Abstract:
Aim: To assess stress, and strain dissemination characteristics in root canal treated maxillary central incisors restored with two distinct dowel and core materials. Methodology: Five three-dimensional simulations of the central incisor in the maxilla were created with ANSYS (Canonsburg, PA) version 10. MODEL 1 represented a normal morphologic simulation of the incisor. MODEL 2 depicted the incisor with a pre-fabricated fiber-reinforced dowel with a glass ionomer core. The incisor of MODEL 3 consisted of the same pre-fabricated fiber post and composite core. MODEL 4 and MODEL 5 had pre-fabricated light-transmitting posts with a glass ionomer and a composite core, respectively. Each of these simulations was loaded in horizontal, vertical, and oblique directions with a load of 10N, 100N, and 50N, respectively. The resulting Von Mises stress and strain were determined. Results: Maximum stresses and strains were focused at the apex of the glass fiber reinforced post and were minimal in the middle section of the post, whereas maximum stresses and strains were mainly concentrated in the coronal region and were minimal in the middle portion of light-transmitting post. Conclusion: Pre-fabricated optical-transmitting dowel and composite core enhanced dentin stress and strain dispersion throughout various loading parameters.
