title: Porcelain laminate veneers: 6- to 12-year clinical evaluation--a retrospective study.
abstract: The purpose of this study was to retrospectively evaluate the clinical performance of laminate veneers placed in the anterior segments of the dental arches over a 12-year period at two different private dental practices. Forty-six patients were restored with 182 porcelain laminate veneers. The veneers were studied for a mean observation time of 5.69 years. Color match, porcelain surface, marginal discoloration, and marginal integrity were clinically examined following modified CDA/Ryge criteria. On the basis of the criteria used, most of the veneers rated A. Risk of fracture was determined with a Kaplan-Meier survival analysis. Probability of survival of the 182 veneers was 94.4% at 12 years, with a low clinical failure rate (approximately 5.6%). Porcelain veneers must be bonded with a correct adhesive technique to reach this successful survival rate.
