A device for dental electroanalgesia includes a low-frequency electric pulse generator with an electric pulse repetition frequency setter, an electric pulse front discriminator, an electric pulse shaper, a current amplifier, a transformer, and an electric pulse amplitude regulator electrically connected to electrodes. The electrodes are placed on a corresponding reflexogenic zone of the auricular concha and on the mucosa of the alveolar process of one of the jaws within the area of the projection of the root apices of the patient's teeth. A temperature snesor is placed on the patient's face skin in the area of segmental innervation of the patient's dental tissues and is connected to an electric pulse duration regulator whose output is connected to the input of the electric pulse shaper.

Device for dental electroanalgesia

The dental prosthesis comprises a base from a durable corrosion-resistant metallic alloy and at least one external decorative layer. The external decorative layer is made of a harder material than the base and comprises nitrides, oxynitrides, carboxynitrides, cyanonitrides and/or oxides of metals of the subordinate subgroup of Group IV of the periodic system. The thickness ratio of the external decorative layer to the base is equal to 1:10-200 respectively. In the case where the dental prosthesis base comprises a structure of soldered members from a durable corrosion-resistant metallic alloy, the method for making the dental prosthesis comprises manufacture of the base by soldering members of the dental prosthesis from the abovementioned alloy into an integrated structure. Then the zone of the soldered juncture or the entire structure is coated, by electroplating or vacuum technique, with an additional layer from cobalt, nickel, molybdenum, chromium or zirconium, or from nitrides of chromium or molybdenum. The thickness ratio of the additional layer to the external decorative layer is equal to 0.5-1:1 respectively. Thereafter, the external decorative layer is deposited by vacuum technique.
