INTRODUCTION: In recent years, the increase in esthetic demands and the progress in adhesive systems have brought more attention to the treatment of the anterior region.In this context, direct composite veneers are widely preferred.The aim of the study is to compare the 18-month clinical performances of prefabricated composite veneers and direct composite veneers fabricated with transparent templates.MATERIAL and METHODS: This randomized, prospective in-vivo study included 21 volunteers and a total of 74 anterior veneers (36 laterals, 38 centrals).Prefabricated veneers were placed using the Edelweiss system; direct veneers were made with U-Veneer templates and Ceram-X Duo SphereTEC.All procedures followed manufacturers' instructions, and no additional mechanical polishing was performed.Clinical evaluations were conducted at baseline, 6, 12, and 18 months by two experienced, blinded examiners using modified Ryge (USPHS) criteria (color match, marginal discoloration/adaptation, anatomic form, secondary caries, retention loss, surface roughness, polish retention, postoperative sensitivity, and patient satisfaction).Statistical analyses used McNemar and Kolmogorov-Smirnov Z tests (p<0.05).RESULTS: After 18 months, both approaches were clinically successful with high patient satisfaction.No statistically significant differences were found between groups.Over time, a significant change was observed only in the polish retention criterion (p<0.05).CONCLUSION: Both techniques are reliable short-to-mid-term options for anterior esthetics.Considering long-term outcomes, fine finishing and polishing of veneer surfaces are recommended with attention to patients' dietary habits.
