The acceptance of mercury-containing restorative materials has declined, and the demand for amalgam substitutes has resulted in development of a variety of composite resins. Microhybrids are the newest generation of composite resins, and they incorporate particles of different sizes to maximize wear, polishability, and handling characteristics. The learning objective of this article is to present a technique to maximize form, function, and aesthetics in the placement of a posterior composite resin restoration. Shade selection, use of caries indicator, "total etch" technique, new generation bonding agent, and incremental resin placement are discussed. A step-by-step case presentation demonstrates that an appropriately placed direct posterior composite resin provides an excellent alternative to the traditional metal-colored restorations.
含汞修复材料的接受度已下降，对汞合金替代品的需求促使了多种复合树脂的研发。微混合树脂是最新一代的复合树脂，它们包含不同尺寸的颗粒，以最大限度地提高耐磨性、可抛光性和操作特性。本文的学习目标是介绍一种在后牙复合树脂修复体放置中最大化形态、功能和美观性的技术。文中讨论了比色、龋病指示剂的使用、“全酸蚀”技术、新一代粘结剂以及分层放置树脂。一个逐步的病例展示表明，放置得当的直接后牙复合树脂修复体是传统金属色修复体的极佳替代品。
