Three-dimensional Reconstruction Of Mandible In Wild Camels And Their Force Stress Distribution Of Three-dimensional Finite Element Analysis

In this paper, five mandibles of wild camels were selected and scanned with spiral CT. Then, we did the three-dimensional reconstruction of the mandible and acquired its3D point cloud using software Amira3.1.1. By the Geomagic software, we could make a three-dimensional point cloud become solid model which could be saved as file, which can be opened in the finite element analysis software. And in the finite element analysis software Ansys14.0, we applied the force of1,000N on the mandibular angle, and acquired following results. When the force was applied on the right side of mandibular angle in90°angle, the side of mandibular angle and condylar neck were easily fractured. The inside surface of central symphysis and the right of mental foramen of mandible may show fissures, while the other was slightly damaged. When the force was applied on the left side of inferior border of mandibular. angle in90°angle, we could acquire simple result. It is revealed that, while forces were applied on the mandibular angle, Von Mises stress mainly concentrated on the weak parts of mandible, which provides theoretical basis for preliminary clinical diagnosis and treatment of mandibular fractures. It was useful to much in-depth understanding of the wild Bactrian camel mandible, and provided a basis for the subsequent three-dimensional reconstruction applications in the field.
