A 14-year-old man requests ortho because of crowding lower anterior and UR missing lateral (Fig.4). Black lines represent bracketing at UR1 and 3 to control root torque. Take parallel PA for UR1 and 3 prior to banding. In fact PA is taken 5 months post banding (Fig.9). The roots of neighboring teeth are parallel with new bone formation behind. The mesiodistal space is similar to that of the tooth #10 following consolidation of diastemata on the left.
