摘　　要：目的:评估可摘矫治器压低伸长的磨牙的可行性和临床应用价值。方法:选择7例患者,随机采用可摘牙合板式矫治器和真空压膜式矫治器压低伸长的磨牙。治疗前后通过牙颌模型分析评价临床效果。结果:7例患者经过平均3.7个月的治疗均取得比较明显的治疗效果。治疗前后模型分析显示最大压入量为3.05 mm,最小为1.03 mm,月平均压入量为0.58 mm。结论:可摘矫治器用于压低伸长的磨牙有明显的临床效果。可摘矫治器具有美观、便于口腔卫生维护、制作简便、成本低廉的特点。Objective：To evaluate the feasibility of molar intrusion with a removable appliance and define whether this method had extensive clinical application or not.Method：Seven patients were selected.Removable bite aplliance or Vacuum moulding appliance were randomly chosen.The clinical effect of intrusion was evaluated by models.Result：All the overerupted molars had been intruded successfully in average 3.7 months.Pre and post-treatment models analysis demonstrated the maximum intrusion amount was 3.05 mm,minimum 1.03 mm and mean 0.58 mm per month.Conclusion：Molar intrusion with the removable appliance has a significant effect.This appliance has a significant value for clincal application,for esthetic,good for oral hygiene,simple fabrication and less cost.
