The clinical features, the principles of differential diagnosis, development of the concept of the pathogenesis of changes in the oral cavity using ceramic-metal dentures were determined. The degree of impact of dentures on the tissues of the oral cavity depends on the quality of their manufacture, physical-chemical properties of structural materials. Recently, there has been a tendency to increase the number of patients suffering from intolerance to metal inclusions located in the oral cavity (removable and non-removable dentures). In connection with the development and implementation in practice of a large number of new structural materials, which often have not passed full-fledged laboratory and clinical trials, as well as with the significant prevalence of immunodeficiency conditions among the population, the issues of biological tolerance of materials and prevention of possible electro-galvanic complications are especially important [5]. Thus, the prophylaxis of stomatitis and paresthesias before orthopedic treatment should consist in expanding a comprehensive examination of patients in the following areas: conducting microbiological studies and bio-potentialometry, monitoring oral hygiene, studying somatic status. Measurements of the pH of the patient's oral fluid were performed thrice, the readings of the device were recorded in the examination map. The accuracy of pH determination was established using preliminary testing of the device using standard solutions and litmus paper. Most (66.7%) patients had no visible pathological manifestations in the mouth, only 33.3% showed inflammation of the mucous membrane in the form of hyperemia and edema of the mucous membrane of the mouth, lips, tongue, gingival hyperplasia.
