Abstract:

This study aims to determine how different pressures influence stress distribution in endodontically treated deciduous maxillary central incisors fixed with various post systems.As well as a control model, 3D models of a brief post in the primary right central incisor reconstructed with glass fiber, composite, and omega steel wire were examined. In 1480, the palatoincisal section of the crown model was chewed with forces of 100, 150, and 200 N. Using Von Mises' stress criteria, the data were analyzed, and the highest principal stress was used to compare the stress values.The neck of the tooth structure was revealed to have the greatest stress. The highest Von Mises tension was exhibited by glass fiber, followed by composite, Omega steel wire, and regular tooth (control). The normal tooth (control), composite, omega steel wire, and glass fiber were found to have the lowest Von Mises pressures. To increase the likelihood of the post enduring, it should be short and over-restored with an appropriate elasticity module capable of balancing the stress concentrations. Because it and the tooth were subjected to the same amount of tension, the composite post most closely resembled the structure of a healthy baby tooth. Clinically, glass fiber and composite posts are regarded as the most superior aesthetic restorations because they are less likely to fracture and distribute stress more uniformly
