摘　　要：上颌埋伏阻生中切牙的治疗方法主要有减阻助萌法、外科手术暴露联合正畸牵引法和拔除法等。减阻助萌法仅适用于正位埋伏且尚具有萌出潜力的牙齿,其预后一般较好。外科手术暴露联合正畸牵引法是目前临床上最常采用治疗埋伏牙的方法,外科手术暴露方法主要有开放式导萌法和封闭式导萌法。其中,封闭式导萌法的效果更好。正畸牵引中支抗的设计、牵引的位置和方向以及牵引的力值大小最为重要。拔除法和其他的治疗方法在临床上较少采用,主要是用来治疗弯根埋伏牙。Treatments for the maxillary impacted central incisors consist of many approaches,such as resistant reducing technique,surgical exposure combined with orthodontic traction,surgical extraction.Resistant reducing technique is just suitable for the maxillary impacted incisor with normal position and having the potential of growth,and usually it can receive a good result.Surgical exposure combined with orthodontic traction is the most popularly technique used in clinic.Surgical techniques include open eruption exposure and closed eruption exposure,and the latter is better.The most important thing in the orthodontic traction is the design of anchorage,position,direction and force of the traction.Surgical extraction and other techniques are mainly used for dilacerated impacted incisors,so they are seldom used in clinic.
