This study aims to evaluate the effect of different ceramic materials and their thicknesses on the implant abutment backgrounds to the final color of restorations. The monolithic and porcelain-veneered zirconia experimental specimens made from three translucent zirconia (Prettau Anterior, Vita YZ ST and Vita YZ HT) were prepared in the disc-shaped A3 shade with two different thicknesses (1 and 1.5 mm) (n=10). Three abutment backgrounds were prepared from the titanium, whiteshaded and yellow-shaded zirconia. The zirconia specimens were placed on different backgrounds and colors (?E) between the experimental and the control specimens measured in the CIELab system. The results showed that the mean ?E values between the two thicknesses were significantly different in every background for all zirconia materials. The ?E values of the zirconia specimens on the yellow zirconia were lower than other abutments in all thicknesses. The mean ?E within the clinically acceptable values (?E<3) was found in some monolithic zirconia specimens on the white-shaded and yellow-shaded abutment while the ?E values were approximately 3 or less in all 1.5-mm-thick porcelain-veneered zirconia groups.
