摘　　要：目的:Cercon base氧化锆、Cercon base color氧化锆、Vita In-Ceram Z21色瓷沉积氧化锆、AL2色瓷沉积氧化铝陶瓷材料相对透明率的对比测定。方法:应用分光测色计在标准黑白背景下分别测量4组全瓷底层材料的表面光反射率,计算得出相对透明率数值。结果:Cercon base氧化锆的相对透明率为0.950,Cercon base color氧化锆0.937,Vita In-Ceram Z21色瓷沉积氧化锆1.000,Vita In-Cer am AL2色瓷沉积氧化铝0.869。结论:4种全瓷系统底层材料中Vita In-Ceram Z21色瓷沉积氧化锆和AL2色瓷沉积氧化铝的相对透明率差异有统计学意义(P<0.01),且In-Ceram AL2色瓷沉积氧化铝较In-Ceram Z21色瓷沉积氧化锆透明,其余组间的相对透明率差异均无统计学意义(P>0.01)。Objective To investigate the relative translucency of Cercon and In-Ceram ceramics system core materials, including Vita In-Ceram Electroformed Alumina crown （AL2）, Electroformed Zirconia crown （Z21）, Cercon base color Zir- conia and Cercon base Zirconia. Methods： The reflectivity of all samples was determined with chromatism instrument , and the ratio Yb/Yw was calculated. Results： The relative translucency of Cercon base Zirconia was 0.950, Cercon base color Zirconia 0.937, Vita In-Ceram Electroformed Zirconia crown （Z21） 1.000, Vita In-Ceram Electroformed Alumina crown （AL2） 0.869. Conclusion： The differences of relative transparency between 4 kinds of all ceramic substrate materials are not statistically significant （P〉0.01） except that between Vita In-Ceram Electroformed Zirconia crown （Z21） and Electro-formed Alumina crown （AL2） （P〈0.01）. And Vita In-Ceram Electroformed Alumina crown（AL2） is more translucent than Vita In-Ceram Electroformed Zirconia crown （Z21）.
