Fig. 30 Fig. 29 “ Using an .018 SS archwire, out bends (off-center bends) were placed distal of the Fig. 31 lateral incisors to widen the arch. An .018 NUA was used to align the mandibular incisors.” Case 6 The patient presented with a symmetrical dental Class I platform, narrow arches, and a tongue thrusting habit leading to an anterior open bite (Fig. 29).
