Brackets and Bands will be placed 2 months post extraction (Fig.1-3: *).  UR7 (overjet; Fig.1 (7), 2 (arrow)) will be retracted early using LR6 and 7 as anchorages.  Because of good posterior interdigitation (Fig.1), U3 and LL3 will be distalized using closed coil spring between 3 and 6.  When this is finished, retract 4 incisors (each arch) together using a posted wire and the same closed springs.
