При непосредственном протезировании у пациентов с пародонтитом именно ранний ортопедический этап (посадка временной конструкции) часто сопровождается ишемическим побледнением слизистой, болевым ответом и внеплановыми коррекциями из-за отсутствия количественных ориентиров допустимой компрессии. Количественный силиконовый тест с заданным коридором толщины пленки позволяет стандартизировать припасовку и повысить воспроизводимость результата.</p></sec><sec><title>Цель</title><p>Цель. Повысить качество непосредственного протезирования у пациентов с пародонтитом за счет внедрения количественного силиконового теста и адресной FDM-модификации промежуточной части.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Одноцентровое проспективно-контролируемое исследование. Для оценки субъективных и операторских исходов сформированы две независимые группы по 10 пациентов: в основной группе посадка временной конструкции выполнялась с количественным контролем компрессии мягких тканей (тонкослойный С-силикон, целевой коридор 60–150 мкм) и адресной FDM-модификацией; в контрольной – стандартная клиническая подгонка без количественных ориентиров. Отдельная выборка из 48 пациентов использовалась для зональных измерений толщины силиконовой пленки (5 зон на пациента; 240 измерений). Нормальность проверяли критерием Шапиро – Уилка; межгрупповые сравнения VAS – U-критерием Манна – Уитни; связи толщины пленки с VAS – корреляцией Спирмена.</p></sec><sec><title>Результаты</title><p>Результаты. В основной группе зафиксированы более благоприятные субъективные исходы: VAS врача – медиана 6,8 [6,6; 7,1] против 9,2 [8,9; 9,3] в контроле; VAS пациента – 7,3 [5,3; 7,9] против 8,8 [8,6; 9,0] (n = 10 в каждой группе). По совокупности зон (n = 240) медиана толщины пленки составила 80 [60; 100] мкм; среднее 84,6 ± 50,3 мкм; диапазон 20–300 мкм; доля попаданий в целевой диапазон 60–150 мкм – 67,5%. Зональный профиль показал максимальную управляемость во вестибулярной зоне (95,8% попаданий в целевой диапазон) и минимальную – в дистальной (41,7%), что указывает на необходимость прицельной коррекции именно в этой области.</p></sec><sec><title>Заключение</title><p>Заключение. Количественный контроль посадки с использованием тонкослойного силиконового теста и адресной FDM-модификации операционно реализуем, снижает субъективную травматичность и повышает воспроизводимость раннего ортопедического этапа непосредственного протезирования при пародонтите. Полученные численные допуски и зональные ориентиры могут служить формализованными конечными точками качества и основой для стандартизации протокола в клинической практике. Требуются многоцентровые рандомизированные исследования для оценки среднеи долгосрочных исходов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. During immediate prosthetic rehabilitation in patients with periodontitis, the early prosthodontic stage– specifically the placement of a provisional restoration—is frequently associated with mucosal ischemic blanching, pain, and unplanned adjustments. These complications largely result from the absence of quantitative criteria defining acceptable levels of soft tissue compression. A silicone-based fit-checking technique with a predefined film thickness range allows standardized seating of provisional restorations and enhances procedural reproducibility.</p></sec><sec><title>Objective</title><p>Objective. To improve the quality of immediate prosthetic rehabilitation in patients with periodontitis by using a silicone-based fit-checking technique with quantitative control of film thickness combined with site-specific FDM-based modification of the pontic.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A single-center prospective controlled study was conducted. Two independent groups of 10 patients each were formed to assess patientand clinician-reported outcomes. In the study group, provisional restorations were seated with quantitative assessment of soft tissue compression using a thin-layer condensation silicone fit-checking material with a predefined film thickness range of 60–150 μm, followed by site-specific FDM-based modification of the pontic. In the control group, restorations were adjusted using standard chairside fitting procedures without quantitative reference values. An additional cohort of 48 patients was included for zonal assessment of silicone film thickness (five zones per patient; 240 measurements in total). Data normality was evaluated using the Shapiro–Wilk test. Intergroup differences in VAS scores were analyzed using the Mann–Whitney U test. Associations between silicone film thickness and VAS scores were examined using Spearman’s rank correlation coefficient.</p></sec><sec><title>Results</title><p>Results. The study group demonstrated more favorable patientand clinician-reported outcomes. Median clinician VAS scores were 6.8 [6.6; 7.1] compared with 9.2 [8.9; 9.3] in the control group, while median patient VAS scores were 7.3 [5.3; 7.9] versus 8.8 [8.6; 9.0], respectively (n = 10 per group). Across all assessed zones (n = 240), the median silicone film thickness was 80 [60; 100] μm, with a mean value of 84.6 ± 50.3 μm and a range of 20–300 μm. The proportion of measurements within the predefined target range of 60–150 μm was 67.5%. Zonal analysis demonstrated the highest degree of controllability in the vestibular region (95.8% of measurements within the target range) and the lowest in the distal region (41.7%), indicating the need for targeted correction primarily in this area.</p></sec><sec><title>Conclusion</title><p>Conclusion. Quantitative control of provisional restoration seating using a thin-layer silicone-based fit-checking technique combined with targeted FDM-based modification is clinically feasible, reduces perceived soft tissue trauma, and improves the reproducibility of the early prosthodontic phase of immediate rehabilitation in patients with periodontitis. The proposed numerical thresholds and zonal reference values may serve as formalized quality endpoints and provide a foundation for protocol standardization in clinical practice. Multicenter randomized controlled trials are required to evaluate mediumand long-term outcomes.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>пародонтит</kwd><kwd>непосредственное протезирование</kwd><kwd>силиконовый тест</kwd><kwd>FDM-модификация</kwd><kwd>визуально-аналоговая шкала</kwd><kwd>компрессия мягких тканей</kwd><kwd>зональный анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>periodontitis</kwd><kwd>immediate prosthetic rehabilitation</kwd><kwd>silicone-based fit-checking technique</kwd><kwd>FDM-based modification</kwd><kwd>visual analog scale</kwd><kwd>soft tissue compression</kwd><kwd>zonal analysis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы заявляют об отсутствии внешнего финансирования при проведении исследования.
