Modeling the stress state of hard tissues of a tooth in the process of restoration of class I carious cavities

Abstract

To study the stress state of geometrically complex multilayered bio-mechanical system consisting of enamel, dentin and fi lling, the three-dimensional solid modeling in the SolidWorks software package and mathematical analysis with fi nite element methods in the ANSYS Workbench program were used in the research. In the mimicking, the tooth is seen as an elastically deformable body under static loading of 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 the I class carious cavity tooth occurs in the area of enamel contact with the restoration.
