Abstract
Introduction: Monolithic Zirconia materials are a great innovation in esthetic and restorative dentistry, where nowadays they are accepted as a veneer material where it can affect depth of the preparation, translucency, and shade of the final veneer. Objectives: to investigate the effect of different thicknesses of Ultra and Super high Translucent Monolithic Zirconia on the translucency and the change in the final color from the selected Vita Classical shade. Materials and Methods: This in vitro study consisted of three groups(n=48); Three groups were tested according to different thicknesses of the material to be used: (Group I) (UTML) Katana (preshaded). (Group II) (STML) DD cubeX2 ML 98 (preshaded). (Group III) (ST) DD cubeX2 98(white). Each group was divided into two subgroups at different thicknesses of 0.5 mm and 0.7 mm. Each subgroup consisted of eight specimens of zirconia that were cut in the form of a disk. The shade was determined digitally using Easy shade V spectrophotometer. Results: The color was affected by the type of the Monolithic Zirconia while the translucency was significantly affected by the thickness and the type of Monolithic Zirconia. There was a significant increase in the Transparency Parameter of the Monolithic Zirconia specimens as we decrease the thickness of the specimen (p value < 0.05). Conclusion: Within the limitations of this study, Ultra Translucent Multilayered was shown to have the highest transparency parameter among the different thicknesses where the 0.7 mm was the minimum thickness required for monolithic zirconia to achieve the corresponding Vita classical shade.
