The author studied on the tongue position, tongue space and intermaxillary space at 4 groups; normal occlusion 30 cascs, Angle’s Class I bimaxillary protrusion 29 cases, Angle’s Class II malocclusion 26 cases, Angle’s Class III malocclusion 26 cases. This study used the data from cephalometric films of female subject aged from 16 to 23 years. Following results were obtained; 1. Dorsa height in Angle’s Class III malocclusion was greater than normal occlusion. 2. Anterior Intermaxillary Height in Angle’s Class I bimaxillary protrusion and Angle’s Class III malocclusion was greater than normal occlusion. 3. Tongue space in Angle ’s Class I bimaxillary protrusion was greater than normal occlusion. 4. The ratio of the tongue space to the intermaxillary space (T.S./I.S.) in Angle’s Class II malocclusion was greater and the ratio in Angle’s Class III malocclusion is lesser than normal occlusion.
