Traumatic dental injuries in primary dentition present risk of sequelae in the permanent dentition. In this case report, we describe the management and long term follow-up of sequelae affecting permanent central incisor due to prior intrusive luxation and subluxation of the corresponding primary tooth. A 5-year-boy was referred for treatment, with history of fall by the age of 21 months, which caused subluxation of the primary maxillary right and left central incisors, and intrusion of the maxillary right lateral incisor. Radiographic and clinical monitoring was regularly performed. Hypoplasia and crown dilaceration of the permanent maxillary right central incisor was detected, as well as an enamel bridge between the central and lateral right incisors was diagnosed by cone bean tomography. Gingevectomy followed by the breaking of the enamel junction between the crowns of lateral and central incisors and indirect facet in composite resin were used to treat the sequelae. A precise diagnosis, involving a multidisciplinary team, contributed to the success of treatment. Case reports, follow-up studies, pediatric dentistry, tooth, deciduos, complications.
乳牙列的创伤性牙损伤会给恒牙列带来后遗症风险。在本病例报告中，我们描述了因先前相应乳牙的嵌入性脱位和亚脱位而影响恒牙中央门牙的后遗症的处理及长期随访情况。一名5岁男孩前来接受治疗，其在21个月大时有摔倒史，导致上颌左右乳中切牙亚脱位以及上颌右侧切牙嵌入。定期进行影像学和临床监测。发现恒牙上颌右中切牙发育不全和牙冠弯曲，锥形束断层扫描诊断出右侧中切牙和侧切牙之间存在釉质桥。采用牙龈切除术，随后切开侧切牙和中切牙牙冠之间的釉质连接，并使用复合树脂进行间接小平面修复来治疗后遗症。由多学科团队参与的精确诊断促成了治疗的成功。病例报告、随访研究、儿童牙科、牙齿、乳牙、并发症。
