Abstract

Purpose: This study focused on achieving desired shades by combining zirconia core with different thickness porcelain in order to make dental prostheses effectively. Methods: White and colored $LAVA^{TM}$ All Ceramic (3M-ESPE, Seefeld, Germany), and Zirkonzahn (Bruneck, Italy) Trans and prettau were used to have Zirconia. LAVATM Ceram (3M-ESPE, Germany) and ICE (Zirkonzahn, Italy) powder were used to have the porcelain. We made quadrilateral specimen of thickness 0.3mm, 0.5mm, 0.7mm and diameter 10 to use zirconia ceramics system of 2 kinds that color tone reappearance way is different and produced total 120 specimens to 4 experimental groups. We used Spectrophotometer to analyze color tone. Data's value getting by dispersal colorimetry period found L*, a*, b* value using Excel program. We used one-way ANOVA to use SPSS WIN 12.0 program. Results: All L*, a*, b* indexes of zirconia core and porcelain veneer in LAVA group and Zirkonzahn group were different. When you combine the white zirconia core of LAVA group with a porcelain veneer, the thickness of the porcelain must be more than 0.5mm to meet the standard target. When all the colored zirconia cores of LAVA group were combined with porcelain veneers, there was no significant difference from the standard target. When the zirconia cores of Zirkonzahn group are combined with porcelain veneers, the thinner thicknesses were closer to the standard tab than thicker thicknesses; however, there was a significant difference in all combinations, with Delta E* value indicating more than 3. Conclusion: When it comes to colored zirconia, which is the most popular, the thicknesses of both a core and a dentin veneer must be more than 0.3mm to get an appropriate shade. There is more possibility to get desirable shades when the thicknesses of a white core are thinner; however, they would be vulnerable to the environment and lose their color. When combine a zirconia core with a dentin veneer, using Zirkonzahn group needs more considerations in order to meet the standard target.
