Abstract:

BACKGROUND: The research on the micro-implant anchorage with finite element analysis method is rare, while accuracy or not of the finite element model is the main factor to determine the finite element analysis results.
OBJECTIVE: To establish the three-dimensional finite element model of maxillary first premolar and to analyze the moving characteristics of maxillary first premolar under biological forces from different angles.
METHODS: The data of the maxillary first premolar was obtained by dental CT scanning, and the conversion between CT image and three-dimensional model could be achieved by Mimics software. The three-dimensional finite element model was established by using the DICOM data modeling method, in order to simulate the biomechanical experiment of loading forces on the micro-implant anchorage from different angles, and then the moving characteristics of maxillary first premolar was analyzed.
RESULTS AND CONCLUSION: The application of this method to obtain three-dimensional finite element model of maxillary first premolar was simple and accurate, and could simulate the mechanics experiment in the greatest degree. Maxillary first premolar produces compound motor trend of distal and inclined moving, distal and lingual rotating and down movement in action of micro-implant anchorage.
