The aim of the study was evaluation the effectiveness of detection methods of excessive mechanical pressure zones of the denture basis on the mucous membrane of the prosthetic bed to improve the accuracy of corrections of prosthetic structures. At the Department of Orthopedic Dentistry and Orthodontics, the Ryazan State Medical University of the Ministry of Health of Russia developed a marker prototype and a method for its use for the diagnosis of pathological and inflammatory reactions of the oral mucosa and the correction of prosthetic structures, which allows optimizing the Schiller-Pisarev test. To evaluate the effectiveness of the method, a study was conducted involving 15 patients. In group I patients, zones of excessive pressure of the basis on the prosthetic bed were identified using corrective silicone impression masses, in group II, by staining with a chemical pencil of the alleged focus of inflammation and mechanical injury on the mucous membrane, in group III, these areas were stained with the diagnostic solution «Color-Test No. 1» using the developed marker. The effectiveness of the methods was evaluated within 7 days according to the frequency of patients seeking corrections and the area of the zones of corrections, the severity of pain when using prostheses, as well as the area of inflammation of the soft tissues of the prosthetic bed. Based on the results of the analysis of the effectiveness of the methods performed, it was found that the method for detecting excessive loading of the tissues of the prosthetic bed with the basis of the prosthesis using the developed marker made it possible to accurately and locally correct the prostheses in the number of visits half as much as in groups I and II. This ensured the greatest effectiveness of this method compared to the others, which was reflected in the smallest area of baseline adjustments (7.6 ± 1.1 mm2) and mucosal inflammation (7.2 ±0.8 mm2) in group III, since in group I the data indicators were 13.2 ± 1.9 and 8.6 ± 2, and in II - 8.8 ± 1.3 and 11 ± 1.5 mm2.
