The presented paper is focused on the stress – strain analysis of the restored tooth. From the reason of general geometry, complex material properties and boundary conditions a computational modeling was chosen. For this problem finite element method (FEM) was used. Solved system is focused on the first lower molar where dental caries is modeled and on its subsequent treatment with restoration. The tooth, which is modeled from the dentin and enamel, is established in the segment of the mandible. The tooth with cavity class I. (according to Black) is modeled in this work. The size of dental cavity is considered in three sizes, depending on the range of dental caries. For restoration of tooth, filling materials were used. These materials are commonly used in dental practice. Force was prescribed at the occlusal surface of tooth. The model of physiological tooth was created for comparison of stress - strain states on the restored tooth. The analysis of the results shows that amalgam is the best material for tooth restoration in molar segment.
