摘要

An improved orthopedic or dental implant is formed so that at least its bone contacting surfaces are comprised of a biocompatible organic polymer substituted with salt-forming sulfur oxyacid groups or biocompatible salts thereof. In addition, a method of promoting bone tissue deposition and adhesion has been found which utilizes an implant having a biocompatible organic polymer substituted with carbon, sulfur or phosphorous oxyacid groups or sales thereof on its bone contacting surfaces. Such oxyacid substituted polymers have been found to promote interfacial osteogenesis, to enhance the rate of bony growth into porous implant surfaces, and to foster direct chemical bonding of the implant surface with the biological polymers present in developing bone tissue.
