The no prep technique to ceramic veneer have some advantages, one of the most important is the preservation of tooth structure. Purpose: Evaluate fracture resistance in bovine teeth, of ceramic veneer in different thickness (0,3 to 1,0mm). Methods: 60 teeth were selected for this study. Forty fifth ceramic veneer were made for each tooth, variating the thickness in: G1 – 0,7mm; G2 – 0,5mm; G3 – 0,3mm and G4 – 1,0mm (control group). Flexural strength test was carried out after 24h of luting. The results were analysed by ANOVA and HSD of Tukey. Results: the results showed that was no statistic difference between the groups (G1297.2200; G2 294.5467; G3 291.9380 and G4 -290.0733). Conclusion: The ceramic veneer thickness didn’t have influence in the final flexural strength.
