[Survival rate analysis and clinical follow-up of tooth-colored restorations of CEREC].

A survival rate analysis of 426 CEREC restorations, made in a general dentistry practice, was carried out for a period of 3 years. 12 restorations were lost. Thus the Kaplan-Meier probability of survival decreased to 0.95 within 23 months. The mortality rates of restorations in molars and of restorations in premolars showed no significant difference. The patients assessed the treatment results in 96% of the cases as "good" or very good". In 4 cases chewing sensibility necessitated the reconstruction of the inlay restoration. With increasing observation time a reduced quality of the marginal integrity was found.
