Резюме. Зміни у фагоцитарній активності лейкоцитів при бактеріально-імунному пародонтиті можуть бути важливим показником прогресування захворювання і впливу ортопедичних конструкцій на імунну реакцію організму використанні протезних базисів. Мета дослідження – з’ясувати патогенетичну роль неспецифічної ланки реактивності експериментальному та за умови використання різних типів знімних конструкцій. Матеріали методи. Експерименти було проведено білих щурах. Зубні протези виготовляли стандартними методами: акрилові базиси шляхом термічної полімеризації з поліметакрилатного матеріалу, а нейлонові термопластичного матеріалу методом пресування під тиском. Експериментальний бактеріально-імунний пародонтит дослідних тварин індуковано ін’єкційного введення суміші мікроорганізмів, суспендованих яєчному білку в тканини пародонта. Кров для отримували механічно ушкоджених судин ділянці запалення. Мазки готували фарбували Ціля Нільсена. Результати виражали вигляді фагоцитарного числа індексу. досліджень їх обговорення. На 30-ту добу запального процесу пародонтальному комплексі фагоцитарна активність зросла. Під час індексу використанням акрилових базисів виявлено його підвищення, порівняно контрольними тваринами, цей індекс також був більшим, групою щурів, які мали без протезування. При нейлоновими конструкціями фагоцитарний гранулоцитів перевищував показник контрольній групі. Зазначений вищим, ніж показники протезування акриловими протезними базисами. Фагоцитарне число умов протезів збільшилось, показниками контролю групи протезування, й отримані результати були вищими. застосуванні нейлонової пластмаси даний значно рівень показника контрольної виявився вищим від показників, що щурів Порівняно даними, отриманими групі іншим типом базисної акрилом, фагоцитарне підвищене. Висновки. розвитку модельованого відзначалося підвищення фагоцитарної крові. Використання сприяло збільшенню значень В базисами рівня із запаленням протезами.
