OBJECTIVE
To assess the treatment method and outcome of mesially or horizontally impacted mandibular molars.
METHODS
Eleven patients with mandibular impacted molars, including 9 horizontally impacted molars and 5 mesially impacted molars were treated with fixed appliance in conjunction with molar band soldered with pushing spring. Crowns of impacted molars were moved occlusally and distally.
RESULTS
All mesially or horizontally mandibular impacted molars were uprighted and brought into occlusion. Mean treatment period was 7.4 months (6 to 12 months).
CONCLUSIONS
This orthodontic molar uprighting technique was effective in uprighting and distalizing the impacted molars.
目的
评估近中或水平阻生下颌磨牙的治疗方法及效果。
方法
11例下颌阻生磨牙患者，其中9颗为水平阻生磨牙，5颗为近中阻生磨牙，采用固定矫治器结合焊接推簧的磨牙带环进行治疗。将阻生磨牙的牙冠向咬合面及远中移动。
结果
所有近中或水平阻生下颌磨牙均得以直立并建立咬合关系。平均治疗时间为7.4个月（6至12个月）。
结论
这种正畸磨牙直立技术在直立和远中移动阻生磨牙方面是有效的。
