摘　　要：目的:研究CAD/CAM玻璃瓷高嵌体修复根管治疗后下颌第二磨牙的临床疗效。方法:选择56颗远中龋坏的下颌第二磨牙,进行一次性根管治疗,1周后用CAD/CAM玻璃瓷高嵌体修复,嘱患者治疗后每6个月复诊1次,运用USPHS标准进行临床效果评价。结果:全部患牙经过2年复查,在嵌体固位、边缘密合性、颜色匹配性、继发龋、邻接关系等方面性能良好,仅3例失败:2例嵌体脱落,1例发生崩瓷。结论:CAD/CAM玻璃瓷高嵌体是下颌第二磨牙远中龋坏根管治疗后的有效修复方法,值得在临床推广。Objective： To evaluate the clinical effects of CAD/CAM glass-ceramic onlays in the restoration of mandibular second molar with distal caries. Methods： 56 endodontically treated molars were restored with CAD/CAM glass-ceramic onlays after one-visit root canal treatment. The effects were evaluated by one experienced clinicians in accordanced with the modified USPHS-Criteria at baseline and after 6,12 18 and 24 months. Results： All teeth were completed 2-year-follow-up. Satisfactory effects were observed in retention, marginal adaptation, color match, the secondary caries and adjacency relation. Failure in 3 cases were noted. 2 onlays were extracted and 1 fractured. Conclusion： CAD/CAM glass-ceramic onlays is an effective treatment in the restoration of permanent molars with serious caries.
