The best results in the prosthetic treatment of dentition defects are obtained with a combined prosthesis with attachments. It ensures minimal invasiveness of treatment, reversibility of treatment, makes it possible to compensate for large dentition defects, physiologically redistributes masticatory load between the remaining teeth and the oral mucosa, mechanically connects the remaining teeth into a single system, restores chewing and speech functions, provides a good aesthetic outcome , and has a number of other important advantages. At the same time, achieving optimal retention remains a prerequisite for long-term, comfortable use of the prosthesis. The type of retentive element is crucial for prosthesis retention. Often, the clinician faces the question of choosing one of the many attachment systems available. This article analyzes the advantages and disadvantages of known methods of fixation of arch prostheses for molars and isolated premolars in the replacement of Kennedy Class II and III dentition defects.</p></abstract><trans-abstract xml:lang="ru"><p>При решении задачи восстановления частичного отсутствия зубов и дефектов зубных рядов вариантом выбора может стать качественно изготовленный дуговой или бюгельный протез, а также комбинированный протез на замковых креплениях. Наилучшие результаты при протезировании дефектов зубных рядов даёт комбинированный протез с замковыми креплениями. Он обеспечивает минимальную инвазивность лечения, обратимость лечения, позволяет восполнять большие дефекты зубных рядов, физиологично перераспределяет жевательную нагрузку между оставшимися зубами и слизистой полости рта, механически соединяет оставшиеся зубы в единую систему, восстанавливает функции жевания и речи, имеет достойный эстетический результат и обладает рядом других важных преимуществ. При этом актуальным остаётся вопрос достижения оптимальной фиксации как обязательного условия долгосрочной комфортной эксплуатации конструкции. Тип фиксирующего элемента имеет решающее значение для удержания протеза. Часто перед врачом встаёт вопрос выбора одного из многих фиксирующих элементов. В статье проанализированы преимущества и недостатки известных способов фиксации дуговых протезов для маляров и одиночно стоящих премоляров при замещении дефектов зубных рядов II и III класса по Кеннеди.</p></trans-abstract><kwd-group xml:lang="en"><kwd>arch prosthesis</kwd><kwd>clasp prosthesis</kwd><kwd>combined prosthesis</kwd><kwd>denture fixation</kwd><kwd>Kennedy Class II dentition defect</kwd><kwd>Kennedy Class III dentition defect</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>дуговой протез</kwd><kwd>бюгельный протез</kwd><kwd>комбинированный протез</kwd><kwd>фиксация протеза</kwd><kwd>дефект зубного ряда II класса по Кеннеди</kwd><kwd>дефект зубного ряда III класса по Кеннеди</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Trezubov VN, Trezubov VV.
