目的：对上颌前牙牙冠总宽度与鼻翼宽度的相关性及临床意义的研究。方法：选择北京地区男６１例女５５例正常合１１６例，对上前牙牙冠总宽度及鼻翼宽度进行测量采用计算机视频模型测量系统。结果：上前牙牙冠总宽度大于鼻翼宽度（Ｐ＜００１，ｒ＝０８２７）。各牙弓形无显著性差异（Ｐ＞００５），不同性别比较有显著性差异（Ｐ＜００１）。结论：鼻翼宽度测值为５２５７－７８９６ｍｍ，可做为全口义齿选上颌前牙牙冠总宽度的参考标准。
Objective: To study the relationship between the total crown width of the maxillary anterior teeth and the width of the alar wing and its clinical significance. Methods: A total of 116 male and 61 female patients were enrolled in this study. The total width and width of the anterior teeth crowns were measured. The computer video model was used to measure the system. Results: The total crown width of anterior teeth was larger than that of the nose (P <001, r = 0827). There was no significant difference in each dental arch (P> 005), with significant difference in different genders (P <001). Conclusion: The measured width of the alar wing is 5 257-7 896 mm, which can be used as a reference standard for the total width of the crown of the maxillary anterior teeth.
