METHOD OF MANUFACTURING A PROSTHESIS TO BE FIXED TO IMPLANTS IN THE JAWBONE OF A PATIENT, AND A SYSTEM FOR MANUFACTURING SUCH PROSTHESES

摘要

The invention provides a method for manufacturing a prosthesis to be fixed to implants in the jawbone of a patient. The method has as a characteristic feature that by means of at least one camera (40, 41, 42) arranged at the opened mouth of the patient, recordings are made of the implants (31-37) already fixed to the jaw of the patient from at least two different positions; these recordings are converted into electrical signals; by means of a photogrammetric method the electrical signals are processed using at least one calculating unit (47) for obtaining position and orientation information of the implants; and the position and orientation information is used for the highly accurate manufacture of at least a part of the prosthesis.
