A method for forming a ceramic article useful as a bone substitute and having an outer surface defining a shape having a bulk volume and having open, interconnecting openings extending throughout the volume and opening through the surface, includes, providing an organic open-pore structure, coating surface of pores of the structure with a ceramic slip, pyrolyzing the organic structure to leave a ceramic structure having struts defining a plurality of interconnecting interstices, and providing within the interstices a porous osteoconductive composition exposed to the interconnecting openings. In a preferred embodiment, the ceramic slip includes a strong, supportive ceramic material and a separate osteoconductive material.
A method of forming a ceramic article useful as a bone substitute and having an outer surface defining a shape having a bulk volume and having open, interconnecting openings extending throughout said volume and opening through said surface, the method comprising providing an organic open-pore structure, coating surfaces of pores of the structure with a ceramic slip comprising zirconia, a binder, a solvent, fibers and/or whiskers, and hydroxyapatite, wherein the hydroxyapatite is present in an amount of up to about 50 volume percent based on the total volume of zirconia and hydroxyapatite, pyrolyzing the organic structure to leave a ceramic structure having struts defining a plurality of interconnecting interstices, and sintering the ceramic structure, said osteoconductive material being exposed to said interconnecting openings.
A method of producing a rigid reticulated article, comprising:
