摘　　要：目的:探讨安氏Ⅱ类错非拔牙矫治中GMD矫治器的疗效和适应症。方法:选择36例恒牙早期安氏Ⅱ类病例,主要表现为以乳磨牙早失形成的磨牙近移或上牙列轻中度拥挤的的非拔牙患者为研究对象,通过运用GMD推磨牙装置远移磨牙开辟后牙间隙。结果:36例患者中除1例因上切牙唇倾致患者对面形不满意而改行拔牙矫治外其余患者均取得了较好的疗效。第一磨牙平均远移5.6mm,远移到位平均4-5个月。磨牙建立中性关系。结论:GMD装置是一种快速有效的推磨牙向后的矫治器,但要掌握好适应症才能取得成功。Objective： To evaluate the clinical effect of Greenfield Molar Distalization （GMD） appliance. Methods： A total of 36 patients with Class II malocclusion were treated with GMD appliance, without extraction. Then the effects were evaluated through pre- and post-distalization cephalometric radiographs and the dental models analysis. Results： GMD appliance can move the maxillary molar successfully. The moving mode of the maxillary molar distalization by GMD appliance is nearly translation. Conclusion： GMD device is a fast and effective, backward molar appliance. Mastering the indication is also the key to successful treatment.
