FIELD: medicine.;SUBSTANCE: invention refers to medicine, dentistry, namely to orthodontics, and aims at making a sequence of trays for normalising a position of the upper jaw fragments and alveolar process in children suffering the cleft lip and palate. The upper jaw impression is recorded. A cast model is made and scanned in a computer tomography scanner; a digital copy of the model is reproduced by means of 3D modelling software application; the jaw fragment is displaced successively at an increment of no more than 2 mm. This creates a sequence of 6-12 digital models with successive displacement of the fragment. The information is stored on any electronic media in any 3D printable format. The models printed in 3D printer are used to make the sequential trays.;EFFECT: by making the 3D models and using them for making the correction trays in compliance with the pre-set parameters, the method enables simplifying the laboratory stage and increasing the displacement accuracy, thereby improving the quality of treatment.;7 dwg
