摘　　要：目的:设计一种矫正器和相应的矫正方法,用于推磨牙向后,开辟间隙,矫正由于磨牙前移导致的颊侧低位萌出的上颌尖牙,以及单纯上后牙前移造成的中度上牙弓牙性前突。方法:先取模制作上颌第一前磨牙和第一磨牙带环,再将4个带环在口内就位;第2次取印模灌制石膏模型,然后在有4个带环的模型上制作磨牙远移器;将其取下在患者口内就位,并在导杆上套装推簧,用以加力。结果:使用该方法矫正4例患者,均在3个月内将双侧磨牙推向远中,为后续治疗开辟了间隙。结论:上颌磨牙远移器及其使用技术是远中移动上磨牙的有效方法。PURPOSE： To design a kind of appliance to open space for aligning cuspid which is buccally and gingivally malpositioned.This kind of appliance can also be used to open space for distal movement of the upper arch moderate protrusion. METHODS： At first , two bands of maxillary cuspids were made, then the two cuspid bands and additional two molar bands were put on the teeth respectively. After the impression was taken and poured, the molar distal jet was fabricated on the model. Finally, it was worn and one piece of coil was used to apply force to remove the molars distally. RESULTS： Four cases were treated using this appliance.Both molars were distally moved within three months, and the necessary space was gained for subsequent treatment. CONCLUSION： Maxillary molar distal jet is an effective appliance to open space and move the maxillary molars distally.
