The features of patient adaptation to removable partial dentures based on the dynamic study of the mucous membrane condition of an oral cavity in the new functioning conditions

Abstract

Relevance. Theadaptation to removable partial dentures is a multilevel process. At the beginning of usage, removable dentures irritate the tissues that interact directly with the prosthesis and are perceived as a foreign object by the patient. The irritating effect of prostheses is caused by their non-physiological pressure on the tissues that interact directly with the prosthesis, elimination of the bases plastic monomer, and change of the microbiological status of the oral cavity.
The goal of the study. To determine the features of clinical and functional adaptation of patients in orthopedic rehabilitation with thermoplastic and acrylic prostheses.
Materials and methods. For this clinical study, 60 patients with partial absence of teeth were examined. The patients underwent orthopedic rehabilitation with partial removable dentures (1st group — 30 patients used thermoplastic removable dentures; 2nd group — 30 patients used acrylic removable dentures).The number of patient visits for each of the studied groups for the correction in the adaptation period to fix partial removable dentures with bases of thermoplastic and acrylic materials treated with polishing pastes Blue Shine, ThermoGloss was analyzed.
Results. Clinical studies have shown clear advantages of thermoplastic prostheses. The obtained data indicate a much smaller negative impact on the removable denture bases made of thermoplastic polymer compared to the acrylic polymer bases. Also, thermoplastic dentures show better results in patient adaptation. Patients with removable dentures made of thermoplastic and acrylic polymers showed better clinical results if the surface of the dentures was treated with ThermoGloss polishing paste.
Conclusions. Using the ThermoGloss polishing paste for the final polishing of polymers has reduced the inflammatory response of the mucous membrane of the tissues that interact directly with the prosthesis and has increased its resistance to the negative effects of the partial removable dentures during adaptation. In turn, this helped reduce the number of visits to correct the prosthesis, as well as reduce the time of adaptation.
