POROUS BIOCERAMIC COMPOSITION FOR BONE REPAIR

摘要

The present invention relates to a porous bioceramic composition for bone repair and method of fabrication of the same. 3D-scaffolds were fabricated with a novel micro- and macro-architecture. Porous scaffolds based on dextrin, dextran, gelatin and biomineral (CaCO3) powder were fabricated by heating and freeze-drying methods. Fabrication of different compositions of porous scaffolds (20, 30 wt% of gelatin, 20, 40 wt% dextrin, 30, 40, 50, 60 wt% dextran bounder with the constant quantity of CaCO3 5Og). The scaffolds properties were characterised by x- ray diffraction (XRD), differential scanning calorimetry (DSC), scanning electron microscopy (SEM) and compression tests.
