牙科自修复微胶囊材料的研究进展

Research progress of dental self-healing microcapsule materials

自修复微胶囊材料是一种能够自我识别并修复微裂纹的智能材料,将其加入到牙科树脂材料中能够对抗微裂纹的产生,延长树脂的使用寿命。本文概述了自修复微胶囊材料,并从自修复微胶囊材料与其他改性材料的联合应用,自修复微胶囊的硅烷化处理,自修复牙科树脂的动态力学、疲劳及老化研究进行了简要综述,同时对牙科自修复微胶囊材料的发展方向进行了展望。

The self-healing microcapsule material is one of the smart materials that can self-identify and self-heal microcracks.Adding microcapsules to dental resin composites can resist generation of microcracks and prolong service life of resin restorations.In this literature,the overview of self-healing microcapsule materials,the combined application of self-healing microcapsule materials and other modified materials,the silanization treatment of dental self-healing microcapsules,the dynamic mechanics,fatigue and aging studies on self-healing dental resins were comprehensively presented and reviewed.In addition,prospects of dental self-healing microcapsule materials were also discussed.
