TRIBOLOGICAL TESTS OF NANOCOMPOSITES FOR DIRECT RESTORATION OF TEETH
Journal Title: Tribologia - Year 2018, Vol 280, Issue 4
Abstract
The development of the interphase structure of polymer nanocomposites provides them with tribological properties difficult to obtain in traditional microfiller composites and microhybrid composites. In material solutions, it is preferable to modify the parameters of the material in order to obtain properties that are as close to the hard tissues of the teeth as possible. The aim of the study is to compare the wear resistance of new light-cured nanocomposites and to analyse the surface layer and structure before and after the wear process. Recently developed modern materials were selected for the study. In nanocomposites, G-aenial, G-aenial X FLO, and Essentia, an optimal structure was found in SEM images before and after wear, as well as low resistance to sliding friction and resistance to tribological wear. All tested composites were characterized by suitable properties for clinical applications.<br/><br/>
