    摘 要 目的：为提高钛义齿的美学效果，评价钛义齿阳极氧化着色 的均匀性。方法：制作5副阳极氧化着色上颌钛腭托，用CR-321型色彩色差计在每副义齿腭 侧5个部位测量其表色值，用标准色差公式计算其色差。通过CIE1976L^*a^*b^*均匀颜色 空间定量评价各测量点色彩的一致性。结果：钛义齿各测量点的色差△Eab均小于1. 3，人眼不能分辨。结论：阳极氧化法可使钛义齿表面呈均匀的金黄色，能增进义齿支架的 美学效果。

    Abstract Objective：To investigate the chromatic uniformity of anodized titanium denture frameworks. Methods：Five anodize d upper titanium denture bases were fabricated for chromatic measurement. The co lor specification values L^*a^*b^* were measured on five positions of each de nture base surfaces using a chromameter.Then the magmitude of the total color di fference between the measured positions was formulated by a single number of △E through in term of the values of L^*a^*b^*,and evaluated in the CIELab unifo rm color scale.Resukt：The values of total color differences between the m easured positions were less than 1.3,which is not differentiated by the naked e yes.Conclusion:The golden color on the surface anodized titanium denture framew orks is uniform, improving the aesthetic appearance of titanium dentures. ......
