Epidemiological studies show that only 12% of people have healthy periodontal tissues, 53% have early inflammatory changes in the supporting tissues of the teeth and 23% have destructive changes. Of these, 12% of patients have moderate to severe changes. These figures also apply to patients without orthopedic dental treatment, however, the presence of dentures in the oral cavity contributes to the emergence and development of inflammatory and destructive processes in periodontal tissues due to poor oral hygiene [2]. Most periodontal diseases are inflammatory in nature. Inflammation occurs under the influence of microbial plaque products, but at the same time, the role of local trauma, including iatrogenic causes, should be noted. According to statistics, endodontic lesions are the cause of premature removal of denture crowns in 17% of cases, mechanical destruction of cermet crowns and abutment teeth occurs in 27% of cases, and aesthetic deficiency due to destructive changes in the periodontal ligament occurs in 64% [3]. To date, most non-removable dentures are made using prepared teeth as abutments without bite, which naturally leads to chronic injury and a sharp decrease in hygiene due to the preservation of food residues and dental deposits at the edges of non-removable elements (crowns, linings, etc.).
