Introduction. Distal bite is one of the most common problems in orthodontic practice and is accompanied by certain morphological, functional and aesthetic changes: a violation of the dynamic balance of the muscles of the perioral region and tongue, in which a number of functions of the child suffer: there are violations of the function of external respiration, speech, chewing and swallowing functions. Purpose of the work. Study of the features of anthropometric and telerentgenographic parameters in patients aged 7-13 years with complex forms of distal occlusion with normal and impaired external respiratory function. Research methods. We examined 231 children aged 7 to 13 years with distal bite, in the period of variable bite, at the peak of growth (CS3 and CS4 – puberty stages). The peak of puberty was determined by hand-wrist X-ray analysis, CVM (cervical vertebra maturation) method, and chronological age. Cephalometric analysis with determination of anatomical landmarks, lines and parameters for assessing the base of the skull, jaw position, hyoid bone, soft palate, cervical vertebra, pharynx (nasopharynx, oropharynx and laryngopharynx). Anthropometric measurements of the width of the dental Arch By Method A. Pont, the length of The Frontal segment of the dental arch – according to the G method.Korkhaus. Research results. According to the results of the study, all anthropometric and TRH indicators were significantly worse in patients with impaired external respiratory function, especially in patients in Class II of the English subclass, which leads to a deterioration in the course of the disease and predicting the effectiveness of its treatment. Conclusions. In order to determine the effectiveness of orthodontic treatment of distal bite, it is necessary to conduct an anthropometric and cephalometric study before and after the treatment in order to determine its effectiveness.
