<p>Novel non-crystalline, porous bioactive glass and ceramic materials that permit the in vitro formation of bone tissue when exposed to a tissue culture medium and inoculated with cells are disclosed. The present invention also discloses bioactive glass materials treated such that when the glass is in contact with anchorage-dependent cells, there is enhanced cell attachment and cell function. Expeditious tissue growth occurs in vitro or in vivo. The glass material disclosed is preferably formed from SiO2, CaO, Na2O and P2O5, although other oxides may be included, and is most preferably prepared by melting the constituents, cooling and pulverizing the resulting glass, and then forming and hot pressing the powder. The glass of the present invention may be formed to produce templates that are useful for various indications, as well as granules that may be formed into a paste.</p> |
