However, the relationship between the configuration of the augmented space, subsequent bone remodeling, and long-term clinical outcomes has not been described in sufficient detail.</p> <p><bold>AIM:</bold> To assess the association between cone-beam computed tomography (CBCT)-based configuration of the augmented subantral space, augmented bone stability, and dental implant survival after sinus floor elevation.</p> <p><bold>METHODS:</bold> This retrospective observational case-series study included 193 consecutively operated patients. According to postoperative CBCT morphology, five configurations of the augmented subantral space were identified: dome-shaped elevation, sinus recess filling, uniform Schneiderian membrane elevation, transcrestal (closed) sinus lifting with a mound-shaped contour, and island-like configuration. Follow-up CBCT was performed at 6 months, 1 year, 3 years, and ≥5 years. Implant survival, augmented bone height changes, and inflammatory sinus-related complications were assessed. The statistical analysis was descriptive.</p> <p><bold>RESULTS</bold><bold>:</bold> Over ≥5 years, the highest frequency of successful outcomes was observed with recess filling (100%) and uniform elevation (approximately 99%), slightly lower with dome-shaped elevation (approximately 83%) and mound-shaped configuration (approximately 62%), and the lowest with island deposits (approximately 33%). Uniform distribution of the graft and targeted correction of recesses were associated with minimal resorption, absence of significant inflammatory complications, and implant survival of 98%–100% at the five-year mark.</p> <p><bold>CONCLUSION:</bold> In this retrospective case series, the configuration of the augmented subantral space was associated with bone remodeling and implant stability after sinus floor elevation. The most favorable outcome profiles were observed for uniform Schneiderian membrane elevation and sinus recess filling, whereas island-like configuration was more often associated with unfavorable remodeling. These findings should be interpreted as exploratory clinical trends requiring prospective validation.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Субантральная аугментация широко применяется при дефиците костной ткани в дистальных отделах верхней челюсти. Однако связь между конфигурацией сформированного аугментированного пространства, последующим ремоделированием кости и отдалёнными клиническими исходами описана недостаточно подробно.</p> <p><bold>Цель.</bold> Оценить связь между конфигурацией аугментированного субантрального пространства по данным конусно-лучевой компьютерной томографии (КЛКТ), стабильностью аугментированной кости и выживаемостью дентальных имплантатов в отдалённые сроки после синус-лифтинга.</p> <p><bold>Методы.</bold> Выполнено ретроспективное одноцентровое/многобазовое наблюдательное исследование типа серии случаев на материале 193 последовательно оперированных пациентов. По данным послеоперационной КЛКТ случаи распределяли на пять вариантов конфигурации аугментированного пространства: куполообразное поднятие дна пазухи, заполнение бухты верхнечелюстного синуса, равномерное поднятие мембраны Шнайдера, трансальвеолярный (закрытый) синус-лифтинг с бугоркообразным контуром, островковая конфигурация. Контрольную КЛКТ выполняли через 6 мес, 1 год, 3 года и 5 лет и более. Оценивали сохранность имплантатов, изменение высоты аугментированной кости и наличие воспалительных осложнений со стороны верхнечелюстной пазухи. Статистический анализ носил описательный характер.</p> <p><bold>Результаты.</bold> На горизонте ≥5 лет наибольшая частота успешных исходов зарегистрирована при заполнении бухты (100%) и равномерном поднятии мембраны Шнайдера (около 99%), несколько ниже — при куполообразном поднятии (около 83%) и бугоркообразной конфигурации (около 62%), минимальные показатели отмечены при островковых депо (около 33%). Равномерное распределение аугментата и направленная коррекция бухт ассоциировались с минимальной резорбцией, отсутствием значимых воспалительных осложнений и выживаемостью имплантатов 98–100% на пятилетнем сроке.</p> <p><bold>Заключение.</bold> В данном ретроспективном исследовании конфигурация аугментированного субантрального пространства ассоциировалась с характером ремоделирования кости и клинической стабильностью имплантатов после синус-лифтинга. Наиболее благоприятные профили исходов наблюдались при равномерном поднятии мембраны Шнайдера и заполнении бухты, тогда как островковая конфигурация чаще сочеталась с неблагоприятным ремоделированием. Полученные данные следует рассматривать как клинические тенденции, требующие подтверждения в проспективных исследованиях.</p></trans-abstract><kwd-group xml:lang="en"><kwd>subantral augmentation</kwd><kwd>sinus lifting</kwd><kwd>osseointegrated implants</kwd><kwd>reparative osteogenesis</kwd><kwd>cone-beam computed tomography</kwd><kwd>biomaterials for regeneration</kwd><kwd>peri-implant outcomes</kwd><kwd>bone matrix resorption</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>субантральная аугментация</kwd><kwd>синус-лифтинг</kwd><kwd>остеоинтегрированные имплантаты</kwd><kwd>репаративный остеогенез</kwd><kwd>конусно-лучевая компьютерная томография</kwd><kwd>биоматериалы для регенерации</kwd><kwd>периимплантатные исходы</kwd><kwd>резорбция костной матрицы</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Maksyukov SYu, Boyko NV, Pilipenko KD, et al.
