Abstract

Objective:The purpose of this study was to compare the clinical effect of GMD appliance and Pendulum appliance.Method:58 patients with Class II malocclusion were treated with GMD appliance and Pendulum appliance by maxillary molars distalization without extraction.The effects were evaluated through pre-and post-distalization cephalometric radiographs and the dental models analysis.Result:GMD appliance and Pendulum appliance both can move the maxillary molar successfully.The moving mode of the maxillary molar distalization by GMD appliance was nearly translation.Conclusion:The GMD appliance was an effectine intraoral patient-independence appliance for the maxillary molar distalization.
