Method for producing open-porous bone implants made from fibers, with freely accessible guide structures made from fibers, which are formed from a biocompatible metal or metal alloy

Abstract

In the method for producing open-porous bone implants with freely accessible guide structures made from fibers, which are formed from a biocompatible metal or metal alloy, long fibers are superimposed in multiple layers, each in the form of a nonwoven, in which the fibers in each layer are arranged in a mutually preferred axial direction. Needling is carried out in at least one of the layers, by means of which individual fibers of the respective layer are aligned in an axial direction which differs by at least 60° from the preferred axial direction in which the other fibers of the layer are aligned. The superimposed layers are materially fitted to one another point by point via sinter bridges on fibers by sintering in a heating device.
