Abstract

The negative impact of the residual acrylic monomer present in dental polymethyl methacrylates (PMMA), the high cost of monomer-free thermoplastic polymers, contribute to the spread of the domestic base material of light polymerization “Nolatek” (VladMiva, Russia). However, various data on the physical and mechanical properties of the material and the methods of polymerization limit its application. The purpose and objectives of our study was to study the strength characteristics of the material “Nolatek” polymerized in various ways, followed by the study of adhesion of test strains of bacteria and fungi to it.
Materials and methods.
We have carried out bending tests on samples made of “Nolatek” material polymerized using various technologies, as well as the index of adhesion of microorganisms to “Nolatek” material.
Results.
Specimens from “Nolatek” material polymerized by hybrid technology during bending tests showed a value equal to 67.289±3.327 MPa. The adhesion index of strains — P. intermedia and C. albicnas is statistically significantly lower for samples polymerized using hybrid technology than when using light polymerization.
Conclusion.
Hybrid polymerization of the base material Nolatek is able to improve the physical, mechanical and microbiological properties of removable denture constructions.
