Fig. 3

The tendency for displacement of the anterior dentition in the groups with different spaces. A The pattern of stress distribution of the anterior dentition and the direction of the tendency. B The anterior dentition’s tendency for displacement in the sagittal direction. C The anterior dentition’s displacement in the vertical direction. D The degree of extrusion under the conditions of similar sagittal movement. (The degree of the extrusion = vertical movement/sagittal movement)
