Abstract

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.

摘要

复合树脂在老化过程中的降解总会产生微裂纹，微裂纹会逐渐扩展，导致牙齿修复体断裂。为了通过智能修复裂纹来延长复合树脂的使用寿命，基于树脂的牙科材料中引入了自修复微胶囊模型。本文将介绍自修复材料的概念和分类，并综述自修复牙科树脂的研究进展。
