Abstract：AIM:To evaluate the clinical performance of IPS e.max CAD ceramic restorations and to analyze the reason of failure.METHODS:255 IPS e.max CAD ceramic restorations were made by CEREC AC for 215 patients.All the restorations were evaluated at 3,6 and 12 m follow-up using the modified United StatesPublic Health Standard(USPHS).The cumulative survival rate (CSR) of the restorations was calculated and the related influence factors such as restoration type and tooth region were analyzed by Kaplan-Meier survival analysis and Log-Rank test.RESULTS:During the observation period,chipping or fracture was observed in 8 restorations,and debonding in 5 restorations.The 1-year cumulative survival rate (CSR) of the restorations was 96.5%.The difference of the corelation of the CSR with restoration types,or with tooth region was not statistically significant (P>0.05).96% of the restorations were classified as A by USPHS.The performance in marginal adaptation,color match and secondary caries resistance was outstanding.CONCLUSION:IPS e.max CAD all-ceramic restorations made by CEREC AC demonstrate good clinical results within 1year observation.
