INTRODUCTION: during the period of child growth airways and facial skeleton are developing in close relationship. Patients with upper dental arch narrowing and high gothic palet, tend to have narrowed nasal passages and are more vulnerable to violations of breathing during sleep - so-called obstructive sleep apnea (OSA, Obstructive Sleep Apnea), the occurrence of which is explained by a decrease of anteroposterior sizes of throat. The aim of the study was to evaluate the effect of orthodontic treatment in the period of mixed dentition on the state of the upper respiratory tract.
MATERIALS AND METHODS: there were examined 64 children (7-12 years) with class I malocclusion. Clinical examination was carried out according to the protocols of providing orthodontic care with assessment of the functional state of the maxillofacial region. Orthodontic correction had been carried with apparatus of Biobloc system. Before treatment and after its completion there had been performed morphometric analysis of dentition and assess patency of the upper airway by McNamara method.
RESULTS: prior to the beginning of orthodontic treatment in all patients had been found a significant decrease of upper and lower pharyngeal spaces 5.95±0.75mm, 8.1 8.}0.74 mm respectively (normal - 15-20mm and 11-14mm). After orthodontic treatment with Biobloc system the upper pharyngeal space increased in 2.5 times (P<0,01), lower pharyngeal space increased in 1.6 (p<0,01) times, and in average amounted to 13,3 ± 0,86 mm.
CONCLUSIONS: thus found that after orthodontic treatment with Biobloc apparatus along with the expansion of the alveolar arches of both jaws there is a significant positive effect of increasing the volume of the upper respiratory tract. Consequently, orthodontic treatment in the period of mixed dentition, stimulates the growth not only of the dental arches, but also greatly improves the development nazomaxillary complex and prevents apnea syndrome, that increases the level patient's health and life quality.
