The aim of this study was to obtain a biodegradable porous calcium phosphate implants as synthetic bone graft substitutes. Calcium phosphate used in this study consisted of hydroxyapatite and anhydrous dicalcium phosphate. Four different types of porous calcium phosphates were made on addition of polyurethane by sinter processing. The X-ray diffractometry revealed that ß-tricalcium phosphate is a dominating phase. Experimental results showed the pore microstructure of the as-sintered bodies to consist of the macropores and micropores. Surface morphology analysis and porosity evaluations were performed. The variation in the compressive strength, elastic modulus and dissolution behaviour of immersed synthetic bone grafts in simulated physiological solutions was investigated.
