  • Fluoride-containing Bioglass.TM. compositions
    Patent number: 4775646
    Abstract: A fluoride-containing bioactive glass composition suitable for bulk implant prosthetic devices and coatings for prosthetic devices, the bioactive glass compositions selected from glass formulations containing, by mole 46.1% SiO.sub.2, 2.6% P.sub.2 O.sub.5, 26.9% CaO and 24.4% Na.sub.2 O and glass formulations containing, by mole, 52.1% SiO.sub.2, 23.8% CaO, 21.5% Na.sub.2 O, 2.6% P.sub.2 O.sub.5 wherein, respectively, 30 to 50 molar percent and 40 to 60 molar percent of the CaO is substituted with CaF.sub.2. These fluoride-containing bioactive glass materials demonstrate high resistance to demineralization in physiological fluids as well as extensive apatite formation which shows a predominance of crystalline apatite of mixed phase character.
