摘　　要：磁性固位体是一种应用于口腔及颌面修复的新型医疗器件。本文采用有限元法对磁性固位体的磁场进行分析 ,将麦克斯韦张量法与虚位移法的计算结果与实验值进行比较 ,通过对固位体固位力地计算得到合适的固位体尺寸。在DELPHI5 .Dental magnetic attachment is a new kind of medical device for mouth and jaw's restoring. 2-D Finite element method is introduced in this paper to analyze magnetic field of the attachments. Maxwell tensor method and Visual work principle are applied to win the most appropriate size by calculating the magnetic force. The results of those two methods are compared with the experimental result. A 2-D Finite element visual software is programmed under DELPHI5.0.
