После резекции верхней челюсти обтураторы также подвергаются воздействию микроорганизмов, обитающих в носу и придаточных пазухах. Цель – оценить in vitro образование биопленки различными видами бактерий полости рта на образцах из титана и полиэфирэфиркетона (ПЭЭК) экспериментальных групп. Материал и методы. Всего было приготовлено 115 образцов, которые, в зависимости от обработки, были разделены на 6 групп: 1 группа (контроль) включала 15 образцов гладкообработанного титанового сплава – T-с; 2 группа – 20 образцов титана, обработанного лазером – Т-л; 3 группа – 20 образцов гладкообработанного ПЭЭК; 4 группа – 20 образцов ПЭЭК, модифицированного лазером – ПЭЭК-л; 5 группа – 20 образцов ПЭЭК, обработанного плазмой – ПЭЭК-п; 6 группа – 20 образцов ПЭЭК, обработанного лазером и плазмой – ПЭЭК-лп. Титановые диски были отфрезерованы из титанового сплава, диски ПЭЭК готовили из стержней ПЭЭК и впоследствии подвергали лазерному текстурированию с микроканавками. Использованы эталонные штаммы Streptococcus mutans, Streptococcus oralis, Candida albicans, Staphylococcus aureus, Porphyromonas gingivalis, Fusobacterium nucleatum. Результаты. Наименьшее количество всех видов микроорганизмов наблюдалось на поверхности образцов ПЭЭК, обработанных плазмой, а также лазером и плазмой, т.е. в 5 и 6 группах. Наиболее высокие прикреплённые КОЭ были Fusobacterium nucleatum, Streptococcus mutans и Streptococcus oralis. Образцы из ПЭЭК во многих аспектах сопоставимы с титановым сплавом и в некоторых конкретных ситуациях лечения могут быть лучшим выбором, что подтвердило нулевую гипотезу. Наши наблюдения позволили получить ценную информацию о влиянии различных видов обработки поверхности на её топографию, что может послужить основой для разработки улучшенных свойств поверхности материалов. Использование ПЭЭК в качестве альтернативы металлу является превосходным. Следовательно, постоянные обтураторы верхней челюсти с фиксацией из ПЭЭК можно рассматривать как перспективный метод лечения пациентов с приобретенными дефектами верхней челюсти.</p></abstract><trans-abstract xml:lang="en"><p>t Obturator prostheses can be populated by microorganisms and function as a reservoir of infection. After resection of the upper jaw, the obturators are also exposed to microorganisms living in the nose and paranasal sinuses. The aim is to evaluate in vitro biofilm formation by various types of oral bacteria on titanium and polyesteresterketone (PEEK) samples from experimental groups. Materials and methods. A total of 115 samples were prepared, which, depending on the treatment, were divided into 6 groups: group 1 (control) included 15 samples of smoothtreated titanium alloy - T-a; group 2 – 20 samples of titanium treated with laser – T-l; group 3 – 20 samples of smooth-processed PEEK; group 4 – 20 samples of PEEK modified with a laser – PEEK-l, group 5 – 20 samples of PEEK treated with PEEK-p; group 6 – 20 samples of PEEK treated with a laser and plasma – PEEK-lp. Titanium discs were milled from titanium alloy, PEEK discs were prepared from PEEK rods and subsequently subjected to laser texturing with micro grooves. Reference strains of Streptococcus mutans, Streptococcus oralis, Candida albicans, Staphylococcus aureus, Porphyromonas gingivalis, and Fusobacterium nucleatum were used. Results. The smallest number of all types of microorganisms was observed on the surface of PEEK samples treated with plasma, as well as laser+plasma, i.e. in groups 5 and 6. The highest attached CoES were Fusobacterium nucleatum, Streptococcus mutans, and Streptococcus oralis. Samples from PEEK are comparable to titanium alloy in many aspects and may be the best choice in some specific treatment situations, which confirmed the null hypothesis. Our observations allowed us to obtain valuable information about the influence of various types of surface treatment on its topography, which can serve as a basis for the development of improved surface properties of materials. The use of PEEK as an alternative to metal is excellent. Therefore, permanent upper jaw obturator with PEEK fixation can be considered as a promising method of treating patients with acquired maxillary defects.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>протез-обтуратор</kwd><kwd>in vitro</kwd><kwd>титан</kwd><kwd>полиэфирэфиркетон</kwd><kwd>биопленка</kwd><kwd>микроорганизмы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>obturator prosthesis</kwd><kwd>in vitro</kwd><kwd>titanium</kwd><kwd>polyesteresterketone</kwd><kwd>biofilm</kwd><kwd>microorganisms</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Пустовая И.В., Енгибарян М.А., Светицкий П.В., Аединова И.В., Волкова В.Л., Чертова Н.А. и лр.
