Bioactive glass (BG) has been widely used in the preparation of artificial bone scaffolds due to its excellent biological properties and non-cytotoxicity, which can promote bone and soft tissue regeneration. However, due to the brittleness, poor mechanical strength, easy agglomeration and uncontrollable structure of glass material, its application in various fields is limited. In this regard, most current researches mainly focus on mixing BG with organic or inorganic materials by freeze-drying method, sol-gel method, ., to improve its mechanical properties and brittleness, so as to increase its clinical application and expand its application field. This review introduces the combination of BG with natural organic materials, metallic materials and non-metallic materials, and demonstrates the latest technology and future prospects of BG composite materials through the development of scaffolds, injectable fillers, membranes, hydrogels and coatings. The previous studies show that the addition of BG improves the mechanical properties, biological activity and regeneration potential of the composites, and broadens the application of BG in the field of bone tissue engineering. By reviewing the recent BG researches on bone regeneration, the research potential of new materials is demonstrated, in order to provide a reference for future related research.
生物活性玻璃(BG)因其优异的生物学特性和无细胞毒性,已被广泛应用于人工骨支架的制备,它能够促进骨和软组织再生。然而,由于玻璃材料的脆性、机械强度差、易团聚以及结构不可控等问题,其在各个领域的应用受到限制。在这方面,目前大多数研究主要集中于通过冷冻干燥法、溶胶 - 凝胶法等将BG与有机或无机材料混合,以改善其机械性能和脆性,从而增加其临床应用并扩大其应用领域。本综述介绍了BG与天然有机材料、金属材料和非金属材料的结合,并通过支架、可注射填充剂、膜、水凝胶和涂层的发展展示了BG复合材料的最新技术和未来前景。先前的研究表明,BG的添加改善了复合材料的机械性能、生物活性和再生潜力,并拓宽了BG在骨组织工程领域的应用。通过回顾近期关于骨再生的BG研究,展示了新材料的研究潜力,以便为未来的相关研究提供参考。
