<p>The object of the invention is to provide an implant material comprising a bioactive and degradable and absorbable organic-inorganic complex porous article and a production method thereof. <??>The invention is, an implant material comprising an organic-inorganic complex porous article which is a biodegradable and bioabsorbable bioactive porous article in which a bioactive bioceramics powder is uniformly dispersed in a biodegradable and bioabsorbable polymer, wherein it has continuous pores and the bioceramics powder is partly exposed to the pore inner surface or the pore inner surface and the porous article surface, and a method for producing an implant material comprising an organic-inorganic complex porous article, characterized in that a nonwoven fabric-like fiber aggregate is formed from a mixed solution prepared by dissolving a biodegradable and bioabsorbable polymer in a volatile solvent and dispersing a bioactive bioceramics powder therein, this is formed into a porous fiber aggregate molding by compression-molding it under heating, the fiber aggregate molding is soaked in the volatile solvent, and then said solvent is removed. <IMAGE></p> |
