Following evaluations were made: 1) L6 to L7 angle 2) L6 to occlusal plane 3) L7 to occlusal plane 4) L6 to mandibular plane 5) L7 to mandibular plane 6) occlusal plane angle 7) mandibular plane angle Following results were obtained: 1. Significant differences between T group and N group were not seen in the occlusal plane angle. 2. A majority in the T group showed a mesial inclination of the lower second molar. 3.
