The Transmittance Test of 3 All-ceramic System Core Materials

摘要：

　　This experiment was to study the transmittance of 3 all-ceramic system core materials,including 4 colors of Vita In-Ceram Alumina,4 colors of Vita In-Ceram Zirconium and 3 colors of Empress Ⅱ,and to provide basis for clinical choice of core materials.With Vita alpha veneer porcelain as control,the transmittance of all samples was determined with spectrophotometer under D65 standard source.The transmittance of materials was 1.434%~3.843% for Vita In-Ceram Alumina,0%~0.587% for Vita In-Ceram Zirconium,5.620%~6.665% for Empress Ⅱ.As a whole,the transmittance of Empress Ⅱ was the best of 3 core materials,that of In-Ceram Alumina was the worse,that of Vita In-Ceram Zirconium was the worst.
