Fig. 6From: Different biomechanical effects of clear aligners in bimaxillary space closure under two strong anchorages: finite element analysisTipping movement of the second premolars under indirect strong anchorage control can be decomposed into two circular motions. A Circular motion around the button. B Circular motion around the miniscrew. C) Schematic diagram of the integral tipping movement of the second premolarsBack to article page
