Abstract

The tensile strength of different types of removable denture base materials was evaluated using the phenomenon of acoustic emission (AE). The peculiarities of materials fracture under the action of tensile loading have been studied. Based on the energy criterion for identification of fracture types by the AE signals, the proportion of brittle fracture in each material is estimated. The influence of different materials for finishing on the surface qua-lity of base polymers is shown. According to the analysis of research results, recommen-dations for the use of new elastic polymers in dental practice are given.
