Сужение верхней челюсти является одной из наиболее распространенных патологий в ортодонтии. Недавние исследования показывают, что  сужение всегда асимметрично и связано с изменением положения верхней челюсти вследствие микроподвижности в костях черепа. Чтобы правильно выбрать лечение,  необходимо использовать биометрические расчеты, которые направлены на выявление  асимметрии сужения, что невозможно при использовании стандартных методов. Подходящим исследованием в данных клинических случаях, на наш взгляд, является динамическая пентаграмма Кернотта.</p><p>Цель исследования – обосновать использование метода Кернотта для анализа отклонений в зубочелюстной системе.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследовании приняли участие 35 пациентов в возрасте от 8  до 12 лет, находящихся на лечении в Институте стоматологии Первого МГМУ имени И.М.  Сеченова. Для каждого пациента была изготовлена гипсовая модель и произведен ее расчет. В этом исследовании были использованы методы Пона и Коркхауза. Эти индексы использовались для оценки изменений биометрических параметров верхней челюсти. После использования стандартных методов все модели были рассчитаны по методу  Кернотта.</p></sec><sec><title>Результаты</title><p>Результаты. В результате анализа контрольных диагностических моделей сужение верхней челюсти было выявлено в 69% случаев (n = 24). После расчета с помощью пентаграммы Кернотта все модели показали асимметричное сужение. Так, 65%  исследованных моделей показали сужение различной степени тяжести справа. </p></sec><sec><title>Выводы</title><p>Выводы. Таким образом, методы биометрического расчета моделей верхней челюсти по  стандартным показателям Пона и Коркхауза нецелесообразен при лечении пациентов с  сужением верхней челюсти, так как эти методы не дают четкого представления о  симметрии сужения. Напротив, метод Кернотта позволяет обнаруживать асимметричное  сужение верхней челюсти и своевременно корректировать лечение.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. The narrowing of the maxilla is one of the most common pathologies in orthodontics. Recent studies show that the narrowing is always asymmetric which is connected to the rotation of the maxilla. To choose the treatment correctly one need a calculation that reveals the asymmetry, which is impossible with using standard indexes.</p><p>Purpose – to compare efficiency of indexes of Pont and Korkhause with the Kernott's method in patients with narrowing of the maxilla.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study involved 35 children aged from 8 to 12 years old undergoing dental treatment in the University Children's Clinical Hospital of the First Moscow State Medical University with no comorbidities. For every patient a gypsum model was prepared and after that to carry out the biometrical calculation. In this study two indexes were used: Pont's index and Korkhause's; using this standard analysis the narrowing of the maxilla was revealed. After using Pont's Index and Korkhaus analysis all the models were calculated by the method of Kernott with Kernott's dynamic pentagon.</p></sec><sec><title>Results</title><p>Results. As a result of the analysis of the control diagnostic models a narrowing of the maxilla in 69% of cases (n = 24) was revealed in all cases, the deviation of the size of the dentition was asymmetric. Thus, 65% of the surveyed models showed a narrowing on the right. This narrowing was of a different severity and averaged 15 control models.</p></sec><sec><title>Conclusions</title><p>Conclusions. This shows that for the biometrics of diagnostic models it is necessary to use methods that allow to estimate the width of the dentition rows on the left and on the right separately. To correct the asymmetric narrowing of the dentition, it is preferable to use non-classical expanding devices that act equally on the left and right sides separetly.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>сужение верхних зубных рядов</kwd><kwd>диагностика</kwd><kwd>ALF</kwd></kwd-group><kwd-group xml:lang="en"><kwd>narrowing of maxilla</kwd><kwd>diagnostic of narrowing</kwd><kwd>ALF</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">M.
