Fig. 3

Total displacement of one-molar distalization with a step distance of 0.250 mm (a), two-molar distalization by 0.250 mm (b), and 0.130 mm (c), respectively. Arrows indicate the direction of tooth movement. The colder the tone, the less the tendency for tooth movement; the warmer the tone, the more the tendency for tooth movement
