Abstract:

BACKGROUND: Studies demonstrates that the analytical method of three-dimensional finite element is an important research method that analyzes the biomechanical distribution of the bone interface around implants. Accurate construction of three-dimensional finite element model that provides research support for the optimization of implant design is the basis of accurate analysis.
OBJECTIVE: To establish a three-dimensional finite element model of fixed bridge supported by implants with three kinds of different forms in the anterior maxilla, and to provide the mathematical model for biomechanical research.
METHODS: A three-dimensional finite element model of fixed bridge supported by implants with three kinds of different forms in the anterior maxilla was established by the CT scanning technology, the solid modeling technology of the Geomagic studio 9.0 software and Mimics 10.01 software, and the technology of Finite Element Analysis with the ANSYS 10.0 software.
RESULTS AND CONCLUSION: The three-dimensional finite element model which was consisted of 204 854 elements and 365 173 nodes and obtained the forms of the jaw, maxillary central incisors, lateral incisors, implant and porcelain crown-bridge was successfully constructed, which had a good geometrical similarity. The method that combining the CT scanning technology and digital image treatment technology by using a series of computer software to establish a three-dimensional finite element model is conceivable.
