摘　　要：目的观察计算机辅助设计与制作(CAD/CAM)全瓷冠和全瓷高嵌体修复大面积缺损后牙的临床效果。方法选取2017年11月至2018年5月在郑州大学第一附属医院口腔医学中心就诊的92例(106颗牙残冠)患者,按治疗方法分为A组、B组,A组接受传统桩核全瓷冠修复,B组接受高嵌体修复,两组都选用CAD/CAM方法制作修复体。分别于治疗后3个月和1 a复查修复体修复效果,记录患者满意度。结果两组治疗后3个月和1 a修复优良率比较,差异无统计学意义(均P>0.05)。在治疗后3个月和1 a时,A组和B组修复优良率比较,差异无统计学意义(均P>0.05)。两组治疗后3个月时满意度比较,差异无统计学意义(P>0.05),A组治疗后1 a时满意度差于B组,差异有统计学意义(P<0.05)。A组治疗后3个月满意度优于治疗后1 a,差异有统计学意义(P<0.05),而治疗后3个月和1 a时B组满意度比较,差异无统计学意义(P>0.05)。结论全瓷冠和全瓷高嵌体在修复大面积牙体缺损时均能够取得良好的效果,嵌体磨除牙体组织少,临床操作更简单,使患者具有更好的就诊体验。Objective To observe the effect of CAD/CAM all-porcelain crowns and inlays on the repair of large defect molarteeth.Methods A total of 92 patients(106 dental crowns)were selected from November 2017 to May 2018 in the Stomatology Center of the First Affiliated Hospital of Zhengzhou University.They were divided into two groups according to the treatment methods.Group A received traditional post-core all-porcelain crowns restoration,while group B received inlays restoration,and CAD/CAM method was used to make prostheses in both two groups.The repair results of the prosthesis were reviewed 3 months and 1 year after treatment,and the patients’satisfaction was recorded.Results There was no statistically difference in the repair effect between the two groups 3 months and 1 year after treatment(both P>0.05).Three months and 1 year after treatment,no statistically difference in the repair effect was found in group A and group B(both P>0.05).There was no statistically difference in the satisfaction between group A and group B 3 months after treatment(P>0.05).The satisfaction of group A was worse than that of group B 1 year after treatment,the difference was statistical(P<0.05).The satisfaction of group A 3 months after treatment was better than that 1 year after treatment,and the difference was statistical(P<0.05).The satisfaction 3 months and 1 year after treatment in group B showed no statistical difference(P>0.05).Conclusion All-ceramic crowns and all-ceramic inlays can achieve good results in repairing large-area tooth defects.Inlays have less tooth tissue and simple clinical operation,which makes patients have a better experience.
