Preliminary options given were no treatment or comprehensive orthodontic therapy involving surgery to locate and connect the Fig. 13 Fig. 14 Fig. 16 Panoramic and 3D images extracted from CBCT imaging. Key points were impacted teeth angulations, #6 ectopic eruption pattern, #7 buccal-horizontal impaction, and distal-horizontal of #8. The planning of the anchorage TAD location is also depicted. Maxillary arch with shape and form developed with arch wire sequence. Consolidation of bicuspids and molars and initial eruption of #6 helped by retraction of #4 and #5. 32 Spring 2018 JAOS
