abstract: 'Willis' methods is one of the methods used to determine the vertical dimension of occlusion, where the upper facial height from the pupil of the eye to the rima oris, is presumed to be equal to the lower facial height, which is the vertical measurement from the base of the nose to the lower border of the chin, when the teeth are in occlusion. Results of this study shows that the two measurements are not equal. The upper facial measurement is longer than the lower facial measurements by 3 cm.
