Foam-like scaffolds for bone tissue engineering based on a novel couple of silicate-phosphate specular glasses: synthesis and properties

摘要: Glass–ceramic scaffolds mimicking the structure of cancellous bone were produced via sponge replication technique by using a polyurethane foam as template and glass powder below 30 μm inorganic phase. Specifically, SiO2-based complex composition its corresponding P2O5-based “specular” used materials for scaffolding. The polymeric was thermally removed powders sintered to obtain replica structure. investigated compared from structural, morphological mechanical viewpoint assessing their crystalline phases, volumetric shrinkage, pores content interconnection, strength. In addition, soaked in acellular simulated body fluid investigate vitro behaviour. have great potential reconstructive surgery because features, such shape, strength, bioactivity bioresorption, can be easily tailored according end use.
