Purpose:
To evaluate the effects of multiloop edgewise arch wire(MEAW) and NiTi reverse-curve arch in correcting deep overbite.
Methods:
Twenty cases(12-27 year of age)with deep overbite were treated with MEAW or NiTi reverse-curve arch. Pre-and post-treatment cephalogram were taken and analyzed. SPSS13.0 software package was used for paired t test.
Results:
Two methods could intrude incisors and extrude molars.Maxilla and mandibular had no apparent changes, but less time was spent in the MEAW group.
Conclusions:
Two methods could correct deep overbite by the same mechanism, but the MEAW has more effective results.
