The process of matching fixed prosthetic restorations to bleached dentition has often created a dilemma, as clinicians are not able to accurately communicate shade selection to the dental laboratory. By understanding the effect of vital bleaching on the dentition, it is possible to fabricate porcelain restorations that match the bleached natural teeth. This article presents a laboratory technique for utilizing a sequence of porcelain powders and stains to develop the internal anatomy (e.g., halos, mamelons, luminosity) of restorations that appear indistinguishable from the bleached dentition.
将固定义齿修复体与漂白后的牙列相匹配的过程常常会造成两难局面，因为临床医生无法准确地向牙科实验室传达颜色选择。通过了解活髓漂白对牙列的影响，就有可能制作出与漂白后的天然牙相匹配的瓷修复体。本文介绍了一种实验室技术，即利用一系列瓷粉和染色剂来塑造修复体的内部结构（如晕圈、切嵴结节、明度），使其与漂白后的牙列难以区分。
