Bioresorbable, mineralised material for filling osseous defects

Abstract

A bioresorbable and mineralized material for filling osseous defects includes a native and/or renatured collagen matrix of congregated collagen chains, in which essentially only a surface of the congregated collagen chains is mineralized. A shaped article for filling osseous defects includes such a material. A method for producing a shaped article for filling osseous defects from a liquid medium, includes the steps of deposition of a mineral substance, preferably from its dissolved ionogenic components, on a collagen matrix, precipitation of the mineralized collagen matrix, separation of the mineralized collagen matrix, transfer of the mineralized collagen matrix to a suspension, transfer of the suspension to a mold defining the shaped article, and freeze-drying of the suspension in the mold.
