Endodontically treated teeth are more prone to biomechanical failures than vital teeth. As a result of these failures, the prognosis of the tooth is adversely affected and tooth loss may occur. To date, no consensus has been reached in the literature on which technique or material can best restore endodontically treated teeth. As an alternative to restorative procedures such as post and crown, which is the traditional approach for root canal filled teeth, the correct selection of the case-specific restorative technique and material has become more important with the development of adhesive technologies today. In experimental and clinical studies, deviations can be seen in the results depending on many factors such as the observer, equipment and teeth. With finite element analysis, complex structures and their biomechanical behaviors can be determined by avoiding the bias caused by these factors. In this section, studies in which different post-endodontic restorations have been evaluated using finite element analysis will be reviewed.
