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 (less than 1 mm difference) with a constructed ARCD of 45.8 mm from a tooth dimension study by Shillingburg et al. The 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.
本研究旨在确定鼻翼最宽处测得的鼻翼间宽度（IAW）与上颌前牙的另外两项测量值之间的关系。另外两项测量值，即在全口义齿人工牙的选择和排列中均具有重要意义的，是从牙弓一侧上颌尖牙远中面到牙弓另一侧尖牙远中面测得的尖牙间宽度（ICTW）和圆周弧距离（ARCD）。研究未对受试者的性别和年龄进行区分。35.35mm的平均ICTW比34.28mm的平均IAW大3%。44.85mm的平均ARCD比34.28mm的平均IAW大31%。该平均ARCD与希林伯格等人牙齿尺寸研究构建的45.8mm的ARCD相比（差异小于1mm）具有优势。ARCD为44.85mm。在之前研究鼻翼间距离与ICTW关系的研究中未进行此测量。当将IAW与尖牙间牙尖宽度绘制在一起时，呈现出相当强的相关系数0.413。当将鼻翼间宽度与上颌尖牙远中面到远中面的圆周弧距离绘制在一起时，观察到较弱但确定的相关系数0.217。
