Ceramic and ceramic composite materials and devices were developed for specific maxillofacial applications. These applications included: Replacement of hard tissue voids in low stress areas with a phosphate-bonded alumina-foamed ceramic and a calcium aluminate-bonded alumina foam; and development of porous ceramic-coated metallic devices for stabilization of mandibles with avulsed segments. Efforts to date have been rewarding. Using the rhesus monkey for all experimental implant work, incorporation of porous ceramic foam ...
