THE INFLUENCE OF SAGITTAL MALOCCLUSION ON NASAL BREATHING DISORDERS

The main etiological factor in the formation of narrowing of the dental arches is a violation of the respiratory function and, as a consequence, an acquired bad habit - breathing through the mouth. The root causes that provoke the appearance of mouth breathing: hypertrophy of the adenoids and tonsils, rhinitis, curvature of the nasal septum, foreign bodies, nasal polyposis. The development of the upper respiratory tract and the facial skeleton are closely interconnected: mouth breathing leads to growth retardation and narrowing of the maxillary sinuses and upper jaw, which causes the formation of the Gothic shape of the palate. The etiopathogenetic mechanism for the development of narrowing of the dental arches is very diverse, but there is insufficient information on the relationship between narrowed dental arches and nasal cavities that determine changes in the facial skull.
