Existing dental shade guides are not arranged logically or scientifically and do not even correspond to measured tooth colour. Shade guides of all dental restorative materials are based on the long established porcelain shade guides which evolved to represent the available shades of porcelain teeth. The shades developed by a process of popular selection by which shades perceived to be nearer tooth colour were added and the least popular eliminated. This concept has not changed since the introduction of porcelain over two hundred years ago. The approach presented is fundamentally different with the colours evolved from measured tooth colour. By applying colour science a system for colour selection is developed specifically for tooth colour. Existing methods and problems are evaluated and the difficulties of colour matching quantified. A tooth colour order system is developed resulting in the construction of a tooth colour atlas assembled for easy use offering the accurate measurement of tooth colour and the potential of perfect colour matching.
现有的牙齿比色板在逻辑和科学性上都存在不足，甚至与测量得到的牙齿颜色不相符。所有牙科修复材料的比色板都是基于长期以来已确立的烤瓷比色板，这些比色板逐渐发展以呈现烤瓷牙的可用颜色。这些颜色是通过大众选择的过程确定的，即添加那些被认为更接近牙齿颜色的色调，并淘汰最不受欢迎的色调。自两百多年前引入烤瓷以来，这一概念从未改变。本文提出的方法则截然不同，其颜色源自测量得到的牙齿颜色。通过应用色彩科学，专门为牙齿颜色开发了一种颜色选择系统。对现有方法和问题进行了评估，并对颜色匹配的难度进行了量化。开发了一种牙齿颜色排序系统，进而构建了一本便于使用的牙齿颜色图谱，它能够提供准确的牙齿颜色测量以及实现完美颜色匹配的可能性。
