Subject. At present, diseases of the gastrointestinal tract, with a high frequency in children aged 9―14 years, are accompanied by lesions of the oral mucosa. These conditions are aggravated with orthodontic treatment. Therefore, the development of a scheme for the prevention of complications in children with gastrointestinal diseases undergoing orthodontic treatment is an urgent task of modern dentistry. Purpose ― to consider the problem of the state of the oral cavity and the cytological characteristics of the mucous membrane in children with gastrointestinal diseases, physiological occlusion and malocclusion undergoing orthodontic treatment, to investigate the dynamics of inflammatory processes of the jaw mucosa under the bases of removable orthodontic appliances. Methodology. The study involved 60 children aged 7―15 years. The cytomorphometric method was used. Results. The results of the study showed the possibility of using the cytomorphometric method for diagnosing and evaluating the effectiveness of the use of various prevention programs and medicines during orthodontic treatment. Cytomorphometry revealed significant differences in the effectiveness of the proposed prophylaxis scheme in children, contributed to the improvement of cytogram parameters and normalization of the inflammatory-destructive index, however, complete recovery of all cytomorphological parameters in patients undergoing orthodontic treatment did not occur. Conclusions. To improve the level of oral hygiene for children undergoing orthodontic treatment, it is necessary to use not only therapeutic and prophylactic toothpastes, but also an additional amount of prophylaxis. Children with gastrointestinal tract diseases and malocclusion who are undergoing orthodontic treatment are recommended to include Lizobact drugs in the periodontal disease prevention regimen, however, the use of these drugs alone is not enough to completely eliminate the inflammatory process.

Subject. Today, nanoparticles of chemical elements that make up the body are of particular interest. Such nanomaterials usually do not cause allergic reactions, they can potentially be broken down and removed from it, and, for example, drugs can be placed in the pores of these materials. At the Department of Prosthetic Dentistry of V.G. N.N. Burdenko together with Voronezh State University developed a polymer modified with nanosized silver particles, which was successfully tested on patients in the manufacture of removable plate prostheses. However, there is no data on the effect of this polymer in patients with complex jaw pathology in combination with somatic pathology, in which visible changes occur in the oral cavity. Goal ― to consider the problem of prevention of toxic-allergic reactions when using complex-jaw prostheses and devices. To study the state of the oral microbiocenosis and the cytological characteristics of the mucous membrane in patients with apparatus bases made of a polymer modified with nanoscale silver. Materials and methods. 80 people were examined and 60 patients were treated for complete absence of teeth with various degrees of atrophy according to A.I.Doynikov (1967) I, II, III, IV, V, with a uniform quantitative distribution in groups. Methodology. 80 people were examined and 60 patients were treated for complete absence of teeth with various degrees of atrophy according to A.I.Doynikov (1967) I, II, III, IV, V, with a uniform quantitative distribution in groups. Results. The dynamics of the inflammatory processes of the mucous membrane of the prosthetic bed under the bases of removable jaw devices made by the known method and with bases from modified materials was studied. A complex of personalized prevention of complications associated with the action of basic polymers has been developed. Conclusion. Obtained by analyzing the results of the study, it was possible to create, on the basis of the use of modified acrylic polymer as the material of the bases of removable prostheses and devices, a program for individual prevention of the inflammatory complications induced by them from the mucosa of the prosthetic bed, the efficiency level of which is at least 60 %. This predisposes to recommendations for the further implementation of the modified nanosilver acrylic polymer in practical dentistry.

Анализ физико-механических свойств крема для фиксации съемных зубных протезов корега в лаборатории и клинической практике Д.м.н., проф. Э.С. КаливраДжиян, д.м.н. а.в. ПоДоПригора, к.м.н. Е.Ю. КавЕрина, М.н. БоБЕшКо воронежский государственный медицинский университет имени н.н. Бурденко, воронеж, россия В статье приведены данные о результатах лабораторного исследования адгезивных свойств крема для фиксации зубных протезов корега: адгезивной прочности и времени фиксации адгезивного материала. Также приведены данные о клинической эффективности крема корега, полученные на основе оценки индекса фиксации протеза Улитовского-Леонтьева у 18 пациентов с полным отсутствием зубов через 1 и 12 мес применения полных съемных пластиночных протезов. К концу исследования показатели фиксации съемных протезов к тканям протезного ложа у всех лиц при использовании крема для фиксации зубных протезов корега оказались выше на 8-15% (в зависимости от анатомии протезного ложа), чем без его применения, то есть у пациентов, пользующихся кремом корега в течение года отмечалась хорошая адаптация съемных пластиночных протезов при физиологических атрофических изменениях тканей протезного ложа.

Kalivradzhiyan, a.v. PodoPrigora, E.yu. KavErina, M.n. BoBEShKo voronezh State Medical university named after n.n. Burdenko, voronezh, russia The paper summarizes data on laboratory and clinical assessment of Corega denture adhesive cream adhesive properties: adhesion strength and time of adhesive material fixing. Clinical assessment was based on Ulitovsky-Leontyev denture fixation index evaluated in 18 edentulous patients with full removable dentures 1 and 12 months after denture manufacturing. After one year of evaluation denture fixation in patients using Corega denture adhesive cream was 8-15% better (depending on alveolar bed anatomy) than in controls proving that Corega improves full denture adaptation to physiological atrophy of alveolar bone.Keywords: removable dentures, adhesive preparation, Corega, fixing of removable dentures. экспериментально-теоретический раздел © Коллектив авторов, 2016*e-mail: gora76@mail.ru Взаимоотношение протеза с тканями протезного ло-жа является одной из главных проблем в практике орто-педической стоматологии [3,7]. С возрастом, даже при первичном протезировании, в процессе пользования съемными пластиночными протезами у пациентов про-исходит постепенная убыль тканей протезного ложа, что ведет за собой несоответствие рельефа базиса протеза микрорельефу слизистой оболочки протезного ложа. Атрофические процессы, происходящие при этом в об-ласти альвеолярных гребней челюстей, обусловлены не-равномерным распределением жевательной нагрузки на протезное ложе, механическим сдавливанием слизистой оболочки протезного ложа базисом съемного протеза.
