Hussein BF, Alfaham HM, Abass A., Bioceramic scaffold for bone reconstruction, Onl J Vet Res., 21(11):733-727, 2017. Porous biodegradable scaffolds for bone remodeling reconstruction made with 10-20g crab shell powder, 40-50g dextrin, 10-20g Al-kharit and 20-30g gelatin are described. Scaffolds were constructed by heat processing and scanned by electron microscopy for structural characterization and particle size. The 3D-Scaffolds with controlled porosity and adequate strength were biodegradable and biocompatible. In water immersion, the scaffolds persisted 10-30 days without dimensional or visible surface degradation. X-ray diffraction showed CaCO3 like Graphite crystals at 200nm. Scanning Electron Microscopy (SEM) showed macro-microspore 25 μm-90 μm with homogeneous interior crab shell powder (calcium carbonate) microcrystal polygonal pores.
