METHOD AND DEVICE FOR PRODUCING ARTIFICIAL DENTURE Russian patent published in 2000 - IPC

FIELD: medicine; medical engineering. SUBSTANCE: method involves introducing measuring electrode into implant fixed in mandible bone. The electrode is tightly sealed providing galvanic contact with the implant. Resistance between the implant and surrounding tissues is measured with the ohmmeter, the measuring electrode, auxiliary electrode and additional electrode. Then, the measuring electrode is removed and gingiva former is set into the implant. The gingiva former has controllable electric power supply source which negative pole is galvanically connected to the implant and the positive one is connected to gingiva former cover. Electric stimulation of tissues surrounding the implant is carried out with electric current of 5-50 mcA and concurrent exposure to magnetic field having inductance of 0.1-0.3 Tesla units. The gingiva former is periodically removed in every 5-10 days and substituted with measuring electrode. Resistance is measured with a described method and then, the gingiva former is once more fixed on the implant. Current and magnetic field action is continued with the same current and magnetic field parameters. The dental prosthesis is fixed on the implant by means of a through metal pin built into the dental prosthesis providing galvanic contact between them. The tissues surrounding the implant are continuously subjected to electric stimulation through an additional electrode applied from outward to a pin by means of external electric power supply source with mean current value of 5-50 mcA applied 1-2 times a day and concurrent exposure to magnetic field having inductance of 0.1-0.3 Tesla units applied daily 1-2 times a day during at least 10 days long, in periodically controlling resistance between the implant and surrounding tissues. The gingiva former of the device additionally has an internal cavity and cover. Controllable electric power supply source is placed inside of the cavity. Its negative pole is galvanically connected to the gingiva former casing and the positive one is connected to the cover. The casing and cover are electrically insulated one from another. External surface of the gingiva former is coated with dielectric. The dental prosthesis is additionally provided with a through metal pin having a member for fastening to the implant and outlet to the working surface of a tooth. The device also has measuring, additional and auxiliary electrodes. EFFECT: accelerated osteointegration; prevented and eliminated inflammation processes in the implantation area. 10 cl, 5 dwg
