METHOD FOR PRODUCING AN ELONGATE SUPPORTING PART IN A REPLACEMENT CONSTRUCTION, AND SUCH A SUPPORTING PART MANUFACTURED USING THIS METHOD

摘要

A supporting part (28) for a denture (21) will be produced in one piece, or in two or more partial pieces which are assembled, Surface-reading members (22) are in this case used for forming digital representations (23) which are supplied to computer equipment, by means of which machining information items (25) are generated. The supporting part original is produced with the aid of working models, and a blank is applied in holders which can be applied in a machining device which is controlled by the machining information. Electro-erosion tools are created with the impression model/working model. The tools include electro-erosion electrodes at positions for the dummies for the implants or their spacing members. Using the electro-erosion equipment, the machined blank is provided with recesses for bridge parts which are to bear against the implants or their spacing members. The contact surfaces on the bridge parts and the connection surfaces on the implants bear against each other with great precision, and the inclinations of the bridge parts coincide with the inclinations of the implants or are slightly displaced in parallel with respect to the latter.
