The long-term survival of implants is influenced by various factors, one of which is the condition of the soft tissue surrounding the implant.</p> <p><bold>AIM:</bold> To evaluate the effectiveness of cross-linked collagen matrix for soft tissue augmentation in the implant area.</p> <p><bold>MATERIALS AND METHODS:</bold> Thirty-two patients with soft tissue thickness deficiency were examined. The patients were divided into two groups depending on the method of surgery. Group 1 received a cross-linked collagen matrix, whereas group 2 underwent the transplantation of a free connective tissue graft. The increase in soft tissue thickness was assessed 3 and 6 months after surgery.</p> <p><bold>RESULTS:</bold> Soft tissue thickness 3 months after surgery increased by 1.77±0.61 and 1.26±0.41 mm in groups 1 and 2, respectively (p &lt;0.001). Moreover, 6 months after surgery, soft tissue thickness increased by 1.11±0.44 and 1.43±0.81 mm compared with the initial value (p=0.012).</p> <p><bold>CONCLUSION:</bold> The use of the collagen matrix increases the soft tissue thickness in the implant area; however, the effect size is lower than that obtained by autograft transplantation.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Дентальная имплантация является эффективным методом реабилитации пациентов при отсутствии зубов. На долгосрочную выживаемость имплантатов влияют различные факторы, одним из которых является состояние окружающих мягких тканей.</p> <p><bold>Цель исследования — </bold>оценка эффективности применения поперечно-сшитого коллагенового матрикса при аугментации мягких тканей в области имплантатов.</p> <p><bold>Материалы и методы.</bold> Были обследованы 32 пациента с дефицитом толщины мягких тканей. В зависимости от метода операции пациенты были разделены на две группы: 1-я группа — применение поперечно-сшитого коллагенового матрикса; 2-я группа — пересадка свободного соединительнотканного трансплантата. Оценку прироста толщины мягких тканей проводили через 3 и 6 мес после операции.</p> <p><bold>Результаты.</bold> Через 3 мес после операции прирост толщины мягких тканей составил 1,77±0,61 мм и 1,26±0,41 мм в 1-й и 2-й группах соответственно (p &lt;0,001). Через 6 мес после операции прирост толщины мягких тканей по сравнению с первоначальным значением составил 1,11±0,44 мм и 1,43±0,81 мм (p=0,012).</p> <p><bold>Заключение.</bold> Применение коллагенового матрикса позволяет увеличить толщину мягких тканей в области имплантатов, однако размер эффекта уступает аналогичному при пересадке аутотрансплантата.</p></trans-abstract><kwd-group xml:lang="en"><kwd>soft tissue thickness increase</kwd><kwd>gingival plasty</kwd><kwd>gingival augmentation</kwd><kwd>collagen matrix</kwd><kwd>peri-implant tissues</kwd><kwd>dental implantation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>увеличение толщины мягких тканей</kwd><kwd>пластика десны</kwd><kwd>аугментация десны</kwd><kwd>коллагеновый матрикс</kwd><kwd>периимплантные ткани</kwd><kwd>дентальная имплантация</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">World Health Organization [Internet].
