Abstract
An implant () has attachment and hole-insert parts () with an outer surface or outer surfaces having external layer arrangements (). The implant can be provided in a known manner with threads () on cylindrical and conical portions. The implant is made in principle in two production stages. In a first production stage, the outer surface or outer surfaces () of the implant are given a relatively high roughness value and/or a relatively high degree of porosity. In a second stage, the uneven or porous surface thus obtained is coated with an oxide layer () which can be uniform or can have different thicknesses along the longitudinal and/or circumferential directions(s) of the implant. In one embodiment, the oxide layer () can be coated with a bone-growth agent or bone-growth-promoting agent and/or calcium phosphate (), for example by means of chemical deposition, dipping or sputtering.
