Abstract:
Failure-time analysis of Dicor single crown restorations: Statistical methods of survival-analysis according to Kaplan-Meier were applied to investigate the effects of the fracture of 159 Dicor-restorations in 82 patients in a private dental office. After 33 months of service 77% (+/- 15%; 95% Conf. Int. for the mean) of the crowns were still under risk. Fractures were very high in molar crowns.
