牙科复合材料的聚合伴随着显著的收缩和内应力的产生。这种应力被认为是复合材料中出现边缘差异的一个原因。本文提供了一个概述的起源，这些应力在聚合牙科复合材料，测量它们的方法的简要描述，什么是鲜为人知的收缩应力和结果之间的关系的讨论，识别的材料和放置因素，影响收缩应力，并提出了几种策略，以减少应力的描述。牙科复合材料中的收缩应力发展现象非常复杂，尽管进行了许多研究，但仍然是一个重要的临床问题。(C)2004年牙科材料学院。由爱思唯尔有限公司出版。保留所有权利。
The polymerization of dental composites is accompanied by significant shrinkage and the production of internal stress. This stress has been implicated as a causative factor for marginal discrepancies seen in composite restorations. This paper provides an overview of the origins of these stresses in polymerizing dental composites, a brief description of the methods for measuring them, a discussion of what little is known of the relationship between contraction stress and outcomes, an identification of the materials and placement factors that affect contraction stress, and a description of several strategies proposed to reduce the stresses. The phenomenon of contraction stress development in dental composite restoratives is highly complex, and despite many investigations, remains as a significant clinical concern.
