Results of Clinical and Hygienic Studies of Fixed Dentures in the Oral Cavity

In the modern world, the loss of one or more teeth as a result of dental diseases is one of the serious problems of the healthcare system, since it leads to a decrease in the quality of life of the patient, which leads to various diseases. According to an epidemiological study by the World Health Organization (WHO), partial or complete absence of teeth due to injuries, caries and periodontitis is observed in 75% of the population in different regions of the world [1.3.5.7.9]. According to some authors, the proportion of complete occlusive defects increases with age. Often, in the absence of one or more teeth, treatment is carried out with conventional portable prostheses or bridge prostheses with a base in the formed teeth. The need for orthopedic treatment remains high: from 30.3% in the age group of 20-29 years to 68.1% in the age group of 50-59 years. In turn, the high frequency of patients with dentition defects requires the speedy solution of such social, physiological, aesthetic and psychological problem
