| Abstract | ||||
| Aim: The aim of this study was to evaluate the stress distribution pattern and total deformation of an endodontically treated molars with large pulp chambers, restored using a composite resin core with a fiber post (FC Group) and composite resin core with novel zirconia tube (ZT Group) Materials and methods: Finite element analysis was used to simulate occlusal loading on two groups. The models in each group, were subjected to axial load of 200 N. The Von Mises stress values, distributions, and deformations were compared after the analysis. The color scale was utilized to make comparisons between the models that were studied. All deformations were calculated in mm and stress levels were calculated in Mpa. Results: Result shows that maximum tooth deformation are monitored on the Fiber reinforced composite post group -FC (0.00183mm) compared to the Composite resin core with zirconia tube-ZC (0.00154mm) which has lesser deformation. The von mises stress was higher in FC group (9.75000 Mpa) and lower in ZT group (8.85000 Mpa). When strains were examined, the strain values were less for the ZT group than for the FC group. The ZT group shows a slightly higher stress value than the FC group. Conclusion: The endodontically treated tooth with zirconia tube (ZT) showed less tooth deformation and better stress distribution than the fiber-reinforced composite post (FC). | ||||
