ABSTRACT:
Disclosed are useful and unique glass phosphate cement compositions and methods for their use as surgical implant materials to fill cavities in bone and canals in teeth. The cement compositions consist of glass powders having a range of chemicals including P.sub.2 O.sub.5, CaO, SrO and Na.sub.2 O in combination with an aqueous liquid and with or without therapeutic agents. Mixing the powder and liquid results in a hardening reaction. When the cement is implanted into hard tissue, it serves as a filler/graft material and along with the release of leachable constituents it can assist in the healing and maintenance of healthy bone.
