Introduction: The purpose of this study was to evaluate the fracture resistance of most used three preparation techniques applied laminate veneers made with three different restoration methods. Materials and Methods: 195 same sized maxillary central incisor teeth were grouped 10 different groups randomly. (testing groups n=20, control group n=15) Three different preparation techniques used for teeth preparation which were feather-edge, insical overlap and window. Laminate veneers were produced with three different methods that direct, indirect technique, and CAD/CAM milling. Control group was chosen from untreated teeth. Universal testing machinewas used for fracture resistance test. Data were analyzed with two-ways ANOVA and Tukey LSD. Results: According to results, statistically differences were found between all groups.(p<0,05) Combination of insical overlap preparation and direct technique has higher fracture resistance values than other groups.(563,9 N). Conclusions: Preparation and restoration techniques are important for fracture resistance of laminate veneers.
