Fig. 5From: The three-dimensional displacement tendency of teeth depending on incisor torque compensation with clear aligners of different thicknesses in cases of extraction: a finite element studyThe displacement tendency in sagittal and vertical direction for central incisors with different height power ridges by 0.75 mm-thick aligner. The right ordinate represented the rotation angle of central incisors in sagittal direction (°), the left ordinate represents the displacement of central incisors in vertical direction(mm), and the abscissa represents the height of the power ridge(mm); The power ridge was 0.25 mm when bodily movement was achieved for central incisors with 0.75 mm-thick alignerBack to article page
