A Translucency for the Zirconia Laminate Veneers

Within the limitation of this study, the study concluded that :1- Different zirconia ceramic materials has variable degree of translucency and differ between each other .2- Translucency of lithium disilicate material is still the highest among other veneering materials .3- Thickness of the material has significant effect on TP values .4- Translucency of E-max and ZP at 0.5 mm thickness and WP and ZP zirconia materials at 0.3mm thickness was affected by artificial aging , also thinner samples are affected more by the artificial aging .5- Light cured luting cement showed higher degree of color change (dE) than dual cured luting cements .6- Artificial aging has no significant clinical change in the color of the samples cemented with both light and dual cure luting cement .
