Title
(EN) A BIOACTIVE GLASS FOR USE IN CONDITIONS RELATING TO BONE INFECTIONS
(FR) VERRE BIOACTIF DESTINÉ À ÊTRE UTILISÉ DANS DES PATHOLOGIES LIÉES AUX INFECTIONS OSSEUSES
Abstract
(EN)
The present invention relates to a bioactive glass having the composition of SiO2 44-65 wt-% of the final total weight, Na2O 5-26 wt-% of the final total weight, CaO 10-25 wt-% of the final total weight, K2O 0-1 5 wt-% of the final total weight, MgO 0-6 wt-% of the final total weight, B2O3 0-4 wt-% of the final total weight, and P2O5 0-7 wt-% of the final total weight, for use in the long- and short-term prevention and/or treatment of conditions relating to or caused by bone infections, provided that the total amount of Na2O and K2O is 10-30 wt-% of the final total weight, and that any source of oxygen capable of releasing oxygen in the form of molecular oxygen or reactive oxygen species, is absent.
(FR)
La présente invention concerne un verre bioactif qui possède la composition suivante : SiO2 représentant 44 à 65 % poids du poids total final ; Na2O représentant 5 à 26 % poids du poids total final ; CaO représentant 10 à 25 % poids du poids total final ; K2O représentant 0 à 15 % poids du poids total final ; MgO représentant 0 à 6 % poids du poids total final ; MgO représentant 0 à 4 % poids du poids total final ; et P2O5 représentant 0 à 7 % poids du poids total final. Ledit verre est destiné à être utilisé dans la prévention à long terme et à court terme et/ou le traitement de pathologies liées à, ou provoquées par, des infections osseuses, à condition que la quantité totale de Na2O et de K2O se situe entre 10 et 30 % poids du poids total final, et que toute source d'oxygène capable de libérer de l'oxygène sous forme d'oxygène moléculaire ou espèce réactive de l'oxygène soit absente.
