Bioactive vitreous composition for bone implants, filaments made therefrom and method |
| abstract |
The invention relates to a bioactive vitreous composition for bone implantation which includes the following approximate percentages by weight of the following oxides: SiO2 from 40 to 55 %; P2O5 from 5 to 8 %; Cao (MgO) from 20 to 40 %; Na2 (K2O) from 20 to 30 %. The composition can be reduced to filaments without becoming ceramic by virtue of the addition of a total of not more than 9 % by weight of K2O and Al2O3, the percentage of Al2O3 being from 0.5 % to 2.5 %. The filaments thus obtained can be used to prepare products for bone implantation in the form of bundles of filaments, gauzes, nets or other fabrics, felts, "cotton-wools" and the like. The filaments can be reduced to particles of powders for the application, inter alia, of a coating layer of the vitreous composition to a permanent metal prosthesis. |
