可降解形状记忆聚合物在口腔医学领域应用研究进展

形状记忆聚合物在适当的刺激(温度、光、电、磁、溶剂)下,可以完成从暂时态到永久或者初始形状的转变。其中,热致型形状记忆聚合物最具代表性,可以通过转变温度来完成形状记忆。在医疗领域,生物相容性、机械性能、可降解性等都是至关重要的因素。凭借形状记忆效应,可降解形状记忆聚合物在生物医学领域具有广阔的应用前景。本文就形状记忆聚合物的记忆机理、可降解形状记忆聚合物的分类及其在口腔医学领域的应用作一综述。

Research Progress on the Oral Medical Applications of Biodegradable Shape Memory Polymers.

Shape memory polymers have the ability to switch from a temporary status to permanent status or transfer original shape triggered by heating, light irradiation, electrical stimulation, magnetic exposure or immersion in water. Among them, the heat-induced shape memory polymer is the most typical representative, which can change through a transition temperature. On the medical area, the relevant considerations, such as biocompatibility, mechanical property and biodegradability, are important factors. Depending on shape memory effect, biodegradable shape memory polymers have emerged as an extensive and potential alternative to other materials. In this article, the shape memory principle of shape memory polymers is discussed. The classification and oral medical applications of biodegradable shape memory polymers are introduced.
