In young patients, premature tooth loss in the anterior maxilla after trauma is challenging for the patient and the dental professional, with serious implications from aesthetic and functional points of view, as well as from a craniofacial growth aspect perspective. Premolars autotransplanted into the maxillary anterior region have been shown to be a biological alternative in this situation. This report describes the clinical management of a case of premature loss of a maxillary central incisor after traumatic injury. A mandibular premolar at the stage of initial root development was transplanted into the alveolar socket of the lost incisor. After 18 years, the transplanted tooth remained responsive to pulp sensibility tests and the periradicular bone and soft tissues were within normal limits. Autotransplantation of premolar teeth into the maxilla could be considered an excellent treatment choice with many biological advantages over implants or fixed dentures as long as proper case selection is followed.
在年轻患者中，外伤后上颌前部牙齿过早缺失对患者和牙科专业人员来说都是一项具有挑战性的问题，从美学、功能以及颅面生长的角度来看都有严重影响。已证明在前述情况下，将前磨牙自体移植到上颌前部区域是一种生物学替代方法。本报告描述了一例外伤后上颌中切牙过早缺失病例的临床处理情况。一颗处于牙根初始发育阶段的下颌前磨牙被移植到缺失切牙的牙槽窝内。18年后，移植牙对牙髓敏感性测试仍有反应，根尖周骨和软组织均在正常范围内。只要遵循恰当的病例选择，将前磨牙自体移植到上颌可被视为一种优于种植牙或固定义齿的极佳治疗选择，具有诸多生物学优势。
