FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely, to orthodontics. 3D scanning is performed to obtain 3D models of the alveolar ridges and the palate of the newborn child. The trajectory of convergence of the non-joined segments of the jaw and the required amount of steps for convergence are determined. Obturators are made for each step of convergence of the non-joined segments of the jaw. The obturators for the convergence of the non-joined segments of the jaw are installed consecutively. 3D scanning is therein performed by means of an intraoral scanner, and the results of scanning are transmitted to a computer. Individual aligners based on the obtained computer 3D models of the alveolar ridges and palate of the child are used as obturators. The amount of individual aligners made corresponds to the amount of convergence steps calculated on the basis that the intracapillary pressure in the areas of the impact zones of the aligners should not exceed 26 g/cm2, and the total time of preparation for the surgery should not exceed 7 months. The convergence trajectory is therein selected using a computer simulation program.
EFFECT: method allows for an increase in the accuracy of manufacturing a set of consecutive orthodontic aligners for most comfortable preparation of the child for the cleft palate and lip closure surgery.
