METHOD FOR PREPARING A BONE FILLER MATERIAL AND MATERIAL PREPARED BY SUCH A METHOD

摘要

The invention relates to a method for preparing an osteomimetic material from which an endosseous implant for medical or veterinary use is made, said method including the steps of: i. preparing (210) a homogeneous mixture consisting of a biocompatible thermoplastic polymer and beta-tricalcium phosphate (ßTCP), ii. Subjecting said mixture to an injection or extrusion molding operation (220) on a screw machine, at an injection temperature at least equal to the fusion temperature of said polymer and at a pressure of between 70 MPa and 140 Mpa so as to convert said tricalcium phosphat into a non-stoichiometric calcium apatite 3(Ca3(PO4)2)(OH)2Ca similar to that of bone. The invention also relates to a material prepared by such a method and to an endosseous implant made of said material.
