摘　　要：目的:评价咬合面无饰瓷氧化锆后牙单冠的临床效果。方法:本研究选取96例患者的单颗后牙的治疗后全冠修复,96颗后牙全部选择咬合面无饰瓷氧化锆全冠,经过3年随访,对修复体本身、对颌牙釉质磨耗情况以及患者满意度进行临床疗效评价,评价结果采用秩和检验。结果:96例修复体除2例出现修复体脱落现象以外,在修复体抗折性、边缘适合性、邻接关系方面均未发生改变,同时对颌牙磨耗的分级评价未发生显著改变改变,经检验未见统计学差异。结论:无饰面氧化锆后牙单冠进行3年观察能够满足临床治疗需要。Objective To evaluate the clinical effects of Zirconia Single Crown with no-covered by Ceramics. Methods 96 posterior teeth was received the restorations by Zirconia Single Crown which uncovered by low fusing porcelain at the side of occlusion.During the three-year follow-up period,clinical events,including fracture and loss of retention,marginal integrity and wear of opposite natural teeth were recorded and calculated. Results Two of the zirconia prostheses lost retention and were re-cemented,but didn＇t exist significant difference（P 0.05）.And no fracture,secondary caries or excessive wear of opposite teeth were reported. Conclusion Zirconia Single Crow with no-covered by ceramics can be used in restorations of posterior single tooth in 3 years.
