Abstract:

BACKGROUND: A finite element model is useful in the stress analysis of the maxillary central incisor, providing evidence for selection of clinical restoration methods.
OBJECTIVE: To establish the three-dimensional finite element model of the maxillary central incisor restored with fiber post-core crown for the stress analysis.
METHODS: The three-dimensional finite element model of half damaged maxillary central incisor restored with fiber post-core crown was established by spiral CT, Mimics software and ANSYS software. The von Mises stress and maximal tensile stress were recorded.
RESULTS AND CONCLUSION: The three-dimensional finite element model of half damaged maxillary central incisor restored with fiber post-core crown was established to simulate fiber post-core crown restoration. It was similar to the clinical case. The application of spiral CT, Mimics software and ANSYS software can successfully establish the three-dimensional finite element model of tooth structure. The model is similar to clinical case, and can develop to other similar models.
