Objective: To study the tooth size correlation between permanent cuspid and bicuspid group and other teeth groups in malocclusion.
目的：研究错牙合、正常牙合的尖牙、双尖牙组与其它组牙的相关性，为尖牙、双尖牙组的预测提供科学依据。
Conclusion: Predicting the tooth size of cuspid and bicuspid group in malocclusion can't simply follow the law of normal occlusion.
结论：临床上对错尖牙、双尖牙组的预测不能简单等同于正常。
Methods: a 3-d FEM model of lower cuspid was established by using DICOMdata and stimulant mechanical experiment was carried out on the model.
方法：利用DICOM数据建模法，建立下尖牙的三维有限元模型，模拟力学实验。
