Fig. 5

The effective contribution ratio of molar distal movement at a 0.25 mm step distance. The pie charts show the contribution ratio of molar distalization, anchorage teeth mesialization to the 0.25 mm step distance, and the other percentage were occupied by buccal tipping and rotation. A1, model A1; A2, model A2. Subimage a represents the contribution ratio of 2nd molar distalization in group set I with various traction forces. Subimage b represents the contribution ratio of 1st molar mesialization during the 2nd molar distalization. Subimage c represents the contribution ratio of the other undesired movements. Subimage d represents the contribution ratio of 1st molar distalization in group set II. Subimage e represents the contribution ratio of 2nd premolar mesialization during the 1st molar distalization. Subimage f represents the percentage of other undesired movements
