Title (EN) BONE CEMENT FORMULA AND BIORESORBABLE HARDENED BONE CEMENT COMPOSITES PREPARED WITH THE SAME
(FR) FORMULE DE CIMENT CHIRURGICAL ET COMPOSITES À BASE DE CIMENT CHIRURGICAL DURCI BIORÉSORBABLE PRÉPARÉS À L'AIDE DE CELLE-CI
Abstract: front page image
(EN)The present invention provides a bone cement formula having a powder component and a setting liquid component, wherein the powder component includes a calcium sulfate source and a calcium phosphate source with a weight ratio of the calcium sulfate source less than 65%, based on the total weight of the calcium sulfate source and the calcium phosphate source, and the setting liquid component comprises ammonium ion (NH4+) in a concentration of about 0.5 M to 4 M, wherein the calcium phosphate source includes tetracalcium phosphate (TTCP) and dicalcium phosphate in a molar ratio of TTCP to dicalcium phosphate of about 0.5 to about 2.5, and the calcium sulfate source is calcium sulfate hemihydrate (CSH), calcium sulfate dehydrate (CSD), or anhydrous calcium sulfate.
(FR)Cette invention concerne une formule de ciment chirurgical contenant un composant pulvérulent et un composant de prise liquide. Le composant pulvérulent contient une source de sulfate de calcium et une source de phosphate de calcium en une proportion en poids de la source de sulfate de calcium inférieure à 65 %, sur la base du poids total de la source de sulfate de calcium et de la source de phosphate de calcium, et le composant de prise liquide comprend l'ion ammonium (NH4+) à une concentration d'environ 0,5 à 4 M. La source de phosphate de calcium comprend le phosphate de tétracalcium (TTCP) et le phosphate de dicalcium dans un rapport molaire du TTCP au phosphate de dicalcium d'environ 0,5 à environ 2,5, et la source de sulfate de calcium est le sulfate de calcium hémihydraté (CSH), le sulfate de calcium dihydraté (CSD), ou le sulfate de calcium anhydre.
