A gravity sintering fabrication technique has been developed for producing Co-Cr-Mo alloy dental implants having a porous coating on the root portion. This process allows for control of pore structure enabling ingrowth of either bone or fibrous tissue. The microstructure and mechanical properties of these materials have been determined.
