Based on cone-beam computed tomography findings, participants were divided into three groups according to the extent of vertical bone resorption around dental implants: group 1 (<italic>n</italic> = 29), resorption &lt; 1/3 of implant length; group 2 (<italic>n</italic> = 32), resorption up to 1/2 of implant length; and group 3 (<italic>n</italic> = 14), resorption &gt; 2/3 of implant length. The serum concentrations of IL-6, TNF-α, and CRP were evaluated, the implant hygiene index was analyzed, and a macrohistochemical assessment of inflammation in the transgingival portion of the abutments was performed.</p> <p><bold>RESULTS:</bold><bold> </bold>Jawbone resorption and proinflammatory cytokine concentrations in group 1 were as follows: resorption 0.6 ± 0.1 mm, IL-6 concentration 0.34 ± 0.31 pg/mL, TNF-α concentration 0.5 ± 0.1 pg/mL, CRP concentration 2.6 ± 6.0 pg/mL; in group 2, resorption was 2.4 ± 0.8 mm, IL-6 concentration 1.3 ± 0.5 pg/mL, TNF-α concentration 1.7 ± 0.5 pg/mL, CRP concentration 3.45 ± 3.40 pg/mL; in group 3, resorption was 4.6 ± 1.6 mm, IL-6 concentration 2.3 ± 0.4 pg/mL, TNF-α concentration 2.3 ± 0.2 pg/mL, CRP concentration 3.0 ± 2.2 pg/mL. Comparative analysis of cone-beam computed tomography data and concentrations of IL-6 and TNF-α revealed significant intergroup differences (<italic>p</italic> &lt; 0.001). Correlation analysis of IL-6 and TNF-α concentrations demonstrated a notable association with bone resorption across the entire sample (<italic>p</italic> &lt; 0.001). Assessment of the relationship between hygiene levels in the transgingival portion of the abutment and the degree of inflammation established a moderate correlation across the entire sample (<italic>p</italic> &lt; 0.001). The relationship between IL-6 and TNF-α cytokine concentrations and the severity of inflammation was also statistically significant.</p> <p><bold>CONCLUSION:</bold><bold> </bold>The degree of bone resorption in the implant area has a direct correlational relationship with the concentrations of proinflammatory cytokines IL-6 and TNF-α. These findings may indicate the importance of assessing the concentrations of these proinflammatory cytokines to identify a risk group among patients with implants under load for five or more years, considering localized inflammation in the transgingival portion of abutments. Additionally, cytokine status can be monitored during implant planning, potentially serving as a predictive factor for forecasting the long-term stability of implants.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование. </bold>Выявление провоспалительных цитокинов при планировании стоматологического лечения может служить прогностическим критерием в случае риска ответной воспалительной реакции организма на интегрируемые имплантаты в статусе её локальных проявлений в виде неконтролируемой резорбции костной ткани.</p> <p><bold>Цель.</bold> Оценить взаимосвязь концентрации провоспалительных цитокинов — интерлейкина-6 (ИЛ-6), фактора некроза опухоли α (ФНО-α), С-реактивного белка (СРБ) — с состоянием костной ткани челюстей в области установленных дентальных имплантатов с учётом воспалительных явлений в периимплантационной области.</p> <p><bold>Методы. </bold>Проведено исследование 75 пациентов в возрасте от 27 до 72 лет. По данным конусно-лучевой компьютерной томографии и в зависимости от степени вертикальной резорбции костной ткани в области дентальных имплантатов сформированы 3 группы обследуемых: 1-я группа (<italic>n</italic> = 29) — резорбция менее 1/3 длины имплантата; 2-я группа (<italic>n</italic> = 32) — резорбция на 1/2 длины имплантата; 3-я группа (<italic>n</italic> = 14) — резорбция более 2/3 длины имплантата. Оценивали концентрацию ИЛ-6, ФНО-α, СРБ в сыворотке крови, анализировали индекс гигиены имплантатов и выполняли макрогистохимическую оценку воспаления в области трансгингивальной части абатментов.</p> <p><bold>Результаты. </bold>Показатели резорбции и концентрации провоспалительных цитокинов в 1-й группе были следующими: резорбция 0,6 ± 0,1 мм, концентрация ИЛ-6 0,34 ± 0,31 пг/мл, концентрация ФНО-α 0,5 ± 0,1 пг/мл, концентрация СРБ 2,6 ± 6,0 пг/мл; во 2-й группе резорбция составляла 2,4 ± 0,8 мм, концентрация ИЛ-6 1,3 ± 0,5 пг/мл, концентрация ФНО-α 1,7 ± 0,5 пг/мл, концентрация СРБ 3,45 ± 3,40 пг/мл; в 3-й группе резорбция составляла 4,6 ± 1,6 мм, концентрация ИЛ-6 2,3 ± 0,4 пг/мл, концентрация ФНО-α 2,3 ± 0,2 пг/мл, концентрация СРБ 3,0 ± 2,2 пг/мл. При сравнительном изучении данных конусно-лучевой компьютерной томографии, концентраций ИЛ-6 и ФНО-α выявлены существенные межгрупповые различия (<italic>p </italic>&lt; 0,001). Корреляционный анализ концентрации ИЛ-6 и ФНО-α выявил заметную связь с резорбцией костной ткани во всей выборке (<italic>p</italic> &lt; 0,001). При оценке взаимосвязи уровня гигиены в области трансгингивальной части абатмента и степени воспаления установлена умеренной тесноты корреляционная связь также во всей выборке (<italic>p</italic> &lt; 0,001), взаимосвязь концентраций цитокинов ИЛ-6, ФНО-α с выраженностью воспаления также была статистически значима.</p> <p><bold>Заключение. </bold>Степень резорбции костной ткани в области имплантатов имеет прямую корреляционную зависимость с концентрациями провоспалительных цитокинов ИЛ-6 и ФНО-α. Полученные результаты могут свидетельствовать о важности оценки концентрации этих провоспалительных цитокинов при выявлении группы риска пациентов, имеющих имплантаты под нагрузкой в течение 5 и более лет с учётом локального проявления воспаления в области трансгингивальной части абатментов. Кроме этого, цитокиновый статус можно регистрировать при планировании имплантации, что может являться предиктивным фактором прогнозирования дальнейшей стабильности имплантатов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>dental implant</kwd><kwd>proinflammatory cytokines</kwd><kwd>inflammatory markers</kwd><kwd>bone resorption</kwd><kwd>implant-supported prostheses</kwd><kwd>resorption markers</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>дентальный имплантат</kwd><kwd>провоспалительные цитокины</kwd><kwd>факторы воспаления</kwd><kwd>резорбция костной ткани</kwd><kwd>ортопедические конструкции с опорой на имплантаты</kwd><kwd>маркёры резорбции</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Tuneva NA, Bogacheva NV, Tuneva YO.
