Clinical follow-up study of ceramic veneered titanium restorations-Three-year results

Eighty-four titanium restorations having 125 ceramic veneers were placed for 32 patients. One hundred sixteen (93%) of the veneers could be reexamined after 21 to 41 months. Two of the restorations required removal because of a partial veneer loss. A Kaplan-Meier survival analysis was performed, giving a survival probability of .85 for single crowns and .59 for fixed partial dentures after a time interval of 30 months, regarding the veneer cracking or chipping. There was a significantly higher survival probability for single crowns than for fixed partial dentures (P = .001, logrank test). It was concluded that ceramic veneered titanium restorations should be limited to single crowns.
