摘要
目的:评价片段弓技术远中直立严重近中倾斜阻生的下颌第二磨牙的疗效。方法:选择7例,共12颗下颌第二磨牙严重近中倾斜阻生病例,采用片段弓技术远中直立近中倾斜阻生的第二磨牙,观察倾斜牙直立的临床效果和所需时间,通过头影测量和曲面断层片评价其疗效。结果:采用片段弓技术远中直立严重近中倾斜阻生的第二磨牙,平均疗程3个月,12颗第二磨牙近中倾斜角从68.42°±5.99°增加为102.85°±4.84°,平均增加34.42°±9.34°,差异具有显著统计学意义(P<0.01)。结论:采用片段弓远中扶正近中倾斜阻生的下颌第二磨牙是一种简便,有效的方法,临床效果满意。
Objective:To assess the treatment method and outcome of mesially impacted second molars. Method: 7 patients with mesially impacted 12 second molars were treated with segmented springs,then evaluated the effect and period of treatment by cephalometry and panoramic radiograph. Result:The method of segmented springs can quickly and conve-niently upright mesially impacted molars. Mean treatment period was 3 months,The mandibular second molars' mesially in-clined angle increased from 68.42±5.99° to 102.85±4.84°,increased by 34.42±9.34°,there were Significantly differences be-tween the groups before and after treatment. Conclusion:This orthodontic molar uprighting technique was an easy and reli-able way to upright the impacted molars,the outcome is Satisfying.
