摘要

阴影选择是假肢治疗过程中至关重要的临床步骤。然而,由于它是基于主观标准,因此往往由于色彩再现不足而损害了审美结果。为了探究这一复杂的问题,本文试图对其进行尽可能科学的分析。首先,分析了“颜色”的物理现象。颜色取决于光源、物体和观察者。同分色是色差匹配的致命敌人。由于缺乏标准化,通过使用遮阳指南进行遮阳选择是不充分的。因此,在简单和更复杂的情况下,对现有材料的改进应用的可能性进行了彻底的探索。分段选色(牙本质和牙釉质分别选色)可获得最佳效果。

[Shade selection in fixed prosthodontics].

Shade selection is a crucial clinical step during prosthetic treatment. Nevertheless, because it is based on subjective criteria, very often the esthetic result is compromised due to inadequate color reproduction. In order to explore this complicated problem, this paper attempts to analyse it as scientifically as possible. Initially, the physical phenomenon of "Color" is analysed. Color depends upon the light source, the object and the observer. Metamerism is the fatal enemy in shade matching. Shade selection through the use of shade guides is inadequate due to lack of standardization. Therefore the possibilities of improved application of the available materials are thoroughly explored for both simple and more complicated cases. Best results can be achieved by segmental color selection (separately for dentin and enamel).
