  • Process for the manufacture of prosthetic implants
    Patent number: 5954768
    Abstract: A process for the manufacture of prosthetic implants with a roughened tissue ingrowth surface consists in obtaining an even surface roughening in the form of balls in which the balls made integral with the implant all have the same diameter and have been obtained by uniformly distributing the balls through a mesh onto the surface to be roughened. Such implants have fewer risks after implantation because the bony tissue ingrowth is on a more uniform surface.
