| Abstract: | Objective To investigate the craniofacial and occlusal changes of Class III cases treated with Transmission straightwire technique. Methods eleven Class III patients were treated with transmission straightwire technique＋ Cephalometric analysis was perform to evaluate the changes before and after treatment. Resulls After teatment, ANB and wits was significantly smaller than before （P〈0.05）, the distants of the upper lip and lower lip to SnPg＇ was significantly smaller than before too （P〈0.01）. A remarkable craniofacial change was noted after treatment. Conclusions With transmission straightwire technique and light continuous force, teeth could tipped distally and lingually quickly. The hard and soft tissues changed accordingly. |
