摘　　要：目的探索陶瓷材料颜色匹配中色调变化及明度变化的规律。方法制作镍铬合金片15片,于其上烧结不同色号的VINTAGE系列套装瓷粉,样本组的瓷样本依次由A1和A2、A2和A3、A3和A4、B1和B2、B2和B3、B3和B4色号的瓷粉按体积比等量混色后烧结而成;对照组瓷样本则依次由A1、A2、A3、A3.5、A4、B1、B2、B3、B4色号的瓷粉烧结而成。在PR650分光光度仪上对瓷样本行色度学测试,利用Photo Research颜色分析软件进行色度学参数分析。结果相同色系不同色号瓷样本的L*a*b*值有统计学差异(P<0.05),不同色号陶瓷材料等量混色后其色度学参数a*、b*值的变化是一种非线性关系,这种颜色的改变可为人眼辨别。结论VINTAGE系列套装瓷粉中A色系的明度变化梯度大于B色系;相同色系不同色号等量混色时,2号色和3号色的明度梯度最大;A色系红-绿变化明显,B色系黄蓝-变化明显。Objective To study the color changes on brightness and hue in dental ceramic prothesis materials. Methods The different color mark of VINTAGE series was sintered on 15 pieces Ni-Cr alloy denture materials. The sample group and control group was given the sintering of color blending with equivalent volume. The order of color mark was of A1 and A2, A2 and A3, A3 and A4, B1 and B2, B2 and B3, B3 and B4 in sample group, and A1, A2, A3, A3.5, A4, B1, B2, B3 and B4 orderly in control group. The chromatic analysis on samples of VITA had been taken through applying PR 650 spectrum detector and adopted the statistic software of Photo Research and SPSS 12.0 for analysis. Results The statistical difference（P〈0.05） of L＊a＊b＊ value was found in the different color mark of the same color serials. A non-linearity relation had been found in the chromatic parameters a＊b＊. It means the change of color was visible. Conclusion Set A has a bigger grading change of brightness than Set B. The change of red-green is obviously in Set A, as well as yellow-blue in Set B.
