目的：对比分析CAD/CAM全瓷嵌体与复合树脂嵌体修复后牙Ⅱ类洞的临床疗效。方法：选择在解放军总医院口腔内科就诊的后牙Ⅱ类洞患者193例(共226颗牙)，根据患者意愿，其中101颗采用CAD/CAM全瓷嵌体修复，其余125颗采用复合树脂嵌体修复，分别在术后6个月、12个月、18个月进行随访，观察其修复体磨耗、折裂、脱落、边缘密合性、边缘着色及继发龋等情况。结果：2种嵌体在修复体磨耗及边缘着色的差异有统计学意义(P＜0.05)，在修复体折裂、修复体脱落、继发龋和边缘密合性的差异无统计学意义(P＞0.05)。 CAD/CAM 全瓷嵌体的成功率为：96.84%，树脂嵌体的成功率为：81.05%，两组之间成功率的差异有统计学意义(P＜0.05)。结论：在后牙Ⅱ类洞缺损的修复治疗中， CAD/CAM全瓷嵌体的效果优于复合树脂嵌体。

Objective:To compare the clinical efficacy of CAD/CAM all-ceramic inlay and composite resin inlay in restoring ClassⅡcavity of posterior teeth. Methods:226 posterior teeth of ClassⅡcavity from 193 patients were recruited in our clinical trial. 101 teeth of the selected teeth were restored with CAD/CAM all-ceramic inlays, and the rest was restored by composite resin inlays. Prosthesis abrasion, prosthesis fracture, prosthesis off, marginal adapta-tion, edge coloring, and secondary caries of the two groups were evaluated during 6-month, 12-month and 18-month follow-up appointments, respectively. Results: There were significant differences in prosthesis abrasion and edge coloring between the two groups (P<0.05), but no significant difference was observed in prosthesis off, prosthesis fracture, marginal adaptation, and secondary caries (P>0.05). The success rate of CAD/CAM all-ceramic inlay is 96.84%, and the composite resin inlay is 81.05%. There was significant difference between the success rates (P<0.05). Conclusion:The efficacy of CAD/CAM all-ceramic inlay is better than that of composite resin inlay during the treatment of the posterior ClassⅡcavities.
