The invention discloses a novel implant provided with a macroporous surface on the top surface, and a method for the production of such a metallic and/or ceramic implant having a textured, particularly porous, surface for the at least partial insertion in hard tissue, such as in a bone, and/or into soft tissue. The implant is produced as a green compact, at least in sections, using a cold isostatic pressing, casting, and/or injecting (CIM, MIM) with subsequent sintering to obtain an implant, and is particularly characterized in that the surface is modified and/or prepared before sintering such that a macroporous surface is present after sintering without requiring any finishing.
L'invention concerne un nouvel implant doté d'une surface macroporeuse au niveau de la surface, ainsi qu'un procédé de fabrication d'un tel implant métallique et/ou céramique présentant une surface structurée, en particulier poreuse, pour une pose au moins partielle dans les tissus durs comme dans un os et/ou dans un tissu mou. L'implant est fabriqué au moins dans certains endroits à l'aide d'un pressage isostatique à froid, d'un coulage et/ou d'une injection (CIM, MIM) d'un corps vert comportant des frittages attachés en un implant, et est en particulier caractérisé en ce que la surface devant le frittage est ainsi modifiée et/ou préparée, en ce qu'il présente, après le frittage sans traitement supplémentaire, une surface macroporeuse.
