   <abstract xml:lang="ru">
    <p>Гастроэзофагеальная рефлюксная болезнь (ГЭРБ) вызывает хроническое закисление среды рта, что создает агрессивные условия для стоматологических материалов и требует обоснованного выбора материалов для съемных пластиночных протезов. Постоянный контакт с желудочной кислотой может приводить к гидролитической деградации полимеров и коррозии металлов, сокращая срок службы конструкций. Целью работы является проведение систематического анализа современных данных о поведении материалов базисов протезов в условиях, моделирующих воздействие желудочной кислоты, формулировка на этой основе практических критериев их клинического выбора.&#13;
На основе анализа научных публикаций за последние 10 лет проведена комплексная оценка устойчивости традиционных и современных материалов, включая термополимеризуемые акрилы, CAD/CAM-материалы и металлические сплавы, к кислой среде. Исследование базировалось на ключевых параметрах: сохранении механической прочности на изгиб, стабильности шероховатости поверхности, коррозионной стойкости и биосовместимости.&#13;
Результаты анализа показывают, что традиционный полиметилметакрилат значимо теряет прочность, а его поверхность становится более шероховатой после кислотного воздействия, что способствует адгезии микроорганизмов. В то же время материалы, изготовленные с применением цифровых технологий, такие как CAD/CAM-фрезерованные пресс-полимеры, высокопрочные композиты и 3D-печатные нанокомпозиты, демонстрируют существенно более высокую стабильность микроструктуры и свойств. Среди металлов кобальт-хромовый сплав, особенно полученный методом фрезерования, обладает лучшей коррозионной стойкостью в сравнении с никель-хромовым. Перспективными альтернативами также считаются биосовместимые композиты, армированные волокном.&#13;
Таким образом, для пациентов с ГЭРБ приоритетным является выбор современных цифровых материалов и аддитивных технологий их производства, обеспечивающих высокую устойчивость к кислотной среде. Ключевыми критериями выбора являются устойчивость к HCl (pH 1,2–3,0), стабильность механических свойств и шероховатости, коррозионная стойкость и биосовместимость. Требуются дальнейшие стандартизированные экспериментальные исследования in vitro для верификации долговременной стабильности материалов в условиях, максимально приближенных к клиническим.</p>

    <p>Gastroesophageal reflux disease (GERD) causes chronic acidification of the oral environment, creating aggressive conditions for dental materials and necessitating a well-founded selection of materials for removable plate dentures. Constant contact with gastric acid can lead to hydrolytic degradation of polymers and corrosion of metals, reducing the lifespan of the prostheses. The aim of this work is to conduct a systematic analysis of modern data on the behavior of denture base materials under conditions simulating the effects of gastric acid and to formulate practical criteria for their clinical selection based on this analysis.&#13;
Based on a review of scientific publications over the past 10 years, a comprehensive assessment of the resistance of both traditional and modern materials, including heat-polymerized acrylics, CAD/CAM materials, and metal alloys, to an acidic environment was conducted. The study was based on key parameters: retention of flexural strength, stability of surface roughness, corrosion resistance, and biocompatibility.&#13;
The analysis results show that traditional polymethyl methacrylate significantly loses strength and its surface becomes rougher after acid exposure, which promotes microbial adhesion. At the same time, materials fabricated using digital technologies, such as CAD/CAM milled prepolymers, high-strength composites, and 3D-printed nanocomposites, demonstrate significantly higher stability of microstructure and properties. Among metals, cobalt-chromium alloy, especially when produced by milling, exhibits better corrosion resistance compared to nickel-chromium alloy. Biocompatible fiber-reinforced composites are also considered promising alternatives.&#13;
Thus, for patients with GERD, priority should be given to selecting modern digital materials and additive manufacturing technologies that ensure high resistance to an acidic environment. The key selection criteria are resistance to HCl (pH 1.2–3.0), stability of mechanical properties and surface roughness, corrosion resistance, and biocompatibility. Further standardized in vitro experimental studies are required to verify the long-term stability of these materials under conditions that closely mimic the clinical setting.</p>
