Abstract

Finite element models were developed for an unrestored tooth and restored tooth. The tooth was considered to be in a restored state with amalgam and composite resin on glass-ionomer as the base material. For this study, an axisymmetric model of a maxillary second premolar that included an alveolar bone was used. A load of 200 N at an angle of 45o to the radial axis was applied on the occlusal margin of the tooth. The tooth was assumed isotropic, homogenous and elastic. The authors using FORTRAN 77 prepared all calculation programs. The distributions of radial axial and shear stresses were plotted with length of radial for some critical points.
