After alignment, Class II retraction will proceed to correct the overjet (Fig.10 top arrow). The impacted bicuspid will be extracted The retained primary molars will be extracted, while the lower molars will be mesialized (bottom arrow, compare Fig.9 and 10) with minimplants to be placed mesial to the most distal lower anterior teeth (LR4, LL3). The procedure will allow the lower third molars to occlude with the upper 2nd molars. An implant will be most likely placed in the LL bicuspid area (I).
