   <abstract xml:lang="ru">
    <p>Статья посвящена актуальным вопросам повышения долговечности и функциональной надежности ортопедических конструкций с опорой на дентальные имплантаты. Авторами обосновывается значимость темы исследования, обусловленная необходимостью точного прогнозирования биомеханического поведения имплантационных систем, включая влияние типа соединения имплантата и абатмента, метода фиксации и угла наклона имплантата. &#13;
Актуальность исследования подтверждается активным внедрением методов математического моделирования, в частности метода конечных элементов (МКЭ), позволяющего анализировать распределение нагрузок и напряжений в костной ткани и компонентах протеза. Однако аспекты влияния различных конфигураций соединений (наружных, внутренних, конических) и способов фиксации (цементной, винтовой) на долгосрочную стабильность ортопедических конструкций остаются недостаточно изученными.&#13;
Авторами проведен систематический анализ отечественных и зарубежных научных публикаций из баз данных PubMed, Medline, Cochrane, eLIBRARY и CyberLeninka, посвященных математическому моделированию в ортопедической стоматологии. Использован комплекс методов, включающий сравнительный анализ, обобщение данных, оценку достоверности результатов и критический разбор клинических исследований.&#13;
Результаты исследования показали, что внутренние и конические соединения обладают большей устойчивостью к микроподвижности и концентрации напряжений по сравнению с наружными; винтовая фиксация обеспечивает лучшую стабильность при высоких нагрузках, тогда как цементная фиксация требует дополнительного изучения в долгосрочной перспективе; угол наклона имплантата существенно влияет на распределение напряжений в костной ткани.&#13;
Заключение. Несмотря на прогресс в области математического моделирования, сохраняется необходимость стандартизации методов анализа и проведения дополнительных исследований для оптимизации параметров имплантационных систем. Полученные данные могут быть использованы для повышения точности планирования ортопедического лечения и снижения риска осложнений.</p>

    <p>The article is devoted to topical issues of improving the durability and functional reliability of orthopaedic structures based on dental implants. The authors justify the significance of the research topic, which is determined by the need for accurate prediction of the biomechanical behaviour of implant systems, including the influence of the type of implant and abutment connection, the fixation method, and the angle of the implant. &#13;
The relevance of this research is confirmed by the active introduction of mathematical modelling methods, in particular the finite element method (FEM), which allows analysing the distribution of loads and stresses in bone tissue and prosthesis components. However, the aspects of the influence of various connection configurations (external, internal, conical) and fixation methods (cemented, screw) on the long-term stability of orthopaedic structures remain insufficiently studied.&#13;
The study conducted a systematic analysis of domestic and foreign scientific publications from the PubMed, Medline, Cochrane, eLIBRARY, and CyberLeninka databases devoted to mathematical modelling in orthopaedic dentistry. A set of methods was used, including comparative analysis, data summarisation, assessment of result reliability, and critical analysis of clinical studies.&#13;
The results of the study showed that internal and conical connections are more resistant to micromobility and stress concentration than external ones; screw fixation provides better stability under high loads, while cemented fixation requires further study in the long-term; the angle of the implant significantly affects the distribution of stresses in bone tissue.&#13;
Conclusion. Despite advances in mathematical modelling, there is still a need to standardise analysis methods and conduct additional studies to optimise the parameters of implant systems. The data obtained can be used to improve the accuracy of orthopaedic treatment planning and reduce the risk of complications.</p>
