Короткий опис(реферат):
In the case of existing periodontal disease, especially in the presence of accompanying gastric and duodenal ulcer (GDU), the most biocompatible structural materials of fixed dentures should be used to minimize their impact on the main disease. It is known that not only all-metal but also ceramic fused to metal dentures can initiate a number of pathological processes in the oral cavity, in particular, oxidative stress and disruption of the metabolic processes of the components of the extracellular matrix of the periodontium, which negatively affects the course of periodontitis and requires further research.
