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.
