Impaction of permanent maxillary central incisors is a rare condition that can affect esthetics and oral function. The etiology of impaction is multifactorial and may be related to embryologic reasons, hereditary factors, mechanical obstacles, and pathologic elements, such as the presence of supernumerary teeth. The purpose of this report is to discuss the case of a 10-year-old patient who presented an impacted permanent maxillary right central incisor due to a supernumerary tooth. Surgical removal of the supernumerary tooth and orthodontic traction of the impacted central incisor by the closed eruption technique were performed. After 12 months, the permanent maxillary right central incisor was adequately positioned in the arch. The multidisciplinary treatment allowed the functional and esthetic rehabilitation to happen in a short period of time, thus reducing the patient's psychological impact caused by the lack of an anterior tooth.
恒牙上颌中切牙阻生是一种罕见的情况,会影响美观和口腔功能。阻生的病因是多因素的,可能与胚胎学原因、遗传因素、机械障碍以及病理因素有关,比如多生牙的存在。本报告的目的是讨论一名10岁患者的病例,该患者因一颗多生牙导致恒牙上颌右侧中切牙阻生。通过手术拔除了多生牙,并采用闭合萌出技术对阻生的中切牙进行正畸牵引。12个月后,恒牙上颌右侧中切牙在牙弓中获得了合适的位置。多学科治疗使得在短时间内实现了功能和美观的康复,从而减少了患者因前牙缺失所造成的心理影响。
