Модель создана на основе томографических снимков с учетом предыдущих исследований зубочелюстного аппарата человека на упрощенной модели для трех моляров. Целью работы является определение с помощью трехмерного компьютерного конечно-элементного моделирования напряженно-деформированных состояний системы «челюсть – периодонт – зуб – дентин» для различного количества резцов и их расположения. Результаты исследования позволяют получить более полную и точную оценку состояния зубочелюстного аппарата человека в целом и каждого его элемента в отдельности с целью совершенствования технологий и методов протезирования.</p></abstract><trans-abstract xml:lang="en"><p>Complex interaction of incisors of the multi-element system “jaw – tooth – periodontium – enamel – dentinˮ is considered in the present work. The model was created on the basis of tomographic images taking into account previous studies of the human dental apparatus for a simplified model of three molars. The aim of the work is to determine the stress-strain states of the “jaw – periodontium – tooth – dentinˮ system for a different number of incisors and their location using three-dimensional computer finite-element modeling. The results of the study allow obtaining a more complete and accurate assessment of the state of the human dentofacial apparatus as a whole and each of its elements separately in order to improve the technologies and methods of prosthetics.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>трехмерное моделирование</kwd><kwd>биомеханика</kwd><kwd>биоинформатика</kwd><kwd>напряженнодеформированное состояние</kwd><kwd>зубочелюстной аппарат человека</kwd><kwd>челюсть</kwd><kwd>зубы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>three-dimensional modeling</kwd><kwd>biomechanics</kwd><kwd>bioinformatics</kwd><kwd>stress-strain state</kwd><kwd>human dental apparatus</kwd><kwd>jaws</kwd><kwd>teeth</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">Щербаков С.С., Коваль И.В.
