COMPARATIVE ASSESSMENT OF HEMODYNAMIC PARAMETERS OF THE PROSTHETIC BED MUCOSA AT THE STAGES OF TREATMENT OF PATIENTS WITH REMOVABLE DENTURE STRUCTURES USING AN IMPROVED METHOD

Abstract

The purpose of the study was to improve the quality of orthopedic treatment of patients with partial defects of the dentition due to the manufacture of removable orthopedic structures according to the improved methodology and under the control of the study of hemodynamic indicators of the mucous membrane of the prosthetic bed. From the obtained results, it was found that in the subgroup of primary prosthetic patients of the control group, who were made prostheses for the upper jaw, the indicator increased with a reliability of 99.9 % already at the second stage from (10.11±0.16) p.u. to (13.9±0.43) p.u., namely by 37.5 %. As for the primary prosthetic patients of the main group, who were made prostheses for the upper jaw, 1 day after the prostheses were applied, a significant (p<0.001) increase in the microcirculation index by 31.8 % from (11.15±0.21) p. u. to (14.7±0.82) p.u. As predicted, after 1 year of using prostheses in patients, a decrease in this indicator was determined ‒ at the IV stage it was (11.38±0.41) p.u., which is reliably (р<0.01) 18.2 % less than the previous stage and reliably does not differ from the 1st stage (р˃0.05). When the same subgroup of mandibular prostheses was manufactured for patients, a significant (p<0.05) increase in the flexmotion index by 27.9 % was recorded already at the III stage, and after 1 year it reached a value of (1.42±0.09), which significantly (p<0.001) more than the primary indicator (0.93±0.07) by 52.6 %. The analysis of the intravascular resistance of primary prosthetic patients of the control group during the manufacture of removable prostheses for the upper jaw showed that at the I stage the indicator was (3.64±0.25) %, then it gradually decreased and at the IV stage it reached a mark of (3.01±0.16) %, which is significantly (p<0.05) lower by 17.3 %. So, we can safely say that the prostheses manufactured according to our improved methodology have a more favorable effect on the capillary blood circulation of the prosthetic bed during the entire period of use of the prostheses by patients. which is due to the precise distribution of chewing pressure on the tissues of the prosthetic area.
