摘    要:目的 观察CAD/CAM全瓷髓高嵌体在牙体缺损中的临床效果。方法 选择71例病例(患牙82颗),其中男33例,女38例,年龄20~50岁,均采用IPS e.max CAD全瓷髓高嵌体进行后牙修复。随访24个月,观察修复体的颜色、形态、折裂、边缘密合度、基牙继发龋及邻接食物嵌塞的情况。结果 82颗修复体即刻满意度在85%以上。随访24个月中,失访4颗,78颗修复体形态和基牙继发龋方面均达到A级标准。1颗修复体轻微折裂,4颗出现邻接食物嵌塞,95%以上的修复体均达 A 级。结论 IPS e.max CAD全瓷髓高嵌体用于根管治疗的后牙短期修复效果良好。

Clinical evaluation of CAD/CAM ceramic Endo-onlay restoration in the posterior teeth after root canal treatment
Abstract:Objective  To evaluate clinical effects of CAD/CAM ceramic Endo-onlay restoration in the posterior teeth after root canal treatment. Methods 82 completed endodontically treated posterior teeth from 71 cases, including 33 males and 38 females, aged 20-50 years old, were restored with IPS e.max CAD Endo-onlays.Then the color, shape, fracture , marginal discrepancy, secondary caries and food impaction status were assessed after a 24-month follow-up.Results During the follow-up, 4 were missing among 82 dental restorations, among which 78 met the class A standards for shape and secondary caries. 1 was fractured and 4 appeared to have food impaction, more than 95% were scored grade A. Conclusion CAD/CAM ceramic Endo-onlay has good clinical effect in restoration of endodontically treated posterior teeth.
Keywords:CAD/CAM  IPS e.max CAD Endo-onlay  posterior teeth  Tooth Defect
