ABSTRACT:
The invention is concerned with a method and an equipment for forming prosthetic tooth structures for fastening to implants, where at least one pattern is produced from the portion of a patient's jawbone containing the implants and pattern sockets of metal is arranged in it at a place which corresponds with the position of the implant in the patient's jawbone, and a prosthetic tooth structure is produced from metal with the aid of the pattern. The particular feature of the invention consists in the provision of implant electrodes of metal, the heads of which correspond essentially with the heads of the implants, being fastened releasably in the pattern sockets in lieu of dummy implants, and the pattern socket and/or the implant electrodes as well as the prosthetic tooth structure are connected to a spark erosion equipment in such a way that the pattern sockets and/or the implant electrodes form the one electrode and the prosthetic tooth structure the other electrode, and the pattern and the prosthetic tooth structure are moved one against the other, and in so doing the prosthetic tooth structure is eroded so that it is adapted to the heads of the implants.
