Установлено, что оптимальным лабораторным животным для экспериментального моделирования раневых дефектов слизистой оболочки твердого неба является кролик. Разработана и описана методика операции моделирования раневых дефектов слизистой оболочки твердого неба. Для эксперимента в качестве моделей использовали 10 кроликов породы «Шиншила». Моделирование раневых дефектов слизистой оболочки твердого неба выполняли под общим обезболиванием путем формирования двух симметричных дефектов слизистой оболочки твердого неба на всю толщину до кости заданной геометрической формы и заданных размеров с использованием модифицированного ручного инструмента. Разработанный метод моделирования одинаковых раневых дефектов слизистой оболочки твердого неба позволяет изучать течение раневого процесса при использовании различных методов лечения в идентичных условиях на одном животном и провести объективную математическую оценку процесса заживления раневых поверхностей в сравнительном аспекте.</p></abstract><trans-abstract xml:lang="en"><p>The issue of choosing the optimal laboratory animal for modeling wound defects of the mucous membrane of the hard palate is considered. It has been established that the rabbit is the optimal laboratory animal for experimental modeling of wound defects in the mucous membrane of the hard palate. A technique for the operation of modeling wound defects of the mucous membrane of the hard palate has been developed and described. For the experiment, 10 Chinshila rabbits were used as models. Modeling of wound defects of the mucous membrane of the hard palate was performed under general anesthesia by the formation of two symmetrical defects of the mucous membrane of the hard palate for the entire thickness to the bone of a given geometric shape and specified dimensions using a modified manual instrument. The developed method for simulating the same wound defects of the mucous membrane of the hard palate makes it possible to study the course of the wound process using different methods of treatment in identical conditions on one animal and to conduct an objective mathematical assessment of the healing process of wound surfaces in a comparative aspect.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>моделирование раневых дефектов</kwd><kwd>дефекты слизистой оболочки твердого неба</kwd><kwd>лабораторные животные</kwd><kwd>экспериментальная модель</kwd></kwd-group><kwd-group xml:lang="en"><kwd>modeling of wound defects</kwd><kwd>defects of the mucous membrane of the hard palate</kwd><kwd>laboratory animals</kwd><kwd>experimental model</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">Palatal wound healing using a xenogeneic collagen matrix – histological outcomes of a randomized controlled clinical trial / D.
