Description

This invention relates to medicine, specifically to orthodontics, and is intended for the treatment of prognathic bite.

The purpose of the invention is to reduce the duration of treatment for prognathic bite.

FIG. 1 shows the device, top view; in fig. 2 - the same, side view.

A device for the treatment of prognathic bite contains the palatal base plate 1 on the upper jaw, the vestibular arch wire 2 and the Adams clamer 3. In addition, the palatine basic plate 1 is provided with an active wire element 4, made in the form of a symmetrical arcuate structure containing six half-loops 5, located in its central part, bent in a vertical plane according to the shape of the lamely surface of the lower front teeth. Half-heels 5 pass from each side into straight sections 6 with one-and-half spirals 7 at their ends. In addition, the device includes a palatine wire bundle 8 and a labial pad 9 for retracting the lower lip from the lower tooth row.

The device is used as follows.

After fixation of the apparatus on the upper jaw, when the oral cavity is closed, the child pushes the lower jaw and the lower dental row is fixed in the previously defined constructive bite with an active wire element 4. At the same time, the entire lower dental row receives a uniform load. It should be noted that the design does not allow the lower jaw to be displaced posteriorly, since the arcuate structure of the apparatus, which is located on the loud side of the lower posterior teeth, prevents this movement. After the teeth are closed, the lower dental row presses on the vertical wire half loops 5, in turn, on the straight section 6 of the arcuate design, and this load is partially absorbed by the spirals 7 in the sixth teeth, and part of the load is transferred to the upper dental arch. A flattening of the anterior portion of the upper dental row is observed (plastic is preselected from the palatal surfaces of the upper anterior teeth). Vertical

the half loops 5 in the region of the lower anterior teeth play the role of a plane to hold the lower tooth row in the extended position, and specifically to hold the lower anterior teeth. Unlike the inclined plane, where the lower incisors and canines are affected by the resultant two forces (vertical and horizontal) in this apparatus, the forceps of the lower anterior teeth are affected by one force in the sagittal direction, and this force is evenly distributed over the entire lower tooth row, so as it is, the half-strap 5 is transmitted to the wire arc 2 in the region of the lower posterior teeth, and the spirals 7 bent in the region of the sixth teeth are held in a spring-loaded state, the entire arc 2 and a partial load is transferred to the upper bnoy row. Another force in the vertical direction of the front cutting edges of the teeth are obtained by contact with the palatal surface of the upper front teeth. Considering that the majority of children with prognathic bite have impaired function not only during swallowing (infantile type), but also in the state of “rest of the lower jaw and speech,” lingual vertical half loops 5 play the role of a flap for the tongue and eliminate its harmful effects. the position of the upper anterior teeth (their protrusion), and when swallowed, the tip of the tongue slides along the half loop of 5, rises and lies in the region of the upper anterior teeth from the palatal side.

The vertical half-teeth 5 can be used to adjust the position of the lower anterior teeth (their loud position, inclination).

The labial plastic pilot 9 rejects the lower lip from the lower tooth row, which leads to a change in the myodynamic balance between the tongue and the circular muscle of the mouth. In addition, when the lips are closed, the tone of the circular muscle of the mouth increases.

Thus, this design shortens the treatment time for prognathic bite and also normalizes the function of the tongue.
