Test of Relative Translucency for Three Veneered All-ceramic Systems Core Material
Objective: To study the relative translucency of 3 veneered and glazed all-ceramic systems core material. including Vita In-Ceram Alumina,Vita In-Ceram Zirconium and Ivoclar Vivodent Empress. Methods: Under standard black and write background,the surface light reflectivity of 3 veneered all-ceramic systems core material was determined with contact color difference meter,and the ratio of Yb fYw was calculated. Results: After veneered,the relative translucency of 3 core materials all declined,and ranged from 0.8880 of Empress II to 1.00 of In-Ceram zirconia,among of that Empress II was most transparent. Conclusion: The relative translucency of 3 veneered all-ceramic systems core material had significant statistical difference. There was a decreasing range as Vitadur Alpha dentin (standard) > Empress 11 (0.8 mm) > InCeram Alumina > In-Ceram Zirconia.
