Abstract

In order to obtam the basic data of the movements of the mandible for orthodontic treatment and gnathosurgery of cleft individuals, the ranges and shapes of the movements of the mandible were measured in frontal, sagittal, and horizontal view with Saphon Visi-Tramer CII, in 19 adult cleft lip and palate individuals. The subjects included 5 BCLP, 9 UCLP, and 5 CLA patients. The measurements were compared with the values of normall mdividuals reported by Kang 1. Frontal view. The mean values for maximal laterotrusion were almost the same as those previously reported for the normal mdividuals. Mandibular deviation in maximal opening was usually toward the Typical shield was formed only in the CLA group. 2. Sagittal view ; The mean value for maximal protrusion was not different from that of normal troup and antero-posterior deviation showed a significant difference. The angle of maximal protrusion and horizontal plane was less than that of normal group. 3. Horizontal view, The mean values for maximal laterotrusion and protrusion were not different from those of the normal group. The angle of the laterotrusion and horizontal plane was larger in the left and smaller in the right.
