摘　　要：目的:对比MBTTM直丝弓托槽-7°和+7°尖牙托槽在矫治尖牙牙根突出患者远中移动尖牙的速度。方法:选择20例成人上颌尖牙根颊向冠舌向倾斜患者,拔除14、24、34、44,设计为微种植钉支抗,用MBT直丝弓矫治技术,随机选择10例为实验组,使用+7°托槽,另10例为对照组使用常规-7°托槽,分别远移上颌尖牙,测量上颌尖牙移动距离。结果:实验组尖牙移动速度快于对照组。结论:对尖牙牙根颊向突出的患者,使用+7°托槽移动尖牙速度快于常规-7°托槽,建议临床优先采用。Objective Contrast MBTTM Straight Wire Appliance -7°and ＋7°canine bracket orthodontics canine eminence patients on the movement speed of canine distalization. Methods 20 maxillary labial root and lingual crown tip patients were selected who needed treatment by extracting the first premolar 14,24,34,44,and micro-implants as anchorage.Used MBT Straight Wire Appliance,10 patients were chosen randomly as experimental group used ＋7°canine bracket,another 10 patients as control group,maxillary canine distalization respectively,the movement distances of canine were measured and analyzed statistically. Results Experimental group canine distalization faster than control group. Conclusion Orthodontics the patients of canine eminence,use ＋7°canine bracket is faster than use -7°canine bracket,clinical give priority to the suggestion.
