FIELD : medicine.SUBSTANCE : invention relates to the field of medicine, in particular to dentistry, and can be used as a removable device in the correction of teeth of adolescent and adult patients, correction of occlusion, treatment of periodontal diseases, teeth whitening and other purposes. Myofunctional tooth corrector is made of a single structure made from an elastic material, including the vestibular lip, the lingual border and the occlusal base. In the occlusal base, the size between the ends is configured to be equal to the size between the upper alveolar ridges of the patient' s normal occlusion. Size from the middle of the outer arch to each end of the occlusal base is arranged to be equal to the size from the middle of the central incisors to each end of the upper alveolar crests of the patient. Thickness of the occlusal base is made within 1–5?mm, in the vestibular bump, the height is 10–20?mm with a uniform increase in the occlusal base by 0.5–5?mm to the ends, in the lingual side, the height is 7–15?mm with a uniform decrease to the ends of the occlusal base. There are thickening on the inner side of the lingual border. On the vestibular side, a pattern in the form of a decorative dentition is shown. Myofunctional tooth corrector is made by casting the material into a mold or by printing on a 3D printer.EFFECT : invention makes it possible to reduce the cost of manufacturing the myofunctional tooth corrector, to simplify its use in the correction of teeth, bite correction, gum treatment, teeth whitening without damaging the health of the gums and enamel of the teeth.3 cl, 2 dwg
