title: [Clinical study of treatment effects on deep overbite: a comparison between Multiloop edgewise arch wire and manufactured artificial NiTi reverse-curve arch].
abstract: OBJECTIVE
  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.
