Hydroxyapatite is a ceramic enabling of fixing bioactive, cells invasion and nutrients, which promote tissue regeneration. In these work, dimensional hydroxyapatite stage using gel-casting technique combined with infiltration of polymer foams, with a percent solids of 40% and three different monomers were prepared. The stages surface morphology and the pore size were characterized by scanning electron microscopy (SEM), porosity and interconnectivity was determined by immersion tests and mechanical compression tests were performed. The results obtained show that the stages have opened and interconnected porosity with a pore size of approximately 300 microns and low mechanical strength of 0.1 MPa as compared with that of human trabecular bone.
