摘要： The present invention relates to a method for preparing the color of a dental restoration using a spectrophotometer and a unique color system for porcelain dental restorations which enables a dentist or technician to manipulate the various color components of the porcelain, hue, chroma, value, and translucency, independently. Color component deltas between consecutive colors in the powder sets are equidistant, with the difference in values being linear in color space. This enables simplified, exact matching of a specified color component value. The method comprises illuminating an abutting tooth with light, gathering reflected light, converting the gathered light to analog signals, correct for ambient light interference, translucency effects (if necessary) and varying illumination, using the result to obtain accurate color component values, and employing those values to chose and, where necessary, mix the appropriate powers to obtain the correct color porcelain for the desired dental restoration.
摘要翻译：本发明涉及一种使用分光光度计和用于瓷牙修复体的独特颜色系统来制备牙科修复体的颜色的方法，其使得牙医或技术人员能够操纵瓷器，色调，色度，价值和半透明，独立。粉末组中连续颜色之间的颜色分量增量是等距的，其中值的差异在颜色空间中是线性的。这使得能够简化，精确匹配指定的颜色分量值。该方法包括用光照射邻接齿，收集反射光，将收集的光转换成模拟信号，校正环境光干扰，半透明效应（如果需要）和变化的照明，使用结果获得准确的色分量值，并采用选择这些价值观，并在必要时混合适当的力量，以获得所需牙科修复体的正确色瓷。
