The forces of the masticatory muscles were measured strainsometrically. The following values of gnathodinamometry were taken for analysis of mathematical models of maxillofacial region: direct in central part - 21,28-28,28 kgf, in lateral parts - 37, 52-48,02 kgf; reverse - 7.26-11,16 kgf. Vectors of masticatory muscles and muscles of hyoid bone were studied mathematically.</p></abstract><trans-abstract xml:lang="ru"><p>Нами изучены биомеханические особенности переломов нижней челюсти методами математического моделирования с учетом данных прямой и обратной гнатодинамометрии. Усилия жевательных мышц измеряли тензометрически. Для анализа математических моделей челюстно-лицевой области были взяты следующие значения гнатодинамометрии: прямой в центральном отделе — 21,28—28,28 кгс, в боковых отделах — 37, 52—48,02 кгс; обратной — 7.26—11,16 кгс. Математически исследовали векторы жевательных мышц и мышц подъязычной кости.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Kazan Medical archive</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Казанский медицинский архив</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Бадзышвили, Н.
