3D fnite element analysis of stress distribution as a result of oblique and horizontal forces after regenerative endodontic treatment part II: comparison of material thickness

Beril DEMİRCAN | Pınar DEMİR

Abstract Aim This study aimed to evaluate the stress distribution caused by secondary trauma forces after regenerative endodontic treatment (RET) using diferent thicknesses of coronary barrier material with three-dimensional fnite element analysis(FEA). Method A control model was created using the tomography image of the immature maxillary central tooth with computer software.Study models were created with the modulus of elasticity and Poisson’s ratio of the materials used in RET.Enamel, dentin, cementum, periodontal ligament, cortical, and cancellous bone were modeled. Coronary barrier mate ...Daha fazlası
