目的
评价Cerec 2计算机辅助设计与制造（CAD/CAM）系统制作的全冠的临床性能。
方法
采用Cerec 2 CAD/CAM全冠修复24颗患牙。修复体植入8年后，采用改良的加州牙科协会质量评价体系对全瓷冠进行评价。患者同时填写满意度调查问卷。并进行Kaplan-Meier分析。
结果
24个修复体中有3个被评为失败。Kaplan-Meier分析显示，Cerec 2冠在分娩后8年的成功率为88%。
结论
Cerec 2 CAD/CAM系统制作的全冠在口腔条件下可存活8年，功能良好。
OBJECTIVE
To evaluate the clinical performance of the crowns made by Cerec2 computer aided design and computer aided manufacture (CAD/CAM) system.
METHODS
Twenty four teeth were restored with Cerec2 CAD/CAM crowns. Eight years after delivery of the prostheses, the all-ceramic crowns were evaluated using modified standard of California Dental Association quality evaluation system. Patients filled out a satisfaction questionnaire at the same time. And Kaplan-Meier analysis was carried out.
RESULTS
Three out of 24 restorations were rated as failure. Kaplan-Meier analysis showed that the success rate of Cerec2 crowns eight year following delivery was 88%.
CONCLUSIONS
Crowns made by Cerec2 CAD/CAM system can survive in oral condition and function well for 8 years.
