摘　　要：可注射型组织工程骨支架材料是一种具有一定形态和机械强度的支架材料,可与种子细胞复合,以流体的形式注射到骨组织缺损部位,最终形成新骨,达到结构恢复和功能重建的目的.此材料具有创伤小、可塑性好的特点,可以修复形态不规则的骨缺损,能够很好地复合生长因子,是目前较为理想的骨组织缺损的修复方式.在众多可注射骨组织工程材料中,生物陶瓷材料、高分子材料等被证明有高度的生物相容性和良好的机械性能,已成为骨组织工程材料方面的研究重点.旨在对生物陶瓷材料、高分子材料、生物陶瓷与高分子复合材料的发展与应用作一综述.Injectable bone tissue engineering scaffold material has a certain form and mechanical strength.It can be loaded with seed cells for injection to the defected site of bone tissue in the form of fluid.After that,structural recovery and functional reconstruction are achieved,and the new bone is formed ultimately.This material has the characteristics of small trauma and good plasticity.It can repair the irregular bone defects and well associate with growth factor,which is the ideal method for repairing bone tissue defects up to now.Among the various injectable bone tissue engineering materials,bioceramic materials,polymer materials,etc.have been proved to have a high biological compatibility and good mechanical properties.That makes these materials become the focus of current research in bone tissue engineering materials.In this paper,the development and application of bioceramic materials,polymer materials,bioceramics and polymer composites were reviewed.
