Summary

The purpose of this study was to determine the effect of auxiliary intrusion cantilevers used with resilient archwires during the leveling and alignment phase in intruding lower incisors.

Conditions

• Deep Overbite

Interventions

Type	Name	Description
DEVICE	Auxiliary cantilever intrusion arches on initial archwires	Patients received a full set of 0.022- inch slot brackets (Mini 2000, Ormco) with Roth prescription. Lower first molars received double tubed bands while 2nd molars received single bondable tubes. Leveling and alignment phase then started with 0.014 inch NiTi wires engaging all teeth and synched behind 2nd molars. Two 0.017" x 0.025" TMA (Ormco) sectional wires were attached to auxiliary tubes on 1st molars with tip back bends mesial to the molars and attached with hooks distal to lateral incisors on top of basal leveling arch wire. Amount of intrusive force was measured to range between 20 and 40 grams per side. Basal leveling arches were upgraded whenever needed. All patients were assessed after 6 months of treatment.
DEVICE	Routine leveling and alignment	Patients received a full set of 0.022- inch slot brackets (Mini 2000, Ormco) with Roth prescription, 1st and 2nd molars received tubes or bands according to each patient's further needs Lower arch was leveled and aligned with sequential wires starting with 14 NiTi and upgraded when needed. All patients were assessed after 6 months of treatment.
