This study was designed as a reference of vertical dimension in prosthetic treatment. The author analyzed six facial measurements, namely, ①the height of lower face at maximum intercuspal position, ②the height of lower face at resting position, ③midface, ④external ear and lateral wall of orbit, ⑤interpupillary distance, ⑥distance between pupil and mouth in the 100 Won-kwang Univ. Dental collage students(50 : male, 50 : female), who have normal occlusion, no posterior prosthesis, no experience of orthodontic treatment, and no deformity of facial soft tissue and no temporomandibular dysfunction. @ES The results of this study were as follows: @EN 1. The length of midface was shortest and the inter-pupillary distance was longest in both male and female. 2. The length difference with the length of midface and lower face t maximum intercuspal position was 5.64mm in male and 2.23mm in female, so the lower face was longer. 3. The facial measuring component, similar to lower face at maximum intercuspation, was the length of between medial wall of external ear and lateral wall of orbit. It’s difference was 1.3mm in male, 1.77mm in female, and the lower face was shorter. 4. The difference of lower facial length in resting position and maximum intercuspation was 2.48mm in male, 2.24mm in female, the length of resting position was therefore longer. 5. The most clost correlation with the height of maximum intercuspal positioning lower face was resting lower face in both groups
