Abstract:
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.
