Impaction of the anterior teeth, which is less frequent in central incisors, can cause serious esthetic and subsequent psychological problems for patients during the mixed dentition period. Traumatic injury to deciduous teeth is the most common etiologic factor. Thus, treatment of maxillary incisor impaction is highly important. Nowadays, application of laser has been suggested in orthodontics and pediatric dentistry for different treatments, such as surgical exposure of impacted teeth and application of low-level laser therapy (LLLT) for acceleration of orthodontic tooth movement. In this paper, the authors present treatment of an impacted and dilacerated maxillary central incisor with laser application for its surgical exposure and LLLT for acceleration of its orthodontic traction and eruption.
前牙阻生在中切牙中较少见，在混合牙列期会给患者造成严重的美观问题及后续心理问题。乳牙外伤是最常见的病因。因此，上颌中切牙阻生的治疗非常重要。如今，激光已被建议应用于正畸和儿童牙科的不同治疗中，如阻生牙的外科暴露以及应用低强度激光疗法（LLLT）加速正畸牙齿移动。在本文中，作者介绍了一例上颌中切牙阻生并伴有牙折的病例，采用激光进行外科暴露，并应用LLLT加速正畸牵引和萌出。
