摘要/Abstract

摘要： 目的探讨变异式保持器治疗第一恒磨牙异位萌出的临床应用效果。方法选择临床25例上颌第一恒磨牙异位萌出的患儿，年龄7~9岁，其中10例双侧，15例单侧，通过传统的Nance弓焊接远端牵引钩，在异位萌出的第一恒磨牙牙合面，联合应用链状橡皮圈推第一恒磨牙向远中以达到其正常的生理位置。结果 25例接受治疗的患儿均完成了治疗，且疗效明显，异位的第一恒磨牙均萌出到了正常位置。结论变异式保持器用于治疗第一恒磨牙异位萌出疗效显著，操作简便，适合在临床推广。

Abstract: Objective To evaluate the clinical application effect of modified retaining appliance in the treatment of ectopic eruption of first permanent molar. Methods The subjects consisted of 25 children aged from 7 to 9 with ectopic eruption of the first maxillary permanent molar, 10 of which were bilateral and 15 of which are unilateral. By welding the distal extension hook via traditional Nance arch and bonding the lingual button on the first permanent molar, the first permanent molar was moved distally to the normal position using chain rubber band. Results All the children completed the treatment and acquired good curative effect that the first permanent molar with ectopic eruption was moved to the normal position. Conclusion The modified retaining appliance can be utilized as a simple and more effective way of correcting ectopic eruption of first permanent molar.
