Abstract
Relevance. Currently, the technologies and materials used in orthopedic dentistry are constantly being improved. Nevertheless, the frequency of complications after prosthetics, unfortunately, is still quite high. The presence of orthopedic structures in the oral cavity contributes to the development of dysbiosis and the occurrence of pathological processes on the mucous membrane of the tongue, cheeks, lips in the form of long-term non-healing erosions, hyperplasia and hyperkeratosis, the appearance of unpleasant subjective sensations in the form of burning, tingling and anemia. A long-lasting inflammatory process in the oral cavity is the result of the action of pathogenic microflora and its activation in the presence of dentures. The presence of dysbiosis plays an essential role in the pathogenesis of chronic diseases and is one of the most significant causes of the appearance of destructive and non-destructive forms of damage to tissues and organs of the oral cavity [2.4.6.8.10].
