A longitudinal study of the clinical performance of porcelain veneers.
A total of 315 porcelain labial veneers were fitted in 96 patients in two teaching hospitals, between July 1986 and October 1991, and were evaluated after a period of up to 63 months. During the evaluation period 53 (17%) restorations in 31 (32%) patients presented with a problem at review. Of these, 25 (8%) were of a minor nature and the veneer remained in use while 34 (11%) debonded or were removed. Increased problem and failure rates were associated with veneers placed on existing restorations, where tooth surface loss had occurred prior to treatment, and where inappropriate luting agents were employed. Age, gender, fabrication technique (platinum foil or refractory die), use of rubber dam and year of bonding were not significant factors.
