Canines Extrude or Incisors Intrude?
Immediate post banding, 14 niti wires bend abrupt at 3s (Fig.1-3). With arch wire sequence, will the canines extrude or the incisors intrude? L7s erupt ~7 months post banding. Bands are placed. It is difficult to insert 18 ss wire (from 18 niti for 2 appointments (coronavirus pandemic in between)) into the buccal tube of LL7 ~ 4 months later, which may be related to the linguoversion of the tooth (Fig.5 vs. 4). Interarch retraction is added.
