Effect of thickness on optical properties of monolithic CAD-CAM ceramics

Conclusions Material type and thickness can be expected to affect color change and relative translucency of the restorations made with preshaded MonZr, LDS and ZLS materials. Except for 0.5 mm thick ZLS material, color changes of all studied materials were within the clinically acceptable limits. Except ZLS material, color changes of other materials were not significantly affected by thickness. Staining in coffee was not found to affect translucency, and the materials’ translucency parameters were ranked from high to low as LDS, ZLS and MonZr at each thickness studied.
