process for the production of a prosthesis in a patient with jaw fixed implants is fastened, and device for the manufacture of such implants

摘要

The invention provides a method for manufacturing a prosthesis to be fixed to a plurality of implants in the jawbone of a patient. The method has as a characteristic feature that by means of at least one camera arranged at the opened mouth of the patient; images of the implants already fixed to the jaw of the patient are recorded from at least two different positions; these images are converted into electrical signals by at least one camera; by means of a photogrammetric method the electrical signals are processed using at least one calculating unit for obtaining positions and orientation information of the implants; and the positions and orientation information is used for the highly accurate manufacture of at least a part of the prosthesis.
