Abstract

Objectives: To study the stress distributions in maxillary central incisor restored with Ni-Cr custom-made, gold custom-made, prefabricated titanium and prefabricated glass fibre dental posts subjected to oblique occlusal load at 100 N. Materials and Methods: Four three dimensional finite element models of a maxillary central incisor restored with Ni-Cr (Model I), gold custom-made (Model II), prefabricated titanium (Model III) and prefabricated glass fibre (Model IV) dental posts were constructed and oblique loading of 100 N was applied. Stress analysing at the along the centre of the post and post-surrounding structure interfaces were computed. Results: The result of this study indicates that the clinical three-dimensional image provided information about the behaviour of teeth under function in all directions. The results obtained from a finite element model on the restored system contain information about the stress distribution of each component of the restoration. The maximum von Mises stress distribution at post center was recorded with Model I (38.6 MPa), followed by Model III (22.4 MPa) and Model II (20.8 MPa) respectively; whereas the minimum amount of stress was noticed in Model IV (10.9 MPa). At post dentin interface, the highest von Mises stress distribution was noticed with Model I (29.8 MPa), followed by Model III (18.9 MPa) and Model II (18.8 MPa) respectively; whereas the smallest amount of stress was noticed in Model IV (10.16 MPa). Conclusions: Glass fibre posts generated the least amount of stress concentration at middle and apical part of the posts compared to other dental posts.
