Abstract: The aim of the study is to evaluate the effect of different surface treatments on the micro-Tensile Bond Strength (μTBS) of hybrid composite to to Lava Ultimate and Vita Ena-mic resin-nanoceramic CAD/CAM blocks/in this study for each CAD/CAM block 4 samples were prepared and divided according to surface treatment to 4 groups as follows: control, 50 μm (Al2O3) airborne-particle, femtosecond laser and combina-tion of 50 μm (Al2O3) airborne-particle and femtosecond laser. One additional sample for each CAD/CAM block were prepared for each surface treatment group for SEM analysis. Filtek Z250 hybrid composite was adhered onto each sub group after application of universal single bond adhesive. Mikro Tensile Bond Strength (μTBS) test for each sample was eveluated after 1000 thermal aging cycle. Bond strengths were analyzed through two-way ANOVA test. Tukey LSD test was used for multiple comparisons of the groups. For all groups, the control group showed the lowest bond strength values and the difference was statistically different (p<0.05). Combination of sandblasting and laser groups showed highest bond strength values (p<0.05). There is no statistical difference between sandblasting and laser surface treatment (p>0.05). The SEM images were supported the (μTBS) data. As a result of this study using these methods of surface treatments is expected to increase clinical success of there storations.
