摘要
目的:研究Vita In-Ceram渗透陶瓷技工比色板颜色分布的规律性。方法:采用Minolta CM-2600d分光测色计、国际照明委员会(CIE)推荐的CIE-1976-Lab色度系统对Vita In-Ceram渗透陶瓷技工比色板进行颜色测定和分析。结果:Vita In-Ceram 渗透陶瓷技工比色板分别对应玻璃渗透尖晶石、氧化铝和氧化锆陶瓷三种材料系列,各有4个比色片,总体明度范围为81.40~67.68,按比色片序号增大而明度递减,饱和度递增,色相角递减,其中渗透铝瓷组的AL3饱和度为该组中饱和度最大。结论:In-Ceram渗透陶瓷技工比色板三种材料系列的颜色分布有共同的规律性,渗透陶瓷的颜色作为Vita alpha饰面瓷的背景色,可以使最终修复体颜色与Vita 临床比色板的颜色具有良好的匹配性。
Objective: To reveal the logical color range in Vita In-Ceram technical shade guide. Methods: The color range and ordering of Vita In-Ceram technical shade guide was measured and analyzed with MINOLTA CM-2600d spectraphotometer under D65 standard source, CIE-1976-Lab system was adopted. Results: There were three types of materials corresponding to Vita In-Ceram technical shade guide,each type have 4 shade tabs. The overall L value range of this shade guide was 81.40~67.68. With the increased number of the shade tabs, the L value decreased, Chroma increased and hue decreased. While the shade tab AL3 was the most saturated shade tab in infiltration alumina group. Conclusions: There is common logical ordering in three types of materials in In-Ceram technical shade guide.As a background of the Vita alpha veneering porcelain, this logical color ordering makes it possible that color match could be reached with Vita clinical shade guide.
