为老年无牙颌患者全口义齿人工牙排列时提供临床参考依据。方法：对101例浙江籍正常青年进行颜面部瞳孔间距、上颌尖牙牙尖间距和口角间距测量并作相关分析。结果：上颌尖牙牙尖间距为36．02±2．06mm，瞳孔间距为59．70±3．54mm，口角间距为46．53±3．31mm。瞳孔间距与上颌尖牙牙尖间距之比为1：0．603。两者之间存在显著相关性（P＜0．01）。结论：测量正常青年瞳孔间距、上颌尖牙牙尖间距，口角间距可为老年无牙颌患者全口义齿修复时提供上颌人工失牙定位依据。
It provides a clinical reference for the arrangement of artificial dentures for complete dentures in elderly edentulous patients. METHODS: A total of 101 normal young people from Zhejiang Province were studied for facial pupillary distance, maxillary cusp cusp spacing, and the distance between mouth angles. Results: The cusp spacing of the maxillary canines was 36.02±2.06mm, the pupil distance was 59.70±3.54mm, and the distance between the mouths was 46.53±3.31mm. The ratio of interpupillary distance to maxillary canine cusp spacing was 1:0.603. There was a significant correlation between the two (P<0.01). Conclusion: The measurement of normal pupillary distance, maxillary cusp cusp spacing, and angular distance between mouths can provide the basis for the positioning of maxillary artificial teeth during the complete denture restoration in the elderly edentulous patients.
