METHOD FOR CORRECTION OF COMBINED DENTOALVEOLAR ANOMALIES IN CHILDREN IN PERIODS OF REPLACEABLE AND FORMING PERMANENT BITES Russian patent published in 2024 - IPC A61C7/00 A61B17/24 

FIELD: medicine; dentistry.

SUBSTANCE: invention is intended for use in orthodontics for correction of combined dentoalveolar anomalies in children. Upon admission, a child is diagnosed with a malocclusion, the corresponding shape and size of the dentoalveolar arches, the position of the erupting teeth, condition of muscles of lips, cheeks, tongue, proper breathing, speech, swallowing and chewing. In accordance with the detected pathology, a staged treatment is prescribed: at the first stage, plaster models of the upper and lower jaws and a bite block are made on the upper jaw model, under the doctor’s control, the patient sets the lower jaw in the normal anatomical position and fixes it with the help of the bite block, the models are also matched with the help of the bite block, for 6–8 months, elimination of upper dentition deviation by means of screw by means of expansion to creation of individual normal width, then the upper dentition is elongated with the help of screws to create a place for eruption of separate teeth for the specified time daily around the clock, simultaneously with the help of functional tests it is controlled by conformity of free closure of lips along Klein's line and movements of tongue during breathing, speech and swallowing to norm; after which at the second stage within 2 months the patient is prepared for myogymnastics: interference from frenulum of lips and tongue is eliminated, using orthopantomography is determined and, in case of abnormal resorption of roots of temporary teeth, they are removed, then, by means of orthopantomography, the position and direction of eruption of permanent teeth is determined, with the help of a diagnostic model, the preservation of conditions in the dentition is controlled for the complete eruption of permanent teeth, their position in the dentition is corrected with the help of orthodontic appliances; at the third stage for 2 months, the patient under the control of treatment results performs static myogymnastics once day for 25–30 minutes at intervals of 2–3 minutes, strengthening the muscles that move the lower jaw to the anatomically correct position, surrounding the dentoalveolar arches, the muscles of the lips, cheeks and tongue to correct lip closure, normalization of tongue position, nasal breathing type, speech clarity, efficiency of chewing, somatic swallowing; wherein once every 1.5–2 months, the correction of deviations from the anatomical norm of the occlusion, dentition, position of the teeth, functional disorders is monitored, then the plaster models of the jaws are again made, are compared with the models before treatment, and in case of insufficient occlusion correction, abnormalities are additionally eliminated according to the same scheme.

EFFECT: method, due to strictly sequential stages of exposure in complex, including myogymnastics, reasonable modes, frequency, duration of exercises, control of treatment using defects detected on orthopantomography and by models in dynamics of comparison of changes once a month, allows increasing therapeutic effect of combined dentoalveolar anomalies correction, reducing correction period, providing reliability of good quality of achieving normal anatomical ratios.
