WAYS OF IMPROVING THE QUALITY OF PROSTHETICS OF MILITARY PERSONNEL.

OBJECTIVE: The aim: Justify the choice of the construction material of dental prostheses, taking into account the clinical picture and concomitant diseases in military personnel and the study of the dynamics of military personnel seeking orthopedic dental care. PATIENTS AND METHODS: Materials and methods: 185 military personnel were examined and fitted with prosthetics in the period from March 2022 to March 2023. Methods: general clinical, content analysis, bibliosemantic, medical and statistical. RESULTS: Results: All patients who came to us for dental care had previously been replaced with fixed metal structures. Of them, 121 people indicated problems related to the use of metal prostheses. From these patients, a risk group of intolerance to prosthesis materials was formed and a search was made for base materials that would be biologically indifferent. For the manufacture of partial removable prostheses, we chose the basic thermoplastic material Acron, manufactured by Roko (Poland), which has high biocompatibility with the tissues of the prosthetic bed. When choosing the structures of partial removable prostheses in patients with various defects of the dentition, we were guided by a small number of clinical visits, which is relevant for military personnel who are on rotation and treated in the hospital. CONCLUSION: Conclusions: Our careful selection of structural material made it possible to prevent complications and produce high-quality removable prostheses in a short period of time. An analysis of the reasons for orthopedic care showed low awareness of the servicemen regarding the need for timely orthopedic treatment.

THE EFFECT OF MONOMER OF REMOVABLE DENTURE BASE RESIN ON THE STRUCTURAL ORGANIZATION OF THE GLANDULAR ZONE OF ALBINO RAT HARD PALATE IN THE EXPERIMENT.

OBJECTIVE: The aim: The paper presents the findings of the study of the 3 month-long effect of the monomer of the "Ftorax" denture base acrylic resin on the structural organization of the mucous membrane and the condition of the salivary glands of the albino rats' hard palate during the experiment. PATIENTS AND METHODS: Materials and methods:To achieve this goal, experimental studies involved mature rats, whose hard palate mucosa was smeared with 2% aqueous solution of the monomer of the "Ftorax" denture base acrylic resin twice a day in the morning and evening. The animals were sacrificed on day 30 of the experiment and following 3 months. RESULTS: Results: The findings of the studies of the structural organization of the mucous membrane and the analysis of the micropreparations of the mucous membrane of the hard palate of the animals of Group III have revealed substantial pathological changes both in the covering epithelium and in the lamina propria. The comparison between the intact animals and group of animals subjected to the 3 month-long effect of the monomer showed a significant thickening of the epithelial layer; a decrease in the mitotic index in the basal layer; impaired stratification of the cellular elements of the spinous layer; manifestations of exudative purulent inflammation, cystic and sclerotic changes in the excretory ducts; increase in the amount of connective tissue in the lobules of the salivary glands; decrease in the volume of the secretory parenchyma. CONCLUSION: Conclusions: Based on the findings of the study we can conclude that the prolonged effect of the monomer of the denture base acrylic resins leads to disorder of the structural organization of the glandular zone of the hard palate; in its submucous layer the total volume of the salivary glands decreases, which, in turn, significantly reduces secretion and leads to hyposalivation.
