The composite resins have reached a high degree of excellence and are now utilized with predictable results in restoring the anterior dentition. This article discusses the development of these resins and the histologic and optical considerations (polychromatic characteristics, hue, translucency and opacity, chroma, value, strength, and polishability). In restorative materials, the use of universal or all-purpose restorative resins is considered, ie, materials that combine the functional strength necessary for the posterior regions and the high gloss polishability necessary to emulate enamel in the anterior. The restorative sequence of cervical, middle, and incisal thirds describes the materials best suited for each third, along with aids to create the intricate refinement of hue, chroma, and value. The learning objective of this article is to review the principles involved in these restorations and to provide a protocol for their clinical implementation.
复合树脂已达到很高的卓越程度,目前在修复前牙列方面应用效果可预测。本文讨论了这些树脂的发展以及组织学和光学方面的考虑因素(多色特性、色调、半透明度和不透明度、彩度、明度、强度和可抛光性)。在修复材料方面,考虑使用通用或多用途修复树脂,即结合后牙区域所需功能强度和在前牙模拟牙釉质所需高光泽可抛光性的材料。颈部、中部和切端三分之一的修复顺序描述了最适合每个三分之一的材料,以及用于精细调整色调、彩度和明度的辅助方法。本文的学习目标是回顾这些修复所涉及的原则,并提供其临床应用方案。
