载入高分子有机相增强磷酸钙骨水泥力学性能的方法

      Mechanical Reinforcement Strategy of Calcium Phosphate Cements by Loading Polymers

      • 摘要: 磷酸钙骨水泥(CPC)具有良好的生物活性,但CPC是脆性材料,抗压强度和弯曲强度低,目前只应用在非承重部位的骨缺损修复。该文综述了近年来载入各类高分子有机相来增强CPC力学性能的研究,归纳总结了载入纤维、高分子微球,制备双相固化CPC这几种增强力学性能的方法。分析总结这些增强方式的优缺点及其原理,为进一步改进、制备力学性能优异、符合承重部位的骨缺损修复要求的CPC奠定基础。

         

        Abstract: Calcium phosphate cement (CPC) is well known for the excellent bioactivity and biocompatibility, however, CPC has been used only for the repair of non-load bearing bone defects due to its brittle nature and low flexural strength. Polymer reinforced CPC has been considered as one of the most effective strategies for mechanical reinforcement. This paper summarizes various kinds of polymers loaded CPC:fiber reinforcement, microsphere reinforcement and dual setting cements. It is aimed to analyze the advantages, disadvantages and principles of the polymers reinforced CPC, and so as to lay a foundation for the further research of improving and manufacturing the CPC with ideal mechanical properties.
