The invention relates to an osseointegration implant having a three-dimensional structure, which at least partly covers the surface of the implant. The structure is of a latticework wherein the ratio of the volume of interstices of the latticework to the volume of the mass of the latticework is increasing towards the bone contacting face. Such a latticework matches the characteristics of natural bone and assures that the requisite amount of loading is transferred to the surrounding bone. This minimizes the stress applied to the interface between the host tissue and the implant eliminating atrophy resulting from either insufficient or excessive loading to result in both reduced surgical cost and complications associated with implantation.
