Laboratory Implant

Abstract

A method for the production of a dental implant with a post part which can be introduced into a jawbone and with a mounting part assigned thereto, on which a dental prosthetic piece can be mounted, is to allow the dental technician to perform a simple indexing of the mounting part while drawing on current procedural steps. For this purpose, the apical end of the mounting part is shaped in order to adapt the external cross-section of the mounting part to the internal cross-section of the post part.
