CA 2689319

The invention relates to a surface of a metal implant based on titanium, to be inserted into osseous tissue, comprising substantially pure titanium oxide and having a thickness of between 8 and 50 nm. The invention also relates to a method for producing said surface, and to a metal implant comprising same. The surface has a good micrometric roughness, a composition which is practically free of impurities, and a thickness which is approximately three times that of conventional surfaces, said characteristics imparting very good osteointegration properties to the implant.

L'invention concerne une surface d'implant métallique à base de titane destiné à être inséré dans le tissu osseux, comprenant de l'oxyde de titane sensiblement pur et présentant une épaisseur de 8-50 nm. L'invention concerne également un procédé permettant d'obtenir cette surface, ainsi que l'implant métallique présentant cette surface. Ladite surface présente une bonne rugosité micrométrique, ainsi qu'une composition pratiquement exempte d'impuretés et une épaisseur qui correspond approximativement au triple de celle des surfaces classiques, caractéristiques qui lui confèrent de très bonnes propriétés d'ostéointégration.
