本研究的目的是为了确定在鼻翼最宽处测量的IAW与上颌前牙的其他两个测量值之间的关系。其他测量，这两个都是重要的选择和安排的人工牙用于全口义齿，测量上颌尖牙远中面至对侧尖牙远中面的ICTW和ARCD，无性别和年龄差异，ICTW平均值为35.35 mm，平均ARCD为44.85 mm，比平均IAW 34.28 mm大31%。（小于1毫米的差异）根据Shillingburg等人的牙齿尺寸研究，构建的ARCD为45.8 mm。ARCD为44.85 mm。在先前的研究中没有进行过该测量，当IAW与尖牙间尖端宽度作图时，显示出相当强的相关系数0.413。当牙间宽度与上颌尖牙远中面至远中面的圆周弧距离作图时，观察到较弱但确定的相关系数为0.217。
This study was undertaken to determine the relationship of the IAW, measured between at the widest dimension of the alae of the nose, and two other measurements of maxillary anterior teeth. The other measurements, both of which are significant in the selection and arrangement of artificial teeth used in complete dentures, were the ICTW and the ARCD measured from the distal surface of the maxillary canine on one side of the arch to the distal surface of the canine on the opposite side of the arch. No distinction was made between either the sex or the age of the subjects.The mean ICTW of 35.35 mm was 3% greater than the mean IAW of 34.28 mm. The mean ARCD of 44.85 mm was 31% greater than the mean IAW of 34.28 mm. This mean ARCD compares favorably (<1 mm difference) with a constructed ARCD of 45.8 mm from a tooth dimension study by Shillingburg et al.8The ARCD was 44.85 mm. This measurement had not been made in the previous study examining the relationship of interalar distance to ICTW.When the IAW was plotted against the intercanine cusp tip width, a fairly strong correlation coefficient of 0.413 was exhibited. A weaker but definite correlation coefficient of 0.217 was observed when the interalar width plotted against the circumferential arc distance from distal surface to distal surface of the maxillary canines.
