluated after 1 year and analyzed with Chi-square test.Results： Two inlays were fractured in CEREC 3D inlay group with success rate 96.43%.According torestoration loss,food impaction,gingivitis,secondary caries,there was no significant difference between CEREC 3D inlay group and gold alloy inlay group（P0.05）,but CEREC 3D inlay group showed superiority than glass ionomer filling group（P0.05）.Conclusion： CEREC 3D inlay might be a better restoration for proximal defect and a promising prospect in food impaction treatment.
