Porcelain laminate veneers are widely accepted as the treatment of choice to noninvasively restore the esthetics and function of anterior teeth, provided there is a sufficient amount of tooth structure to support the reconstruction. However, there are certain esthetic limitations if the underlying tooth structure is discolored, which may occur in cases of nonvital roots. This article describes how to manage this esthetic challenge. Internal bleaching, tooth-colored internal buildups, and preparation guidelines are discussed via clinical case presentations.
瓷贴面作为一种无创修复前牙美观和功能的治疗选择已被广泛接受，前提是有足够的牙体组织来支持修复。然而，如果基牙牙体组织变色，就会存在一定的美观限制，这种情况可能发生在死髓牙根的病例中。本文介绍了如何应对这一美观挑战。通过临床病例展示讨论了内漂白、牙齿颜色的内部堆积和预备指南。
