Fig. 5From: Torque movement of the upper anterior teeth using a clear aligner in cases of extraction: a finite element studyThe rotation angle of 11 in the sagittal direction with different power ridge heights when the axial inclination of 11 was 105°. *When the power ridge height is 0.7 mm, the rotation angle of 11 was close to 0° and the displacement trend of 11 was most close to bodily movementBack to article page
