FIELD: medicine.
SUBSTANCE: invention relates to medicine, specifically to dentistry, and is intended for use in planned movement of upper and lower jaws with orthodontic activator. At the first stage, performing oral cavity 3D scanning, loading the obtained data into the CAD/CAM program and setting the jaw extension in the CAD/CAM program, further, the dental arch extension is set on the lower jaw, and then on the upper jaw, then the position of the upper jaw dental arch is levelled in relation to the position of the lower jaw dental arch position to obtain planned 3D model of the jaw. At the second stage, a structure of planned 3D model of the jaw is modelled with orthodontic elements. At the third stage, the structure of planned 3D model of the jaw with orthodontic elements obtained at the second stage is sent to 3D printer for printing. At the fourth stage, the structure printed at the third stage of 3D model of the jaw planned at the second stage with orthodontic elements is crimped with upper and lower trays made of a biocompatible material on a thermal vacuum moulding machine. At the fifth stage, the upper and lower trays made of a biocompatible material prepared at the fourth stage are inserted into the patient.
EFFECT: by individual modelling, as well as by the presence of cap beads, tongue guides, buccal pilots and trapezoidal guides in the structures, the method enables creating the optimum strains in the cap structure sufficient for the preset correction of the upper and lower jaw position, and eliminating the tongue parafunction.
