The invention relates to a body joint replacement titanium implant comprising one or several base bodies. In known titanium implants, there is a risk of loosening due to the anchoring of the implants in the bone at points where an optimum bone regeneration is undesirable. The functioning of the joints of the implants can be impaired by coalescing with connective tissue. The novel titanium implants avoid said problems by virtue of the fact that parts (3, 4, 8, 9) of the implant are provided with an anodically (type II) oxidised layer containing oxygen and silicon.
L'invention concerne un implant en titane servant ~ remplacer une articulation du corps et comportant un ou plusieurs corps de base. Les implants en titane connus pr~sentent le risque de subir un rel~chement provoqu~ par le fait qu'ils sont ancr~s dans des zones de l'os oÕ une r~g~n~ration osseuse optimale n'est pas souhait~e. En outre, la fonction des articulations des implants risque d'Útre alt~r~e par leur adh~sion au tissu conjonctif. Les nouveaux implants en titane selon l'invention suppriment ces inconv~nients. A cet effet, des parties (3, 4, 8, 9) de l'implant pr~sentent une couche ayant subi une oxydation anodique (de type II) et contenant de l'oxygne et du silicium.
