Test of Relative Translucency for Four All-Ceramic Core Material after Veneering Ceramic
Objective:To study the relative translucency of 4 veneered and glazed all-ceramic systems core material,including Vita In-Ceram Alumina,Vita In-Ceram Zirconium,Ivoclar Vivodent Empress and Colored Zirconia.Methods:Under standard black and write background,the surface light reflectivity of 4 veneered all-ceramic systems core material was determined with contact color difference meter,and the ratio of Yb /Yw was calculated.Results:After veneered,the relative translucency of 4 core materials all declined,and ranged from 0.8015 of Colored Zirconia to 1.00 of In-Ceram zirconia,among of that Empress Ⅱ and Colored Zirconia were most transparent.Conclusion:Among the groups,there is no significant difference between Empress Ⅱ and Colored Zirconia (IL1,IL2,IL3).Compared with Vita In-Ceram Alumina and Vita In-Cerarn Zirconium,Vita In-Ceram Alumina (AL1) has significant difference.There is no significant difference between Vita In-Ceram Zirconium and Vita In-Ceram Alumina (AL2,AL3,AL4).
