摘　　要：目的通过临床应用阻生磨牙竖直器配合使用阻生磨牙直立牙挺辅助矫治近中倾斜阻生的下颌第三磨牙,检验其疗效。方法选择9名下颌第三磨牙近中倾斜阻生患者使用阻生磨牙竖直器配合使用阻生磨牙直立牙挺进行正畸治疗,共有15颗下领阻生齿需要治疗。测量矫治前后的曲面断层片下颌第二磨牙和第三磨牙的倾斜角,对比分析矫治前后倾斜角度变化,进行配对t检验。分别测量治疗前后下颌第二磨牙长轴与下颌升支后缘切线、双侧乙状切迹最下缘连线及双侧突顶点连线交角,独立样本t检验表明,矫治前后角度变化无统计学意义(P>0.1)。结果全部患者矫治效果良好,近中倾斜阻生的第三磨牙实现直立。第二、三磨牙的夹角倾斜度平均减少(55.47±22.07)°,具有显著的统计学意义(P<O.05)。第二磨牙治疗前后倾斜度改变无统计学意义(P>0.1)。结论阻生磨牙竖直器配合使用阻生磨牙直立牙挺是一种竖直近中倾斜阻生磨牙的简单高效的方法。Objective To evaluate the clinical effect of the molar uprighting device combined with uprighting elevator in the treatment of impacted mandibular third molars.Methods Nine patients with impacted third molars were treated with the molar uprighting device and the elevator.The inclination angles of mandibular second and third molars were measured before and after orthodontic treatment.Results All patients had good orthodontic effects and their impacted third molars were uprighted.The angle inclination of the second and third molars decreased(55.47±22.07)°,with significant statistical significance(P<0.05).Conclusions Impacted molar uprighting device combined with an elevator for impacted molars uprighting is a simple and effective method for uprighting impacted molars.
