Smeyanov // Life and health of th eperson through the prism of the developmen tof medicine, food safety policy and preservation of the biodiversity : Peer-reviewed materials digest (collective monograph) published following the results of the CVI International Research and Practice Conference (London, August 26 - August 31, 2015). - London : Publishedby IASHE, 2015. - Р. 42-43.
Abstract To study the stress state of geometrically complex multilayer bio-mechanical system consisting of enamel, dentin and fi lling, the three-dimensional solid modeling on software package SolidWorks and mathematical analysis with fi nite element methods on program ANSYS Workbench were used in the research. In the mimicking, the tooth is seen as an elastically deformable body under static loading evenly distributed force. It is found that the inner stress in the hard tissue of intact tooth is maximum (74.2 MPa) in the area of application of the load. The maximum stress (119 MPa) in a restored over carious cavity of the I class tooth occurs in the area of enamel contact with the restoration.
