Abstract :
The aim of this study was to obtain a new porous tricalcium phosphate as a synthetic bone scaffold. Porous bioceramic was fabricated by a foam-casting method. By polyurethane foam and slurry containing Hydroxyapatite/Dctacalcium phosphate anhydrous (HA/DCPA) powder, water and additives a high porous structure with 66±5% was created. The porous bioceramic possesses a compressive strength of (10.7±1.7) MPa and E-modulus of (2.3±0.3) GPa. Regarding these properties this synthetic samples could be used as a cancellous bone scaffold.
