牙齿美学修复比色

Shade selection in esthetic restoration

口腔临床比色是牙齿美学修复过程中的关键步骤之一。口腔临床比色分为视觉比色和仪器比色。视觉比色是临床比色最常用的方法,比色时应对天然牙的光学特征进行全面分析,注意比色过程中光照、背景等每一个细节,同时应拍摄高精度数码照片传递比色信息。仪器比色为视觉比色的有益补充和客观参考,作为修复专科医生,要多掌握比色相关的知识,并加强训练,才能不断提高比色的准确性。

Clinical shade selection is one of the key steps in esthetic restoration. There are two kinds of shade selection,namely visual shade selection and instrument-based shade selection. Optical properties of the natural teeth should be analysed carefully;visual shade selection should be completed under proper conditions such as lighting and background. High resolution digital photos are necessary to communicate color information with technicians. Instrument based shade selection is more objective and can be an adjunct to visual shade selection. Prosthodontists should be trained to master shade selection technique.
