Introduction: Previous literature has revealed a significant effect of various trial insertion pastes materials on the translucency of ceramic veneers. However, the evidence regarding the impact of cement thickness on the final shade of the glass-ceramic, feldspathic, and zirconia reinforced glass-ceramic veneers is inconclusive. Objective: The aim of the present study was to evaluate the translucency of three different CAD/CAM processed veneer materials with different internal relief spaces and cement shades. Methodology: Sixty acrylic samples were prepared and classified according to the type of materials into three main groups: IPS e.max CAD MT, VITA Vitablocs Mark II, and Vita Suprinity, comprising 20 samples each. Based on the internal relief spaces (100 µm and 30 µm), each group was subdivided into two subgroups (10 samples each). Each subgroup was further subdivided into six classes according to the type (10 samples each) and the shade of the trial cement used. Glycerin was used as the control class, and five different trial pastes (translucent, white opaque, A1/Light Yellow, A3 opaque/yellow opaque, and B0.5/ white shades) were used according to their shade. The color test was conducted using a reflectance spectrophotometer device (Vita Easy shade V). Color coordinates were measured in the body region of all laminate veneers with different combinations of laminate veneer material, internal relief space, and trial insertion paste color on composite resin abutment A3. The consistency of the translucency among the tested specimens was confirmed using a two-way ANOVA and the Tukey HSD post hoc test (P< 0.05). Results: The luminous transmittance exhibited a statistically significant dependence on different ceramic restorations in CAD/CAM veneers with various internal relief spaces and different combinations of cement shades (P< 0.05). Conclusions: The underlying color of the tested trial insertion pastes caused color change (∆E>3.7) for all ceramic material used.
