РАЗВИТИЕ лИЦЕВОГО СКЕлЕТА У ДЕТЕЙ ПОСлЕ РАННЕЙ ПОТЕРИ ВРЕМЕННЫХ РЕЗЦОВ ВЕРХНЕЙ ЧЕлЮСТИ бимбас Е. С., Шишмарева А. С., Мельникова М. А. ФГБОУ ВО «Уральский государственный медицинский университет» Минздрава России, г. Екатеринбург, Россия Аннотация Предметом изучения данной статьи явилось развитие лицевого скелета у детей 6-10 лет. Цель -выявление особенностей развития лицевого скелета после ранней потери временных резцов верхней челюсти по данным цефалометрии.Методология. Проведено ретроспективное когортное исследование с разделением всех исследуемых детей на три группы: на детей с замещением дефекта зубного ряда, детей, не получавших ортопедическую помощь при наличии показаний к ней и детей с физиологической сменой зубов. Пациентам всех групп проводилось полное клиническое обследование, все данные статистически обработаны в программе Microsoft Office Excel. В ходе исследования в каждой группе выделены три подгруппы по данным измерения угла ANB, соответствующие I, II, III скелетным классам.Результаты. В результате исследования выявлено, что во всех исследуемых группах наиболее часто у детей определялось соотношение челюстей по I классу. Соотношение челюстей по II классу в первой и третьей (контрольной) группах наблюдалось значительно чаще, чем во второй, по III классу во второй группе -чаще, чем в третьей и первой. Таким образом, после ранней потери временных резцов верхней челюсти без своевременного протезирования характерно развитие аномалий III класса, а также установлено, что у детей, использовавших профилактические протезы, после ранней потери временных резцов осевое положение постоянных резцов верхней челюсти наиболее благоприятное при различном соотношении челюстей, а диспропорции челюстей менее выражены.Выводы. Своевременное протезирование способствует более гармоничному развитию лицевого скелета. Ключевые слова: ранняя потеря резцов верхней челюсти, профилактическое протезирование, цефалометрия. develOpMent Of children`s facial sKeletOn after early lOss Of teMpOral incisOrs Of the Upper Jaw Bimbas e. S., Shishmareva A. S., Melnikova M. A.annotationThe subject of the study in the article was the development of the facial skeleton in children 6-10 years old. The purpose of this article: to reveal the features of the development of the facial skeleton after the early loss of temporary incisors by means of cephalometry. For this, a retrospective cohort study was conducted with the separation of all the children studied into three groups: a group of children with replacement of a dentition defect, a group of children who did not receive orthopedic help, in the presence of indications to it and a group of children with physiological dentition. Patients of all groups underwent a complete clinical examination, all data were statistically processed in the Microsoft Office Excel program. During the study, in each group, three subgroups were identified according to the ANB angle measurement data, corresponding to I, II, and III skeletal classes. As a result of the study, it was found that in all the study group...
Subject. Demonstration of the clinical case retention of the upper permanent incisor and the stages of treatment. The aim of the study is to present in the clinical example the consequence of premature loss of upper temporal incisors and obstruction of nasal breathing in the form of retention of the upper permanent incisor. Methodology. The article describes the clinical case of treatment of the retention of a permanent incisor of the 9 years 11 months aged patient. The article presents a combination of the main factors for the occurrence of retention of incisors, such as premature loss of upper temporal incisors and the disruption of nasal breathing. The patient underwent a complete clinical examination with additional research methods, a phased treatment plan was drawn up. Complex orthodonto-surgical treatment on bracket system with forced diagnostic extrusion of the upper permanent incisor was carried out for 20 months. The article presents the phased dynamics of orthodontic treatment. Results. The upper permanent incisor was installed in the dentition as a result of the treatment, the upper jaw widened, a favorable closure of the dentition in the vertical plane was achieved, the jaw occlusion was preserved in class II, nasal breathing was improved. Conclusion. With early loss of upper temporal incisors, mouth breathing and contraction of the upper jaw, the use of a device with a screw along the middle line and artificial teeth is necessary, timely screening study - the analysis of orthopantomograms in children is necessary from 6 years to prevent the retention of teeth (in the period of an early replacement bite), which will allow to diagnose deviations in the development of the dentoalveolar system and start treatment in time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
