牵引上颌埋伏尖牙移动过程的动态模拟
Simulation of dynamic course of maxillary embedded canine.
摘要
Abstract
Objective: The three dimensional finite element model of a maxillary embedded canine and its supporting tissues was established using CT method and finite element method,and simulate dynamic course of tooth movement,consequently offer reference basis for clinic traction treatment.Method:A patient with a completely bone embedded maxillary canine was cbosen,The three-dimensional finite element model of the canine and its surmunding tissues was established using CT equipment、 Mimics、Unigraphie and MSC.Mentat, and dynamic course of tooth movement was simulated.Result: I.A similar model of maxillary embedded canine periodontium and its supporting tissues was established.2.In a period of tooth movement (28 d),the embodded canine moved 0.589 mm at the first stage (0～7 d),and 0.713 mm at the seeond stage (8～21 d), and 0.276 mm at the third stage (22～28 d).Conclusion: l.The FEM models of maxillary embedded canine established by CT、 Mimics、UG and MSC have good degrees of accuracy and geometry similarity that can meet the needs of simulation loading.2.The graph of tooth movement in a period (28 d) can represent the movement trend of embedded tooth.关键词
