  • Method and apparatus for the manufacture of dental protheses
    Patent number: 4734173
    Abstract: The present invention relates to a method and an apparatus for the manufacture of dental prostheses by means of an electroerosion process by using two template electrodes for erosive excavation. The dental prosthesis to be inserted is made directly from solid material which has not been previously worked. The negative templates of the dental prosthesis contained in the template electrodes can also be made by the electroerosion method. The manufacture of the dental prosthesis can be accomplished by a simultaneous movement of the two template electrodes or by manufacture of the two form halves of the dental prosthesis at different times.
