Processing methods for making porous bioactive glass‐based scaffolds—A state‐of‐the‐art review

摘要

Abstract Bioactive glasses exhibit the unique ability of bone bonding, thus creating a stable interface by stimulating bone cells toward mechanisms of regeneration and self‐repair activated by ionic dissolution products. Therefore, 3D glass‐derived scaffolds can be considered ideal porous templates to be used in bone tissue engineering strategies and regenerative medicine. This review provides a comprehensive overview of all technological aspects relevant to the fabrication of bioactive glass scaffolds, including the fundamentals of materials processing, a summary of the conventional porogen, and template‐based methods and of recent additive manufacturing technologies, which are promising for large‐scale production of highly reproducible and reliable implants suitable for a wide range of clinical applications.
