CHARACTERISTICS OF THERMOPLASTIC POLYMER DENTURE BASE MATERIALS FOR PROSTHODONTIC CONSTRUCTIONS

Abstract

Introduction. In dentistry, there is a wide range of thermoplastic polymers for the removable constructions of dental prostheses, which are extremely promising in modern dental practice. Successful prosthetics of patients will depend on the properties of the selected structural materials.. Purpose of the study was to summarize current information, based on a review of literary sources, on the use of thermoplastic base materials for the manufacture of removable prostheses and improves the effectiveness of orthopedic treatment of patients with complete or partial absence of teeth. Methods. A literature review was conducted using PubMed, Web of Science, SCOPUS, Google Scholar up to January 2024. There was no restriction on the date of publication or language. Searches using the MeSH (Medical Subject Headings) terms were conducted using synonyms and combinations of the following search terms: "removable prosthetics", "dental base materials", "thermoplastics" "materials science", and "adaptation". Used methods: bibliographic and analytical. Results. Thermoplastic materials are characterized by bioinertness for the organism, because they do not contain residual monomer. The technology of injection molding of thermoplastic polymers is considered as a promising technology in modern dentistry to achieve high aesthetic standards. The general characteristic of this group of materials is the absence of residual monomer and, accordingly, their biological indifference, a high level of plasticity, precision during the manufacture of the prosthesis, and a wide range of colours. Conclusion. Polymer denture base plastics do not have optimal physico-mechanical, biological and surface characteristics, so the search for new materials for the manufacture of removable prostheses remains a promising direction
