摘要: 生物源性磷酸钙类骨替代材料具有良好的生物相容性及骨引导性能,广泛应用于口腔种植临床的骨缺损修复治疗。通过植入微量元素并控制其释出量,以调控骨微环境及促进成骨,已成为一种重要的骨再生材料优化策略。近年来,系列研究显示氟化猪源性骨替代材料具有良好的理化性能及氟离子缓释特性,可通过激活骨髓间充质干细胞中Wnt/β-catenin信号通路及调节局部免疫微环境诱导骨形成,并在多种骨缺损动物模型中表现出良好的骨再生效果。本文对氟化猪源性骨替代材料的研究进展进行总结,以期为相关基础研究及临床应用提供参考。

Abstract: Biological calcium phosphate-based bone substitutes have been widely used in the rehabilitation of bone defects in implant dentistry, due to their great biocompatibility and osteoconductivity. It has become an important optimizing strategy for bone regeneration materials through trace elements incorporation and controlled release to promote osteogenesis by regulating the regenerative microenvironment. In recent years, a series of studies have shown that fluorinated porcine bone substitute has good mechanical properties and the capacity of fluorine slow-release which could promote bone regeneration by activating the Wnt/β-catenin signaling pathway and regulating the immune microenvironment. Such an in vitro effect of fluorinated porcine bone substitute has been evidently proven in a variety of subsequent studies in vivo. This article summarized the research progress of the fluorinated porcine bone substitute so as to provide a reference for related basic research and clinical application.
