摘要
目的:探讨CAD/CAM二氧化锆全瓷冠在牙体缺损修复中的应用。方法:选择58例患者96颗患牙,采用CAD/CAM二氧化锆全瓷冠修复,观察3年。结果:96颗二氧化锆全瓷冠在修复完成3年后复查,1个全瓷冠使用1年后饰面瓷出现崩瓷,其余修复体的颜色、形态、边缘着色、边缘密合度、各项检查达到A级。结论:CAD/CAM二氧化锆全瓷冠在牙体缺损修复中的临床应用效果良好。
Objective: To investigate the clinical results of zirconia crown manufac- tured by CAD/CAM in the restoration of de- fected teeth. Methods:ALL 58 patients trea- ted with porcelain -veneered zirconia single crowns for 96 defected teeth. After 36 months follow up. Results: Through three years clinical observations, only 1 case ap- peared porcelain dropped, the other, restora- tions are scored A in color, shape, margin coloring, margin sealing and second caries. Conclusion:The clinical effect was satisfac- tory of zirconia crown manufactured by CAD/CAM.
