2nd Stage of Ortho I

One year 4 months post banding (M) with 16x16 wires, UR3 is being distalized using UR7 as anchor (Fig.1), while the upper dental midline matches the facial one (Fig.2).  The anterior overjet remains large (Fig.3).  When UR3 is fully distalized, place posted wire to distalize U2-2 together.  U2-2 distalization seems to be slow with one 16 mm closed coil spring each side (between 7 and post) 1 year 10 months post banding.  Since the upper anterior PA shows mild root resorption at UR2 (Fig.4), a 14 mm closed coil spring is added each side (between 6 and post, Fig.5,6).
