STRENGTH PROPERTIES OF ELASTIC DENTAL MATERIALS ON THE BASE OF MODIFIED POLYACRYLATES

Abstract

A comparative analysis of the strength properties of hydrogel composition and implants made of polymethylmethacrylate was conducted. Based on polyvinylpyrrolidone and 2- hydroxyethyl-methacrylate including additives of hydrophobic monomers a composition for making soft lining have been proposed. The adhesion strength (tension) of elastic materials bond by the method of “shear” and “breakaway” was studied. It was determined that adhesive strength values of hydrogel composition are quite high. It makes possible applying the composition as cover layer for the removable dentures basis.
