Clinical evaluation and comparison of porcelain laminate veneers and computer aided design and computer aided manufacture veneers / 中华口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the clinical application of a computer aided design and computer aided manufacture (CAD/CAM) veneer system.</p><p><b>METHODS</b>Sixty-five CAD/CAM veneers were made for 23 patients and 105 porcelain veneers were made for 25 patients. After three years, the clinical performance of two veneer systems were evaluated and compared according to modified California Dental Association/Ryge criteria. The clinical success rate and patient satisfactory rate were calculated.</p><p><b>RESULTS</b>The success rates of porcelain veneer and CAD/CAM veneer were 96.2% and 93.8%, respectively. The patient satisfactory rates were 92.4% and 90.8%. There was no significant difference between two veneer systems in color match, marginal discoloration and marginal fit. But the surface texture of CAD/CAM veneers was better than that of porcelain veneers.</p><p><b>CONCLUSIONS</b>CAD/CAM veneer system was a successful approach for veneer restorations.</p>
