摘 要: 口腔复合树脂的老化可产生微裂纹并逐步扩展使修复体完全破裂,是影响其在口内长期使用的重要因素.为早期修补微裂纹、提高复合树脂的长期耐久性,近年,学者将基于微胶囊模型的自修复体系引入口腔复合树脂,以提高其综合性能和临床使用寿命.现综述自修复材料的概念及分类,以及现阶段其应用于口腔复合树脂的研究进展,探讨口腔自修复复合树脂的发展方向. Degradation of composite resin during ageing always produces micro-cracks, the latter could gradually expand, leading to the fracture of tooth restoration. In order to extend the service life of composite resin by repairing cracks intelligently, self-healing microcapsule models have been introduced in resin-based dental materials. This paper will present the concept and classification of self-healing materials, and review the research progresses on self-healing dental resin.
