영문 초록

Faces of normal occlusion, open bite and class-111 malocclusion were measured using cephalogram in 190 finale and female subjects. Using M.K.G., types of mandibular movement, amount of horizontal -and vertical movement were studied in relation to. occlusal types, and were compared with each other. The following conclusions were obtained. 1 Movement of protrusion was most different in relation to occlusal type. In normal occlusion, maximal protrusion were horizontal 7.66mm, vertical 3.01mm in male, 6.41, 2.92mm respectively in female and maximal inferior position were -24.32, 33.63mm in male, -23.48, 32.27mm respectively in female. 3. Angle between maximal inferior position and horizontal plane were 53.510 in male, 53.84° in female. 4. Generally, amount of mandibular movement was greater in male than female. 5. In open bite, path of protrusion was nearly straight without curve 69.2% in male, 70.2% in female. 6. In class III malocclusion, angle and amount of protrusion were smaller than normal occlusion and path was directed anterior-superiorly in 22.7%. 7. There was no correlation coefficient between measurement of face and mandibular movement.
