苏州地区人群钛瓷冠修复比色结果分析

The Analysis of Color Matching About the Ceramics Veneered Titanium Crowns in Suzhou Crowds

目的探讨钛瓷修复选色的特点和规律，为今后钛瓷修复的颜色重建提供参考。方法为口腔修复门诊病人224人制作钛金属烤瓷全冠，用Vita比色板按照明度、色调、饱和度的顺序在自然光线下为病人选色，由技师按照比色结果、参考比色板的颜色配色。结果选择A色系的人数最多，占总体色的51.8％，B、C色系次之，选择D色系的最少，而在A色系中，则以选择A2、A3色的最多，占总人数的44．6％。16种色标按比色频率多少排列顺序是：A3、A2、B3、D3、A3.5、B2、C1、C2、D2、C4、A1、B1、B4、C3、A4、D4，前4种颜色占总数的60．6％。结论苏州地区人群牙颜色主体在代表红棕色调的A色系，而且分布在饱和度较小、明度较高的区域；由于Vita比色板颜色分布不均匀而且人牙不是单一颜色，因此很难用单一色标再现天然牙色，应用多个色标的复合色复制天然牙色。
