Abstract: 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 plants 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.
