图2 CBCT影像中的测量基线与测量参数示意图 Note： A. Sagittal measurements of tooth movement in group G at crestal (Lg1), mid-root (Lg2), and apical (Lg3) levels. B. Sagittal measurements of bone remodeling in group G at crestal (Bg1), mid-root (Bg2), and apical (Bg3) levels. C. Sagittal measurements of tooth intrusion movement in group G. Ha—apical retraction; Hc—coronal retraction; V—intrusion. D. Sagittal measurements of tooth inclination movement in group G. Δangle—labial inclination change.
