В настоящее время протезирование с опорой на дентальные имплантаты является одним из наиболее востребованных методов реабилитации пациентов с частичным или полным отсутствием зубов. Одним из важных факторов, обеспечивающих достижение эстетичного результата и профилактику развития мукозита и периимплантита, является толщина мягких тканей вокруг шейки имплантата.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование было включено 30 пациентов с частичным отсутствием зубов и недостаточной толщиной мягких тканей в области планируемой операции. 15 пациентам была проведена аугментация с использованием коллагенового матрикса (1-я группа), 15 пациентам – свободного соединительнотканного трансплантата (2-я группа). Первичной конечной точкой являлась оценка величины прироста толщины мягких тканей через 3 месяца после операции. Вторичными конечными точками являлись: оценка ширины зоны кератинизированной прикрепленной слизистой (3 месяца после операции); выраженности отека и болевого синдрома (1, 3, 5, 7 сутки, 1 месяц и 3 месяца после операции) и оценка уровня жизни (OHIP-14) (до операции, через 7 суток и через 3 месяца после операции).</p></sec><sec><title>Результаты</title><p>Результаты. Прирост толщины мягких тканей в 1-й группе составил 1,18 ± 0,11 мм, во 2-й − 1,55 ± 0,11 мм. Длительность операции в 1-й группе была на 8,4 (от 3,737 до 13,06) минут короче, чем во 2-й. Балльная оценка послеоперационного отека показала, что у пациентов 1-й группы среднее значение на 1 сутки после операции составило 2,73 ± 0,30, у пациентов 2-й группы − 1,87 ± 0,74 (р = 0,0139). Статистически значимых различий в изменении ширины кератинизированной прикрепленной слизистой, выраженности болевого синдрома и изменении качества жизни пациентов выявлено не было (p &gt; 0,05).</p></sec><sec><title>Заключение</title><p>Заключение. Применение коллагенового матрикса, как и свободного соединительнотканного трансплантата, является эффективным методом для увеличения толщины мягких тканей в области дентальных имплантатов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. Implant-supported prostheses are currently one of the most popular rehabilitation methods in partially or fully edentulous patients. Peri-implant soft tissue thickness is one of the principal determinants to achieve an aesthetic result and prevent the development of mucositis and peri-implantitis.</p></sec><sec><title>Material and methods</title><p>Material and methods. The study included 30 partially edentulous patients with a lack of soft tissue thickness in the planned surgery site. 15 patients underwent augmentation using a collagen matrix (group 1) and 15 patients – with a free connective tissue graft (group 2). The primary endpoint was the assessment of soft tissue thickness gain three months after the surgery. The secondary endpoints were the thickness assessment of keratinized attached gingiva (three months after the surgery), swelling and pain severity (on the 1st, 3rd, 5th, 7th day, 1 and 3 months after the surgery) and quality of life evaluation (OHIP-14) (before the surgery, seven days and three months after the surgery).</p></sec><sec><title>Results</title><p>Results. The soft tissues thickness gain was 1.181 ± 0.11 mm in group 1, 1.55 ± 0.11 mm – in group 2. The surgery took 8.4 minutes less (from 3.737 to 13.06) in group 1 than in group 2. The swelling assessment on the next day after surgery showed that the mean value was 2.73 ± 0.3 in group 1, 1.87 ± 0.74 – in group 2 (р = 0.0139). There were no statistically significant differences in the change in the width of the keratinized attached gingiva, pain syndrome and changes in patients' quality of life (p &gt; 0.05)</p></sec><sec><title>Conclusion</title><p>Conclusion. Collagen matrix, like a free connective tissue graft, is an effective way to increase the soft tissue thickness around dental implants.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>пластика мягких тканей</kwd><kwd>увеличение толщины мягких тканей</kwd><kwd>свободный соединительнотканный трансплантат</kwd><kwd>коллагеновый матрикс</kwd><kwd>ксеногенная матрица</kwd><kwd>периимплантные ткани</kwd><kwd>дентальная имплантация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gingival surgery</kwd><kwd>soft tissue augmentation</kwd><kwd>free connective tissue graft</kwd><kwd>collagen matrix</kwd><kwd>xenogeneic matrix</kwd><kwd>peri-implant tissue</kwd><kwd>dental implantation</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">Chackartchi T, Romanos GE, Sculean A.
