Abstract:
OBJECTIVE:To evaluate the therapeutic effects of MBT straight wire on extraction case of Class II division I.
METHODS:Thirty-six class II division I malocclusion patients were treated with MBT straight wire by extracting 4 bicuspid premolars or 2 maxillary bicuspid premolars. The X-ray cephalograms were analyzed before and after the treatment of MBT straight wire.
RESULTS:After the treatment, the overjet was reduced by 6.04 mm (P < 0.01); U1-NA was reduced by 15.43 degrees (P <0.01); and U1-NA (mm) was reduced by 4.71 mm (P <0.01). ANB was significantly reduced (P < 0.05).
CONCLUSION:MBT straight wire not only shortens the operation but also shows superior effect for Class II division I malocclusion cases.
