Objective:To evaluate the soft and hard tissue changes of class II division 1 patients treated by Dynamax appliance. Methods:15 class II division 1 cases, whose hand-wrist radiographs were in FG-G stage, were treated by Dynamax appliance. After scanning the cephalometric tracing and transcripting into the special software of Winceph 7.0, the Cephalometrics analysis was preformed on pre-treatment and post-treatment. Results:After being treated by Dynamax appliance, the SNB, Co-GN,L1-NB,Cm-Sn-Ls was increased significantly,the ANB,Wits,U1-NA,overjet,overbite,Ns-Sn-Pos decreased significantly. Conclusion:Dynamax can effectively induce forward movement of mandible, improved esthetics on soft tissue profile and make face become normal.
