A 3D Finite Element Analysis of Endodontically Treated maxillary second premolar Tooth

The aim of this study is to analyze the stresses that develop by oblique and vertical forces in endodontically treated maxillary second premolars that were restored with composite resin in four method. Additionally in our study the effects of the different restorative approaches on stress formation are analyzed using three-dimensional finite element stress analysis. For restoration, the models representing standard MOD restoration, both cusp capping for one mm and 2mm, and use of woven fiber in occlusal part were prepared. The simulation results shows that in all models, oblique forces caused more stress than vertical forces. Also, all restorative approaches have very close effect on stress formation in the tooth after endodontic treatment but we can say use of woven fiber can partly reduce stresses.
