Based on a search of publications from 2021 to 2025 in <italic>PubMed</italic>, <italic>Scopus</italic>, <italic>Web of Science</italic>, <italic>CrossRef</italic>, <italic>DOAJ</italic>, <italic>Google Scholar</italic>, and <italic>eLIBRARY.RU</italic>, more than 50 records were screened. Fourteen articles were selected according to relevance, full-text availability, and clinical focus, including clinical observations, <italic>in vitro</italic> experiments, and systematic reviews.</p> <p>Studies have shown that additively manufactured polymer restorations are bio inert, corrosion resistant, and exhibit an elastic modulus comparable to dentin, thereby reducing the risk of root fractures commonly observed in metal and zirconia systems. High-precision digital modeling provides an accurate fit and reduces the extent of tooth preparation, preserving up to 25% of hard dental tissues. Optimized post-processing (ultraviolet curing in a nitrogen environment and polishing) decreases surface roughness and improves bonding. These advantages, combined with a 40%–60% reduction in laboratory time and approximately one-third lower treatment cost, support the economic feasibility of the approach. Clinical case series with five-year follow-up demonstrate restoration stability without signs of failure or decompensation and with maintained function. Limitations include the need for expensive equipment, high energy consumption, and a shortage of clinical trial data.</p> <p>The findings suggest that polymer 3D-printed post-and-core restorations are a promising alternative to conventional systems; however, their reliability requires confirmation in expanded clinical studies with follow-up beyond five years.</p></abstract><trans-abstract xml:lang="ru"><p>Настоящий обзор обобщает актуальные данные о применении полимерных штифтово-культевых вкладок, изготавливаемых методом 3D-печати, в восстановлении эндодонтически леченых зубов. На основании поиска публикаций за 2021–2025 гг. в PubMed, Scopus, Web of Science, CrossRef, DOAJ, Google Scholar и eLIBRARY.RU было проанализировано более 50 работ. По критериям актуальности, полнотекстового доступа и клинической направленности отобрано 14 статей, включающих клинические наблюдения, эксперименты <italic>in vitro</italic> и систематические обзоры.</p> <p>Исследования показали, что аддитивно напечатанные полимерные конструкции обладают биоинертностью, отсутствием коррозии и близким к дентину модулем упругости, благодаря чему снижают вероятность появления корневых трещин, характерных для металлических и циркониевых систем. Высокая точность цифрового моделирования обеспечивает плотное прилегание и позволяет сократить объём препарирования, сохранив до четверти твёрдых тканей зуба, а оптимизированная постобработка (ультрафиолетовое отверждение в азотной среде и полировка) уменьшает шероховатость поверхности и улучшает адгезию. Указанные преимущества вкупе с сокращением лабораторного времени на 40–60% и снижением стоимости лечения примерно на треть подтверждают экономическую целесообразность технологии. Клинические серии с пятилетним наблюдением демонстрируют стабильность реставраций без признаков декомпенсации и сохранение функции. К ограничениям относят необходимость использования дорогостоящего оборудования, высокое энергопотребление и дефицит данных о клинических исследованиях.</p> <p>Полученные результаты свидетельствуют о том, что полимерные 3D-вкладки являются перспективной альтернативой традиционным системам, однако их надёжность должна быть окончательно подтверждена расширенными клиническими исследованиями, охватывающими период более пяти лет.</p></trans-abstract><kwd-group xml:lang="en"><kwd>post-and-core restorations</kwd><kwd>3D-printing</kwd><kwd>CAD/CAM dentistry</kwd><kwd>polymer post-and-core restorations</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>штифтово-культевые вкладки</kwd><kwd>3D-печать</kwd><kwd>CAD/CAM-стоматология</kwd><kwd>полимерные штифтово-культевые вкладки</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Dimitrova M, Vlahova A, Kazakova R.
