<p>A surface structure is produced on an implant surface by means of cutting work in which parts of a tool are pressed, during surface production, against the implant or against a blank which is intended to form the implant. The parts and the implant/blank are assigned controls which give rise to mutual displacements between the parts and the implant/blank in order to form the surface structure. The controls are initiated by means of first apparatus for identification of the implant situation and production of parameters for bone types and implant types. The controls are transmitted to second apparatus controlling the tool which are designed to work with a suitable movement function, for example oscillator function, roller function, etc., by means of which said parts cooperate with the implant/blank and are caused to execute the movements. The controls are chosen so as to produce cup-shaped depressions arranged alongside one another and separated by intermediate ridges. The invention also relates to an implant with such depressions.</p> |
