BACKGROUND
Root resorption of adjacent teeth due to impacted canines is common, and orthodontic treatment often leads to secondary resorption or even loss of adjacent roots. Clinical reports of long-term stability after treatment are rare.
CASE PRESENTATION
This study reports two cases of maxillary impacted canines resulting in severe root resorption of the adjacent lateral incisors. Surgical exposure, orthodontic retraction, and alignment of the impacted canines were successful in both cases, and the resorbed lateral incisors were stable with no significant loosening and normal pulp vitality after treatment and at the 5- and 10-year follow-up appointments.
CONCLUSIONS
Light orthodontic force may be used to move adjacent teeth with root resorption due to tooth obstruction. The path and direction in which the teeth are moved must be specifically designed so that the adjacent roots are not resorbed and so long-term stability can be achieved.
背景
由于阻生导致的邻牙牙根吸收在临床上较为常见，正畸治疗常导致继发吸收，甚至邻牙根丧失。治疗后长期稳定的临床报告较为少见。
病例报告
本研究报告了两例上颌埋伏尖牙导致邻侧切牙严重牙根吸收的病例。两例患者的手术暴露、正畸牵引和埋伏尖牙的排齐均获得成功，治疗后和 5 年、10 年随访时，吸收的侧切牙无明显松动，牙髓活力正常。
结论
对于因牙阻生导致邻牙牙根吸收的病例，可以采用轻力的正畸方法移动牙齿。移动的路径和方向必须具体设计，以避免邻牙根吸收，从而实现长期稳定。
