Abstrakt:	The processes of neuroplasticity of the motor cortex of the brain were evaluated in the treatment of 20 (12 women and 8 men) patients aged 18-35 years (22.5±1.5 years) with distal occlusion using functional magnetic resonance imaging (fMRI), as well as comparison of surface myography (EMG) data to assess the adaptive capabilities of the tooth-jaw system and the central nervous system against the background of orthodontic correction. Correction of distal occlusion was carried out using ceramic braces 'Damon' (f. 'Ormco', USA). The advancement of the lower jaw forward with bite enhancement was carried out using the Twin force device ('Ortho Orgonizers GmbH', Germany). The study was conducted in five stages: 1) before orthodontic correction; 2) before installing the Twin force device; 3) after anterior displacement of the lower jaw and bite enhancement on the Twin force device; 4) after removing the brackets; 5) 1.5 months after the treatment. FMRI proved to be a useful tool for orthodontic treatment efficacy assessment and neuromuscular adaptation of maxillofacial structures to changing functional status.
