There is no precise scientific method for determining the correct edentulous occlusal vertical dimension. This study established the proportion between the ear-eye to chin-nose distance for determining reasonable occlusal vertical dimension. Two hundred white and 400 Asian men and women participated in this study. The ear-eye and chin-nose distances were measured with a modified craniometer. The results revealed that left ear-eye distance can be used to predict chin-nose distance with reasonable accuracy. However, the algorithm for making this prediction is not the same for combinations of sex and ethnic origin.
目前尚无精确的科学方法来确定正确的无牙颌咬合垂直距离。本研究确定了耳眼距与鼻颏距之间的比例关系，以确定合理的咬合垂直距离。200名白种人和400名亚洲男性及女性参与了本研究。使用改良的测颅器测量耳眼距和鼻颏距。结果显示，左耳眼距可用于较为准确地预测鼻颏距。然而，对于不同性别和种族的组合，进行这种预测的算法并不相同。
