问题陈述：选择合适尺寸的上颌前牙是全口义齿美学中困难的临床步骤之一。已经有几项研究报告建立了估计上颌前牙组合宽度的方法。 目的：本研究的目的是确定内眦距离 (ICD) 和房间隔宽度 (IAW) 与上颌前牙组合宽度之间是否存在关系。 材料和方法：检查了 600 名成人受试者的上颌前牙。 ICD 是在睑裂正中角之间测量的。 IAW 是在鼻翼最宽处之间测量的。上颌前牙的平均组合宽度在口内测定其最宽尺寸。计算Pearson相关系数以确定ICD、IAW与上颌前牙总宽度之间的关系（α=0.05）。结果：虽然Pearson相关系数较小，但内眦尺寸与IAW之间存在显着相关性（P<0001）。结论：在本研究的局限性内，结果表明ICD和IAW不能作为确定上颌前牙宽度的初步方法。无牙颌患者的前牙。
STATEMENT OF PROBLEM: Selection of proper sized maxillary anterior teeth is one of the difficult clinical steps in complete denture esthetics. Several studies have been reported to establish methods of estimating the combined width of maxillary anterior teeth.PURPOSE: The aim of this study was to determine whether a relationship exists between the innercanthal distance (ICD) and interalar width (IAW) with the combined width of maxillary anterior teeth.MATERIAL AND METHODS: The maxillary anterior teeth of 600 adult subjects were examined. ICD was measured between the median angles of the palpebral fissure. IAW was measured between the ala of the nose at their widest point. The mean combined width of the maxillary anterior teeth was determined intraorally at their widest dimension. Pearson's correlation coefficients were calculated to determine the relationship between ICD, IAW and the combined width of maxillary anterior teeth (alpha =0.05).RESULTS: Although the Pearson correlation coefficients were relatively small, a significant relationship existed between innercanthal dimension and IAW (P < 0001).CONCLUSION: Within the limitations of this study, the results suggest that ICD and IAW cannot be used as a preliminary method for determining the width of the maxillary anterior teeth for edentulous patients.
