摘　　要：目的:分析上颌牙列三维方向位置于磁力扩弓后(MPE)的改变。方法:选取30例住院治疗的患者,对其行螺旋CT测量其治疗前后的三维数据,观察治疗前后上颌牙列三维位置、标志点以及角度的变化,将数据进行配对符号检验进行比较。结果:患者上颌牙列位置在治疗前后的垂直向、矢状向以及水平向上均有改变。第1前磨牙、第1磨牙均发生了整体移动及颊倾;第1前磨牙区为上颌最大扩宽位置;上颌中切牙三维位置向前、向下移动。结论:患者上颌牙列MPE前后的变化可根据螺旋CT清晰呈现,为MPE机制的进一步研究奠定基础。Objective： To discuss the changing position in three dimensions of maxillary dentition magnetic arch expansion after. Methods： Thirty patients who were in-patient cases were selected, and received three-dimensional data measured before and after treatment it its spiral CT, observed the three-dimensional position of maxillary dentition before and after treatment, and the angle of landmarks change data paired sign test for comparison. Results： Patients in the vertical position of maxillary dentition before and after treatment, sagittal and horizontal direction are changed. First premolars, first molars occurred cheek overall movement and dumping; the maxillary first premolar region is the largest widening position; three-dimensional position of the maxillary central incisor forward, the next move. Conclusion： Patients before and after the change of maxillary dentition MPE can be clearly presented in accordance with spiral CT, lay the foundation for further research MPE mechanism.
