All 8s are present and developing. The cephalometric analysis (Figure 4; Table 1) indicates a mild skeletal Class III sagittal relationship (ANB = 1.9°, Wits = −4.8 mm) and hyperdivergent growth pattern (SN-MP = 41.9°). The maxillary incisors have normal inclination (U1-SN = 106.4°), and the lower incisors are mildly retroclined (IMPA = 86.6°). The American Board of Orthodontics (ABO) Discrepancy Index score of this case is 38 (Figure 5). Figure 4. Pretreatment panoramic radiograph (left) and lateral cephalogram (right) Figure 5.
