[ effect of dimension and geometrical shape of prefabricated post and the material of crown on the stress levels and distributions in the root of restored molar tooth using finite element method]

ABSTRACT

Statement of Problem: Researchers are often looking for appropriate treatments while considering esthetic aspects and health. In endodontically treated teeth afflicted with severe damage or complete loss of the coronal structure, a post is usually inserted in the root canal to provide intra-canal retention of the restorations. Therefore, it seems that it is necessary to investigate the stress distribution in the restored teeth with different post algorithms
