　　目的：研究CAD/CAM全氧化锆嵌体在牙体中应用的相关问题。方法：对32颗修复的全氧化锆嵌体病例进行临床分析并随访。结果：随访1年，1例在粘结后1个月出现嵌体脱落，经过重新备洞并再次粘结后，随访至今未再脱落，粘结后总的稳固率为96.88%(31/32)；敏感发生率为9.38%(3/32)，敏感症状半年后逐渐自动消失；无嵌体折裂和继发龋出现。32颗修复体从形态、美观、色泽、边缘密合度、患者满意度等方面均达到满意效果。结论：严把技术关，精细操作，采用合适的粘结材料，掌握一定的全瓷粘结技巧，CAD/CAM全氧化锆嵌体可在牙体修复中取得较为满意的效果。

Objective:To study on the application of CAD/CAM Zirconia Inlay in the reconstruction of teeth.Methods:The reconstructed teeth of 32 cases of Zirconia Inlay were analysed of and followed-up.Results:During one year’s follow-up,there was one case that the inlay came out a month after bonding, and after a second cavity preparation and bonding,it had not dropped again up to now.The overall stable rate was 96.88%(31/32) after the second bonding.The occurrence of hypersensitivity was 9.38%(3/32) and the hypersensitivity disappears gradually half a year later.No inlay jackknifing or secondary caries occurred.All of the 32 restorations were satisfying in shape,color and luster,marginal fit,patients’ satisfaction degree.Conclusion:With strict technology,fine operation, proper bonding materials and certain skills of all-ceramic bonding,CAD/CAM Zirconia Inlay can reach satisfactory clinical results on the reconstruction of teeth.
