Abstract: In a process for the production of a dental implant wherein the tooth root region of a natural tooth, which region has been removed from a tooth socket or the like cavity in the jaw, is copied or modelled on an implant blank comprising a biologically compatible, non-resorbable material, wherein the modelling operation is effected in particular by copy-milling, the cross-sectional dimensions of the tooth root of the natural tooth are extended in predetermined zones by double a gap dimension. In addition the basic anatomical shape of the implant is produced by contact-less sensing of the tooth root of the natural tooth by a laser beam or sonography and the gap dimensions are added as calculation values.
