The aim of this study is to investigate the dependence of its intensity on the design features of the manufactured denture. In the course of the study, 90 patients were selected and divided into 3 equal groups. Patients from group A were rehabilitated using a removable plate denture of the original design, while patients from groups B and C were rehabilitated using dentures made of thermoplastics and acrylic polymers. After prosthetics, at the time of 6, 12, 18 months of the study, patients underwent CBCT and X-ray densitometry. Based on the data obtained, after statistical processing, average indicators for the groups for each time point were calculated. According to them, it was found that in patients from group A at the time of examination on month 6, the volume of bone tissue was on average greater than 2.83 mm and 7.9 mm than in patients from groups B and C. Similarly, at the time of examination on month 12, this difference was 5.77 and 10.37 mm, and at the time of examination on month 18, 6.9 and 12.3 mm. In turn, the densitometry results in group "A" at the time of examination on month 6 were better than the indicators of groups "B" and "C" by 19 and 39 units. At the time of examination on month 12, the densitometry indicators in group "A" were better than in groups "B" and "C" - by 30 and 50 units, and at the time of examination on month 18 - by 10 and 31 units, respectively. Thus, the study found that the removable plate denture of the original design allows to reduce the severity of atrophic processes occurring in the area of the prosthetic bed.</p>dentures, partial, removableAlveolar ProcessDentistryProsthodonticsDental Care for Chronically Illзубные протезы частичные, съемныеальвеолярный отростокстоматологияпротезированиестоматологическая помощь хроническим больным.[1.
