(57) Summary A novel amorphous porous bioactive glass and ceramic material is disclosed that allows in vitro formation of bone tissue when inoculated with cells upon exposure to tissue culture medium. The present invention also discloses a method of treating the bioactive glass material to control the pH such that bone tissue growth occurs in vitro when the glass is exposed to a tissue culture medium and then inoculated with cells. Glass materials disclosed are preferably formed from SiO 2, CaO, Na 2 O and P 2 O 5, porous amorphous structure, and most preferably, to melt the components, cooled, and the product It is made by crushing the glass to be blown and then foaming and hot pressing the powder. The glasses of the invention can be shaped to produce granules that can be templated as well as pastes that serve a variety of applications. |
