摘要
传统复合树脂在临床应用中分层充填,步骤较多,树脂的聚合收缩可导致修复体边缘微渗漏、术后敏感等,导致修复失败。2009年,大块充填树脂(bulk-fill resin-based composite)应运而生,改良的基质单体、改性强化的纳米混合填料以及独特的光引发剂,使得大块充填树脂能够一层充填4 mm,其简化操作步骤、节约椅旁时间、并能显著降低聚合收缩和聚合应力。本文就大块充填树脂的分类、固化原理、性能等方面进行阐述和讨论,并提出大块充填树脂的应用发展方向。
Traditional resinbased composites have been placed in cavities by incremental layering technique.The shrinkage stress may result in microleakage,postoperative sensitivity which lead to the failed restorations.In2009,bulkfill resinbased composites were reported to have the capability to be placed and cured in4-5mm increments,because of the improved resin matrix,modified nanohybrid fillers and new photo initiators.This group of materials cansimplify operation in clinical application in addition to decrease shrinkage stress and polymerization shrinkage.The aim of this review is to summarize the classification and properties of bulkfill resin?based composites and to discuss the development of these new materials in the future.
