Porous bioceramic composition for bone reconstruction

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 50 g). The scaffolds properties were characterized by x-ray diffraction (XRD), differential scanning calorimetry (DSC), scanning electron microscopy (SEM) and compression tests.
