Composite dental restorative materials have advanced considerably over the past 10 years. Although composites have not totally replaced amalgam, they have become a viable substitute in many situations. Problems still exist with polymerization contraction stress, large differences in the coefficient of thermal expansion (CTE) of composites compared with tooth structure, and with some technique sensitivity; however, new expanding resins, nanofiller technology, and improved bonding systems have the potential to reduce these problems. With increased patient demands for esthetic restorations, the use of direct filling composite materials will continue to grow. The one major caveat to this prediction is that clinicians must continue to use sound judgment on when, where, and how to use composite restoratives in their practices.
在过去十年中，复合牙科修复材料取得了长足的进步。尽管复合材料尚未完全取代汞合金，但在许多情况下，它们已成为一种可行的替代品。聚合收缩应力、复合材料与牙齿结构的热膨胀系数（CTE）差异较大以及一些技术敏感性方面仍然存在问题；然而，新型膨胀树脂、纳米填料技术和改进的粘结系统有可能减少这些问题。随着患者对美观修复的需求增加，直接填充复合材料的使用将继续增长。这一预测的一个主要警告是，临床医生在实践中必须继续对何时、何地以及如何使用复合修复材料做出明智的判断。
