Beschreibung
Zusammenfassung:	Provided are a bone graft composition and a preparation method thereof, and more particularly, a bone graft composition provided in the form of a putty formulation by mixing calcium phosphate compound particles with hydrogel, having excellent physical properties, which is easy to inject, and which maintains its structure even in an in vivo environment after implantation, thereby enabling sustained release of a drug loaded therein. L'invention concerne une composition de greffe osseuse et son procédé de préparation, et plus particulièrement, une composition de greffe osseuse se présentant sous la forme d'une formulation de mastic obtenue par le mélange de particules d'un composé phosphate de calcium avec un hydrogel, qui présente d'excellentes propriétés physiques, qui est facile à injecter et qui conserve sa structure même dans un environnement in vivo après implantation, ce qui permet une libération prolongée d'un médicament chargé à l'intérieur de celle-ci.
