摘　　要：第二恒磨牙异位萌出若未得到及时治疗,会导致相邻的第一磨牙牙体组织吸收、牙齿早失、咀嚼效率下降及其他严重的错𬌗畸形。及时发现和处理第二恒磨牙异位萌出,对预防青少年错𬌗畸形、建立正常咬合关系具有重要的意义。然而,目前针对下颌第二恒磨牙异位萌出的病例报告比较少见,大多治疗方法主要为手术及正畸的方式,且缺乏长期的随访。本文报道1例采用铜丝结扎法治疗下颌第二恒磨牙异位萌出,使恒牙顺利萌出并建立正常咬合。术后观察5年,咬合稳定,牙根发育、牙髓活力及牙周状况正常。本文为近中倾斜度不大且已经部分萌出的阻生年轻下颌第二恒磨牙提供一种治疗周期短、简便及微创的临床思路。Ectopic eruption of the second permanent molar is a tooth replacement disorder during adolescence.If not treated in time,it can cause hard tissue of the adjacent first molar resorption,early tooth loss,decreased chewing efficiency,and other serious malocclusions.Timely detection and treatment of ectopic eruption of the second permanent molar are of great significance in preventing malocclusions in adolescents and establishing normal occlusion relationships.However,current case reports on the ectopic eruption of the mandibular second molar are relatively rare and are mostly concentrated on surgical and orthodontic treatments,and long-term follow-up is lacking.This paper reports a case in which brass wire ligation was used to treat ectopic eruption of the mandibular second permanent molar,allowing the permanent teeth to erupt smoothly and establish a normal occlusion.The patient was observed for five years after the operation.The occlusion was stable,and the tooth root development,pulp vitality,and periodontal conditions were normal.This paper provides a clinical approach that is short in treatment duration,simple,and minimally invasive for young mandibular second permanent molars with moderate mesial inclination and partial eruption.This method is of importance in helping children establish physiological occlusion.
