title: The clinical longevity of porcelain veneers: a 48-month clinical evaluation.
abstract: The authors evaluated the clinical longevity of a brand of porcelain veneers and the accompanying cementation system. Fifty-nine porcelain veneers were prepared and placed in 12 patients by one practitioner and evaluated by two evaluators using modified Ryge criteria at baseline and 12 months. Fifty-three veneers were evaluated similarly at 48 months. Plaque index and gingival index scores were recorded as well. At 48 months, the veneers had stable color, all margins were clinically acceptable, there was no secondary caries and the patients reported no sensitivity.
