摘要/Abstract

摘要：

目的探讨上前牙区多颗相邻埋伏牙的导萌方法。方法选择9例患者的22颗相邻埋伏牙为研究对象，常规拍摄定位X线片，再配合口内检查及模型分析，确定埋伏牙的位置及相互关系，决定拔除或外科手术-正畸联合导萌埋伏牙。结果22颗相邻埋伏牙中，19颗埋伏牙通过外科手术-正畸联合导萌后顺利进入正常牙弓，未见牙根吸收、粘连，建立了良好的咬合关系；3颗牙根弯曲畸形的中切牙被拔除。9例患者的平均治疗时间为19个月。结论只要正确判断位置，掌握牵拉的适应证，相邻的多颗埋伏牙可以牵引入正常牙弓，恢复正常的咀嚼功能及美观。

Abstract:

Objective To study the method of induced eruption on multiple adjacent impacted teeth in anterior maxillary bone. Methods Twenty-two multiple adjacent impacted teeth of 9 cases were chosen. The position of the impacted teeth and the relationship to each other were assessed on X-ray images, oral examination and plaster model. The impacted teeth were extracted or induced erupted with the closed-eruption technique and fixed orthodontic appliances. Results Of 22 impacted teeth, 19 impacted teeth were moved into arches by induced eruption with the closed-eruption technique and fixed orthodontic appliances. There were not root adsorption or conglutination for 19 impacted teeth. Three impacted teeth with deformed root were extracted. The average time for treatment was 19 months. Conclusion With correct diagnosis, reasonable design, the complicated impacted teeth could be moved into alignment with good esthetic and functional effect.

Key words: multiple adjacent impacted teeth, induced eruption, localization
