Abstract
Objective:To investigate the effect of sliding-transpalatal arch anchorage with MBT appliance and anchorage with Tip-Edge plus appliance in the treatment of maxillary protrusion.Methods:Thirty patients with maxillary protrusion, aged 11-17 years old, were selected and divided into sliding-transpalatal arch-MBT group and Tip-Edge plus group after extraction of four first premolars.All the patients were treated by MBT tech-nique and Tip-Edge plus technique, respectively.Lateral cephalometric radiographs before and after treatment were taken and analyzed.Results:The average forward movement of first upper molar did not change in two groups.The lower incisors were intruded 3.93°with reference to mandibular plane in MBT group,while in Tip-Edge plus group lower incisors were protruded 1.53°.The vertical height of bimaxillary first molars increased in sliding-transpalatal arch-MBT group.Plane of occlusion clockwise rotation in the Tip-Edge plus group.Conclu-sion:Maxillary protrusion patients could be treated successfully with straight wire and Tip-Edge Plus technique.Sliding-transpalatal arch anchorage system is effective in the plane of occlusion control and backward movement of incisor.Lower incisors were intruded more in the Tip-Edge Plus group than in the straight-wire group.关键词
