영문 초록

This study was undertaken to find out oropharyngeal movement of the class III malocclusion patients during swallowing by using the cinefluoroscopic method. The experimental group was composed of fifteen male adults with class III malocclusion whose mean age was 24.4 yrs. The control group was composed of fifteen male adults with normal occlusion whose mean age was 24.8 yrs. The results were as follows 1. The horizontal position of the tongue tip was more anterior in the class III malocclusion group than in the normal group through all stages. 2. The tongue level was lower in the class III malocclusion group than in the normal group during stage 1, stage 3, and stage 4. 3. The horizontal position of the hyoid bone was more anterior in the class III malocclusion group than in the normal group during stage 1 only. 4. The tip of the soft palate was lower in the class III malocclusion group than in the normal group during stage 1 only, and there was no significant difference in the velar movement between the class III malocclusion group and the normal group during swallowing. 5. There was a significant difference in the interincisal distance, but no significant difference in the intermolar distance between the class III malocclusion group and the normal group through all stages. 6. Among 4 stages of each group, there was a significant difference in the movements of the dorsum of the tongue, the hyoid bone, and the soft palate. And there was a significant difference in the movement of the tongue tip of the normal group, but no significant difference in the movement of the tongue tip of the class III malocclusion group.
