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 .
