Introduction: Ceramic veneers are increasing worldwide. Objective: Evaluate the effect of surface loss on color stability and strength of ceramic veneers. Methods: 40 incisors were divided into 4 groups; A: the incisal third was removed, B: one third was removed, C: one half was removed D: intact tooth. Teeth of (A, B and C) were restored with composite. Teeth received ceramic veneers. Fracture resistance and color were evaluated. Results: Fracture resistance showed no significant difference between the 4 groups, while one half surface loss affected the color stability. Conclusion: The results suggested full ceramic coverage when loss is one half.
