title: [The analysis of orthodontic force for distal movement of maxillary canine].
abstract: In this study, the finite element method combining with CAD technique was used to establish the three-dimensional mathematical model of the right maxillary canine and its periodontical tissue. We imitated the different kinds of force which were used during the orthodontic treatment, and analyzed the ways of the teeth moving and the initial stress on the teeth and periodontal tissue. Results showed that is was best to exert couple M and force P simultaneously, especially when M/P = 10 approximately 13 mm, the teeth could be moved fast and wholely without pathological destruction on the periodontical tissue. The results of this study provide some theoretical and experimental basis for clinical practice.
