摘要: 目的 探讨磨牙后区微种植体应用于下颌近中阻生第二磨牙竖直的正畸治疗方法,评估其效果。方法  选取江苏省口腔医院正畸科2011—2014年门诊下颌第二磨牙近中阻生的患者13例,采用磨牙后区植入微种植体,牵引23颗患牙向远中移动, 引导其竖直、萌出。结果 23颗阻生的下颌第二磨牙全部竖直萌出并建立良好的咬合。竖直治疗平均时间为6.5个月。结论 磨牙后区微种植体支抗能简单有效地竖直下颌阻生的第二磨牙,并且可以控制磨牙的垂直向高度, 避免对相邻牙齿产生不良影响。

Abstract: Objective To assess the use of microimplants in the retromolar area for the uprighting treatment of mesial impacted mandibular second molars. Methods  To select thirteen patients in the year of 2011-2014 who have mesial impacted mandibular second molar in Department of Orthodontics,Jiangsu Province Stomatology Hospital. Twenty-three impacted mandibular second molars were treated with the retromolar placement of a microimplant. Crowns of impacted molars were moved occlusally and distally. Results All of the twenty-three impacted mandibular second molars were uprighted and brought into occlusion.The average treatment period was 6.5 months. Conclusions  A microimplant as anchorage in the retromolar area is a more simple and effective application of force to upright the impacted molar. It will facilitate vertical control during the uprighting phase of treatment and avoid adverse effects to the adjacent teeth.

Key words: microimplant, uprighting, mesial impacted mandibular second molar
