摘要
埋伏牙是指由于萌出受阻或萌出方向与位置错误而无法正常萌出的牙齿。埋伏牙中最常见的是第三磨牙,前牙区最常见的是上颌尖牙,其次是上颌中切牙和上颌侧切牙。近年来,上颌切牙埋伏阻生的治疗常使用封闭式导萌术或开放式导萌术配合牵引,大部分预后较好;但当牙根弯曲时,常遇到牵引困难、牙根吸收和牙槽骨吸收等问题。文章对上颌切牙埋伏阻生的治疗研究进展作一综述。
An impacted tooth is a tooth that cannot erupt normally when its eruption is blocked or it is erupted in the wrong direction and position.The most commonly impacted teeth is the third molar,while in the anterior region,the most common is the maxillary canine,followed by the maxillary central incisor and the maxillary lateral incisor.In recent years,the treatment of impacted maxillary incisors often uses open and closed eruption techniques with traction.Although most of the prognosis is good,traction difficulties,root resorption and alveolar bone loss are often encountered in the case of root dilacerations.This article reviews the progresses in the treatment of impacted maxillary incisors.
