Проведение гистоморфометрического анализа мягких тканей, полученных в результате применения коллагенового матрикса и соединительнотканного трансплантата. В рамках исследования было проведено обследование и лечение 30 пациентов, которых случайным образом распределили на две группы. В 1-й группе для увеличения толщины мягких тканей применяли свободный соединительнотканный трансплантат (ССТ) с неба или бугра верхней челюсти, во 2-й группе использовали коллагеновый матрикс с поперечно-сшитой структурой (КМ). Через 3&amp;nbsp;месяца после оперативного вмешательства на этапе установки формирователей десны при помощи мукотома проводили забор фрагмента мягких тканей для проведения гистоморфометрического анализа. В обеих группах слизистая оболочка биоптатов десны была выстлана многослойным плоским эпителием относительно большой толщины с выраженным акантозом. Собственно слизистая оболочка десны, отграниченная от эпителия базальной мембраной, представлена рыхлой соединительной тканью. По итогам морфометрического анализа статистически значимых различий выявлено не было, за исключением того, что среднее значение количества клеток воспаления в эпителиальном слое в группе ССТ было равно 7,1 &amp;plusmn; 0,8, при этом в группе КМ &amp;ndash; 12,8 &amp;plusmn; 1,1 (p = 0,0001), в собственно слизистой оболочке этот показатель в группе ССТ был равен 63,8 &amp;plusmn; 4,9, а в группе КМ &amp;ndash; 82,7 &amp;plusmn; 9,0 (p = 0,03). Доля коллагеновых волокон в группе ССТ достигала 88,5 &amp;plusmn; 0,9&amp;nbsp;%, а в группе КМ &amp;ndash; 82,5 &amp;plusmn; 1,8&amp;nbsp;% (0,005). После проведенного гистоморфометрического анализа можно сделать вывод о возможности применения коллагенового матрикса в качестве материала для увеличения толщины мягких тканей.</p></abstract><trans-abstract xml:lang="en"><p>Enhancing the effectiveness of treatment for patients with soft tissue deficiency during dental implant placement in esthetically important areas is a relevant issue in surgical dentistry. To conduct a histomorphometric analysis of soft tissues obtained using a collagen matrix and connective tissue graft. The study included 30 patients who were randomly assigned to two groups. In the first group, a free connective tissue graft from the palate or the tuberosity of the maxilla was used to increase the thickness of soft tissues, while in the second group, a cross-linked collagen matrix was used. Three months after the surgical intervention, a soft tissue biopsy was taken using a mucotome during the placement of gingival formers in the area where tissue thickness had been increased. Results. The biopsy specimens from both groups showed a multi-layered squamous epithelium of relatively large thickness with pronounced acanthosis. The lamina propria of the biopsy specimens, delimited from the epithelium by the basal membrane, was represented by loose connective tissue. The morphometric analysis did not reveal any significant differences between the groups, except for the average value of the number of inflammatory cells in the epithelial layer in the CTG group was equal to 7.1 &amp;plusmn; 0.8, while in the CM group &amp;ndash; 12.8 &amp;plusmn; 1.1 (p = 0.0001), in lamina propria this indicator in the CTG group was equal to 63.8 &amp;plusmn; 4.9, and in the CM group &amp;ndash; 82.7 &amp;plusmn; 9.0 (p = 0.03). The proportion of collagen fibers in the CTG group reached 88.5 = 0.9 %, and in the CM group 82.5 = 1.8 % (0.005). Based on the histomorphometric analysis, it can be concluded that a collagen matrix can be used as a material for increasing the thickness of soft tissues.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>соединительнотканный трансплантат</kwd><kwd>ксеногенный коллагеновый матрикс</kwd><kwd>увеличение объема мягких тканей</kwd><kwd>дентальный имплантат</kwd><kwd>гистоморфометрический анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>connective tissue graft</kwd><kwd>xenogenic collagen matrix</kwd><kwd>soft tissue volume increase</kwd><kwd>dental implant</kwd><kwd>histomorphometric analysis</kwd></kwd-group></article-meta></front><back><ref-list><title>Список литературы</title><ref id="B1"><mixed-citation>Ашурко И.П. и др. 2022.
