摘要

Usage: medicine, dentistry, orthodontics. The essence of the utility model: the apparatus consists of crowns for the first permanent molars of the upper jaw, which on their occlusal surface have a thickening with no simulated architectonics of the chewing surface of the supporting teeth, that is, with a flat lower surface, on the buccal the surface of which the buccal tubes and an element made in the form are soldered, as shown in position 4 of figure 1, and located strictly parallel to the dentition of the upper jaw to prevent nadku When lowering the jaw back or inward, the palatal arch is soldered to their palatal surface and half-crowns to the lower first permanent molars, the lever and vestibular arch with M-shaped bends are soldered to the buccal surface, and the lingual arch with omega loops is soldered to the lingual surface. Technical result: the ability to use the device with minor turns of molars in the absence of the need to expand the dentition, the exclusion of protrusion of the incisors of the lower jaw due to the addition of stibulyarnoy arc on the lower jaw, the use of the device in patients with type giperdivergentnym facial skeleton due to the intrusion of the first permanent molars of the upper jaw. 5 ill.
