Abstract—Two parameters strongly influences the mechanical behavior of endodontically treated teeth restored with posts: the design and the rigidity of the materials. The aim of the present study was to evaluate the influence of the root preparation taper and crown materials on dowel and core restored upper central incisor. In order to obtain relevant FEA results, particular attention was given to an accurate computer reconstruction of a tooth. Round canal shapes with different tapers were modeled for the dowel, to allow the design of the cast metallic dowel-and- core 3D models. All the restorations were simulated to be covered by all-ceramic and metal-ceramic crowns. A three-dimensional finite element analysis was performed. Von Mises equivalent stresses were calculated. Areas vulnerable to damage were located in the cervical parts of the restorations. Within the limitations of the present study, it was found that the crown material is important for the stress values.
