Fig. 3From: Evaluation of cuspid cortical anchorage with different sagittal patterns using cone-beam computed tomography: a retrospective studyThree levels of the cuspid root. A1: the apical point of the cuspid; A2: the mid-root point of the cuspid; A3: the cervical-root of the cuspid; D: the intersection of the long axis of the cuspid and the CEJ; L1: the apical-root level; L2: the mid-root level; and L3: the cervical-root levelBack to article page
