![]() ![]() Besides, natural teeth and ceramics have different light absorption and reflection properties. The color and elements of color such as brightness of color, the intensity of color, translucency, opacity, color, light transmission, reflection, metamerism, and fluorescence affect the esthetic properties of a restoration. However, there are still problems waiting to be solved, which represent the dental porcelains' optical properties including the color of natural teeth. Much effort is made to produce restorations similar to natural teeth and other biological features, due to the increased esthetic needs. The hypothesis was accepted as a result of the study. The effect of different production techniques on color and translucency in full ceramics with zirconia substructure has been investigated in this study. There is a statistical difference between ΔE values according to construction techniques ( P 0.05). The results of one-way ANOVA are shown in. Table 2: Descriptive statistical values and multiple comparisons between groups While the lowest b* value was seen in the P group, the highest b* value was seen in the L group. ![]() The group with the highest a* value mean was found to be the T group. The results were analyzed with one-way ANOVA ( P 0.05). Color parameters (L* a* b*) were measured with a spectrophotometer and color difference (ΔE), and translucency parameter (TP) properties were calculated. ![]() Group CO the veneering ceramics were designed with and milled from lithium disilicate glass-ceramic blocks in CAD/computed aided manufacturing unit. Group P was heat pressed with fluorapatite glass-ceramic ingots. ![]() Group L was veneered with nano-fluorapatite veneering ceramic. Materials and Methods: Specimens were randomly divided into three groups ( n = 12): layering (L), pressing (P), and computed aided design (CAD)-on (CO). Aim: The aim of this in vitro study was to investigate the effect of different veneering techniques on the color, translucency, of zirconia-based systems. ![]()
