There is no specific scientific method for determining the correct edentulous occlusal vertical dimension. In this study, the establishment of the proportion between the ear-eye to chin-nose distance to determine occlusal vertical dimension.
200 dentulous Saudi students participated in this study. The chin-nose and eareye (right & left) distances were measured; the results showed that there is a correlation between these measurements; also this study showed that this facial
measurement may be used to predict chin-nose distance and determining occlusal vertical dimension in edentulous patients of the Saudi population in combination with some other methods, which have proved to be helpful
