摘　　要：目的 探讨改良自攻螺纹钉辅助正畸牵引治疗下颌前磨牙低位埋伏阻生的疗效。方法 应用改良自攻螺纹钉,通过螺纹机械及粘接双重固位,配合正畸牵引,导萌50例低位阻生的前磨牙。结果 50例低位阻生牙均被牵引至正常位置,牵引钉无脱落,主动正畸结束后1、3、6个月测量其牙髓活力、牙根长度与对照牙相比差异无统计学意义(P>0.05)。结论 应用改良螺纹钉辅助正畸牵引在治疗低位阻生的前磨牙,固位力可靠,外科手术暴露面积相对较小,具有较大临床应用价值。Objective To investigate the clinical effect of modified tapping screw assisted orthodontic traction in the treatment of impacted mandibular premolars.Methods 50 cases of low impacted premolars were treated with modified tapping screw,double retention by thread machine and adhesive,and orthodontic traction.Results All the 50 cases of low impacted teeth were pulled to the normal position,there was no significant difference in pulp vitality and root length between the two groups at 1,3 and 6 months after active orthodontic treatment.Conclusion Modified screw assisted orthodontic traction in the treatment of low impacted premolars has reliable retention force,small surgical window,and a greater clinical value.
