| Abstract: | Objective: To explore an easier and more precise method for reconstruction of 3D finite element model of dentulous mandible. Methods: Thin-layer CT scanning was used to obtain the morphological data of subjected mandible. Matlab scientific calculation software was employed to process the data and to reconstruct the 3D finite element model of dentulous mandible. Results: A more precise and widly used 3D finite element model of dentulous mandible was reconstructed. A software based on Matlab for identification of bitmap(BMP) images and for writing the digital data into Ansys software directly was developed, which improved the efficiency of reconstructing 3D finite element model. Conclusion: The thin-layer CT scanning makes the model more precise, at the same time the software can be used by dental professionals to acquire digital date from BMP. |
| Keywords: | Mandible Three-dimensional finite element model Thin-layer CT scanning Matlab (matrix laboratory) |
