A comprehensive knowledge of the optical properties of composite resins is essential to achieving optimal results in direct anterior restorations. This case report describes an anterior composite resin restoration fabricated with a layering technique and explains how to use a simple photographic method to verify that the desired optical effects are reproduced. A Class IV restoration was completed on a maxillary central incisor with the help of a silicone guide. An esthetic result was achieved through careful color examination as well as material selections that were based on knowledge of the translucency, opacity, and fluorescence of the chosen direct composite resins. The approach of combining a composite resin designed for bleached teeth with highly opalescent and translucent resins as well as matching the natural dental anatomy provided excellent esthetic results. The suitable reproduction of optical characteristics was confirmed by increasing the contrast of the final photograph, which highlighted the translucency achieved in the area of the mamelons.
全面了解复合树脂的光学特性对于在前牙直接修复中获得最佳效果至关重要。本病例报告描述了采用分层技术制作的前牙复合树脂修复体，并解释了如何使用一种简单的摄影方法来验证是否再现了所需的光学效果。在硅树脂导板的帮助下，对上颌中切牙完成了IV类修复。通过仔细的颜色检查以及基于所选直接复合树脂的半透明度、不透明度和荧光知识进行的材料选择，实现了美观的效果。将专为漂白牙齿设计的复合树脂与高乳光和半透明树脂相结合的方法，以及与天然牙齿解剖结构相匹配，提供了出色的美观效果。通过增加最终照片的对比度来确认光学特性的适当再现，这突出了切牙乳头区域实现的半透明度。
