目的：比较有齿和完全无牙受试者的下面部高度（下巴-鼻下根部和下巴-鼻尖根部）与不同人体测量值的关系。方法与材料：本研究选取男性受试者132例（1组[G1]，有牙列120例；2组[G2]，完全无牙列12例）。G1组和G2组采用改良卡尺测量下颌-鼻下量尺（FM1）、下颌-鼻尖量尺（FM2）、Willis量尺（FM3）、眉间-鼻下量尺（FM4）、食指长度量尺（AM1）、拇指-食指尖量尺（AM2）， G1组以中心咬合闭合，G2组以中心咬合闭合上颌、下颌全口义齿。统计学分析采用配对t检验、Pearson相关（PC）和回归分析。结果：G1FM1与G1FM3、G1FM1与G1FM4、G1FM1与G1AM2之间差异无统计学意义（P < 0.05）， PCs分别为R = 0.74、R = -0.35、R = -0.32。G1FM2与G1FM3、G1FM2与G1FM4、G1FM2与G1AM2之间存在显著性差异（P = 0.05）， G2FM2与不同测量值的G2之间存在显著性差异（P = 0.05）。结论：推荐使用线性方程预测下颌-鼻下测量的可能基础，可作为咬合垂直尺寸丢失后修复咬合垂直尺寸的指导。
Objective: The aim was to compare two measurements of lower facial height (base of chin-subnasale and base of chin-tip of the nose) as related to different anthropometric measurements in dentate and completely edentulous subjects. Method and Materials: This cross-sectional study was conducted on 132 male subjects (group 1 [G1], 120 dentate subjects; and group 2 [G2], 12 completely edentulous subjects). Base of chin-subnasale measurement (FM1), base of chin-tip of the nose measurement (FM2), Willis' measurement (FM3), glabella-subnasale measurement (FM4), length of the index finger measurement (AM1), and tip of thumb-tip of index finger measurement (AM2) of subjects of G1 and G2 were measured by using a modified caliper while the subjects in G1 closed in centric occlusion, and the subjects of G2 were asked to close the maxillary and mandibular complete dentures in centric relation. Statistical analysis was carried out by using paired t test, Pearson's correlation (PC), and regression analysis. Results: There were no significant differences between G1FM1 and G1FM3, G1FM1 and G1FM4, G1FM1 and G1AM2 (P >.05), and PCs were R = 0.74, R = -0.35, and R = -0.32 respectively. However, there were significant differences between G1FM2 and G1FM3, G1FM2 and G1FM4, G1FM2 and G1AM2 (P =.05), and there were significant differences between G2FM2 and different measurements of G2 (P =.05). Conclusion: The use of the linear equation to predict the possible base of chin-subnasale measurement through the Willis' measurement was recommended and could be used as a guide during restoration of the vertical dimension of occlusion when it has been lost.
