摘　　要：目的探索前牙反牙合伴严重牙列拥挤病例非拔牙矫治的新方法。方法通过应用多用途口外弓矫治前牙反牙合伴严重牙列拥挤患者12例,在推磨牙远移的同时前牵引上颌,可以在较短的时间内为拥挤的牙齿提供间隙。结果 12例患者通过治疗在较短的时间内磨牙远移的同时矫治了前牙反牙合,并为拥挤的牙齿提供间隙,从而避免拔牙矫治。结论多用途口外弓将口外弓与前牵引合二为一,利用前牵引上颌的反作用同时推磨牙远移,可与头帽配合使用,可缩短疗程,有效减少拔牙矫治的病例。Objective To explore the new method of non-extraction treatment of anterior crossbite with severe crowding cases. Methods With the application of multi-purpose face bow in 12 cases with anterior crossbite and severe crowding,maxillary protraction and molar distalization were going on at the same time,so some clearance was provided in a short period of time for crowded teeth. Results Molar distalization was achieved and the anterior crossbite of 12 patients was corrected within a short period of time and some gaps between teeth were provided for crowded teeth,so the extraction treatment had been avoided. Conclusions The multi-purpose face bow is composed of face bow and maxillary protraction. The reverse reaction of maxillary protraction can lead to molar distalization. It can be used together with headgear. It can significantly improve the efficacy and shorten the course of treatment. The clinical application of this appliance can be effective in reducing cases of extraction treatment.
