摘　　要：目的:分析CAD/CAM高嵌体修复磨牙根管治疗后牙冠大面积缺损的疗效分析。方法:选择260颗牙体重度龋损累及牙髓的磨牙,经完善的根管治疗后采用CAD/CAM椅旁技术进行全瓷高嵌体修复。分别在修复后6、12、18个月进行随访,参考美国公共健康会(USPHS)标准对其临床效果进行观察。结果:在260颗患牙中,CAD/CAM高嵌体修复磨牙根管治疗后牙冠大面积缺损成功率为98%,其中3例发生修复体脱落,2例发生修复体折裂。结论:CAD/CAM高嵌体修复技术可以作为磨牙根管治疗后牙体大面积缺损修复的手段。Objective： To observe the clinical efficacy of CAD/CAM all-ceramic onlay in the restoration of molars with extensive defect after root canal therapy （RCT）. Methods： 260 molars with extensive defect were restored by all-ceramic onlay after RCT. The pa- tients were followed up for 18 months. Tile restoration effects were assessed using USPHS criteria. Results： The success rate of CAD/ CAM all-ceramic onlay was 98%. Restoration exfoliation was found in 3 cases, fractured in 2 cases. Conclusion： CAD/CAM all-ce- ramic onlay can be applied in restoring extensive postenor tooth-defection after RCT.
