| Abstract: | A three dimensional finite element model of the maxillary canine was developed including periodontal ligament, pulp and alveolar bone. And the stress distributions in the periodontal tissue were obtained under different orthodontic force. The specific aims were to make the model by means of the more advanced and accurate twin CT,to provide more accurate data for clinical use, and to build a more accurate model for the simulation of maxillary canine movement under orthodontic forces. |
