Abstract

•
Early treatment of labially inversely impacted maxillary central incisors in the deciduous and mixed dentitions.
•
Apically positioned flap and the closed-eruption surgical techniques.
•
Orthodontic traction before the onset of root formation yields longer root length.
•
Although interdisciplinary treatment is challenging, the prognosis remains positive.
•
Inversely impacted incisors may require up to 2 years of treatment.

This article reports the combined surgical exposure and orthodontic treatment of labially inversely impacted maxillary central incisors in the deciduous and mixed dentitions. After being successfully moved into proper positions, one highly positioned impacted incisor had a short root with an obliterated root canal but showed an esthetically good and stable outcome 14 years after treatment. The other two impacted incisors had normal root morphology after treatment, similar to the roots of their contralateral central incisors. The surgical procedures and the orthodontic strategies for treating labially inversely impacted maxillary central incisors are described, along with a review of the current literature on the topic. The importance of early treatment for the root development of labially inversely impacted maxillary central incisors is also discussed.

上颌中切牙阴唇逆阻生的早期治疗

•乳牙和混合牙列上颌中切牙唇反阻生的早期治疗。•顶端定位皮瓣和闭合出露手术技术。•在牙根形成开始前进行正畸牵引可使牙根长度更长。•尽管跨学科治疗具有挑战性，但预后仍然是积极的。•倒阻生门牙可能需要长达2年的治疗。本文报道乳牙和混合牙列上颌中切牙唇反阻生的手术暴露与正畸联合治疗。在成功移动到适当位置后，一名高度定位的阻生切牙根短根管闭塞，但在治疗14年后显示出良好和稳定的美观结果。另外2个阻生切牙治疗后牙根形态正常，与其对侧中切牙牙根形态相似。本文描述了治疗上颌中切牙阴唇逆阻的外科手术和正畸策略，并对当前有关该主题的文献进行了综述。文中还讨论了早期治疗对上颌中切牙根发育的重要性。本文报道乳牙和混合牙列上颌中切牙唇反阻生的手术暴露与正畸联合治疗。在成功移动到适当位置后，一名高度定位的阻生切牙根短根管闭塞，但在治疗14年后显示出良好和稳定的美观结果。另外2个阻生切牙治疗后牙根形态正常，与其对侧中切牙牙根形态相似。本文描述了治疗上颌中切牙阴唇逆阻的外科手术和正畸策略，并对当前有关该主题的文献进行了综述。文中还讨论了早期治疗对上颌中切牙根发育的重要性。
