It is very difficult to reposition the upper central incisors or to assume and determine the vertical dimension when the upper anteriors and/or the occlusal stop by natural teeth were lost, although they are important esthetically and functionally. The faces of adult Japanese with normal occlusion were esthetically analyzed in order to make reference on the position of the upper incisors and the height of vertical dimension. The results were summerized as follows : 1. The triangle which was formed by left and right external ocular angle points and upper incisor point was nearly an equilateral triangle. It was thought as the facial triangle which had been reported the most important parts for facial expressions. 2. The height of the incisal edge of upper central incisors was quite close to the lip conjugate point. 3. The tip of the upper lip was coincident with the esthetic line, which is a line drawn between the pronasal point and the mental point, when the face was viewed from the lateral side. 4. The incisal edge of the upper central incisors was located 13mm anteriorly from the posterior edge of the incisive papilla. 5. The cross point of the left and right extended lines of the pupil point and the ala nasi point were coincident with the mental point. This can be used as a reference to judge the vertical dimension, esthetically.
