DETERMINATION OF ESTHETIC REFERENCE PLANE FOR SEMI-ADJUSTABLE ARTICULATORS

The purpose of this study is to evaluate suitable anterior reference point similar to esthetic reference plane of the patient while transferring the suitable facebow. So those who live in Pusan with the normal occlusal relationship were chosen as subjects. The esthetic reference planes determined by the participants themselves and the superior reference line (anterior reference point) in Hanau & Denar articulator were compared with F-H plane in the standard lateral cephalogram. The results were as follows. 1. The angle between the esthetic reference plane and F-H plane was $2.81{\pm}5.7^{\circ}$. 2. The reference line, 43mm from Beyron point to the edge of the upper incisor, was the reference plane that had the closest paralleled relationship with the esthetic reference plane. 3. Transferring with ear piece type face-bow, the anterior reference point that showed the esthetic reference plane was 17mm below orbitale or 43mm above, the edge of the upper incisor.
