Предмет. Рассмотрена необходимость изучения микробиоты полости рта как одной из основных причин осложнений после установки зубных имплантатов. В динамике остеоинтеграции дентальных имплантов (1, 6 и 12 месяцев) проведено исследование видового и качественного состава микробиоты периимлантатной и десневой бророзды. Цель ― изучить состав микробиоты в десневой борозде соседнего здорового зуба и периимплантатной борозде имплантата в процессе остеоинтеграции дентальных имплантов. Методология. Проведено микробиологическое исследование состава микробиоты исследуемых биотопов ― периимплантатной борозды и десневой борозды соседнего здорового зуба в процессе остеоинтеграции дентальных имплантов у 83 пациентов. Общее число бактерий выявлено методом полимеразной цепной реакции в режиме реального времени. Результаты. Через 1 месяц после установки дентальных имплантов и фиксации формирователя десны в образцах из десневой борозды зуба количество Treponema denticola было на 16,03 %, а Tannerella forsythensis ― на 5,52 % выше, чем в образцах из периимплантатной борозды. Через 6 месяцев общая бактериальная масса в периимплантатной борозде была меньше на 12,7 %. Количество Prevotella intermedia, Treponema denticola, Tannerella forsythensis и Porphyromorans gingivalis в периимплантатной борозде снизилось на 2,9, 6,1, 5,2 и 11,6 % соответственно. Спустя 12 месяцев в периимплантатной борозде имплантата и десневой борозде зуба отмечено статистически значимое снижение Porphyromorans gingivalis в 2,7 (р<0,01) и 2,6 (р<0,01) раза соответственно. Выводы. В процессе остеоинтеграции дентальных имплантов динамично, статистически значимо снижалась общая бактериальная масса (р<0,01), Porphyromorans gingivalis (р<0,01), возрастало количество Tannerella forsythensis (р<0,05). Также динамично, но незначительно, наблюдалось снижение Candida albicans. После 12 месяцев в местах имплантации наблюдалось скопление Prevotella intermedi.

Background. The necessity of studying the microbiota of the oral cavity, as one of the main causes of complications after the installation of dental implants, is considered. In the dynamics of osseointegration of dental implants (1-6-12 months), a study was made of the species and quality composition of the microbiota of peri-implant and gingival furrows. Objectives ― to study the composition of microbiota in the gingival sulcus of an adjacent healthy tooth and the peri-implant sulcus of the implant in the process of osseointegration of dental implants. Methods. A microbiological study of the composition of the microbiota of the studied biotopes — the peri-implant sulcus and gingival sulcus of an adjacent healthy tooth in the process of osseointegration of dental implants in 83 patients was carried out. The total number of bacteria was detected by real-time polymerase chain reaction. Results. 1 month after the installation of dental implants and fixation of the Treponema denticola gingival former in the samples from the gingival sulcus of the tooth was 16.03 %, and the number of Tannerella forsythensis was 5.52 % higher than in the samples from the peri-implant sulcus. After 6 months, the total bacterial mass in the peri-implant sulcus was 12.7 % less. The amounts of Prevotella intermedia, Treponema denticola, Tannerella forsythensis and Porphyromorans gingivalis in the peri-implant groove decreased by 2.9, 6.1, 5.2 and 11.6 %, respectively. After 12 months, a statistically significant decrease in Porphyromorans gingivalis was observed 2.7 times (p <0.01) and 2.6 times (p <0.01), respectively, in the peri-implant and gingival sulcus. Conclusions. In the process of osseointegration of dental implants, the total bacterial mass (p <0.01), Porphyromorans gingivalis (p <0.01) decreased dynamically, statistically significantly, the number of Tannerella forsythensis increased (p <0.05). Also dynamically, but slightly, a decrease in Candida albicans was observed. After 12 months, an accumulation of Prevotella intermediaries was observed at the implantation sites.
