ANALYSIS OF THE ADVISABILITY OF USING DIFFERENT TYPES OF BASE PLASTICS BY STUDYING THE NEEDS OF THE POPULATION IN REMOVABLE PROSTHESIS

Abstract

The aim: To determine the needs of the population of the Ternopil region in prosthetics with removable orthopedic dentures and to study the physical and technological properties of different types of base plastics. Materials and methods: The needs of Ternopil and Ternopil region population in removable prosthetics were studied on the basis of consolidated annual reports of city and district dental clinics of Ternopil region. Base dental plastics «Ftoraks» (Stoma, Ukraine) and «Villacryl H Plus» (Zermapol, Poland) were used to study the physical and mechanical properties (deformations during compression and tension). Results: As a result of our research, we found that the need of the Ternopil region population for removable prosthetics is quite high. When analyzing the choice of designs of removable laminar prostheses, it was found that 64.99 ± 0.14% of patients required the manufacture of partial removable dentures, and 35.01 ± 0.18% – complete removable dentures. A significant difference was found in the physical and technical characteristics of the samples of the studied plastics, which were polymerized by various methods. Conclusions: Dental base plastic «Villacryl H Plus», which was packaged and polymerized by casting, has significantly higher physical and mechanical properties than dental base plastic «Ftoraks».
