Abstract:
Objective To examine the effects of fixed appliance and micro-implant on the improvement of facial profile in patients with protruding.Methods 30 protruding cases were treated by fixed appliance and micro-implant.Cephalometric data before and after treatment were measured and analyzed to assess the effects.Results The upper incisors were retracted 6.5 mm.The upper lip was retracted 3.8 mm.The lower incisors were retracted 5.8 mm.The lower lip was retracted 5.6 mm.UL-E was retracted 3.21 mm.LL-E was retracted 3.67 mm.NLA was changed from 86.7°to 103.7°.The U1-SN,U1-Y,L1-MP,L1-Y,UL-Y,LL-Y,UL-E,LL-E,and NLA demonstrated significant differences between pre-and post-treatment.Conclusions Fixed appliance and micro-implant might retract the anterior teeth and lead to an improvement of facial profile.
