| Popis: | The treatment process of a tooth every short period has many disadvantages to the dental patient, for instance, wasting time, losing money, and tiring the dental patient. Therefore, selecting the suitable technique for treating the tooth, with increasing the lifetime of the tooth has become more necessary in the daily life of the dental scientists. In the present days, an Endodontic Prefabricated Post (EPP) plays an important vital role in the treatment process of the tooth. Comparisons among von Mises stress, shear stress, and deformation of homogenous cases were investigated in the present work through the finite element analysis (FEA). The effect of EPP material on von Mises stress, shear stress, and deformation components occurred on the dentin in cases of Functionally Graded Endodontic Prefabricated Post (FGEPP), and EPP-homogenous was carried out. After that, the sub-problem approximation method was adopted for determining the optimum material gradient for a FGEPP. |
