Orthodontic space closure is a treatment alternative when a maxillary central incisor is missing. The objective of this report was to present an unusual treatment in which a right maxillary central incisor was moved through the midpalatal suture to replace the absent contralateral tooth. The biologic aspects and clinical appearance of the recontoured lateral and central incisors were analyzed. The position of the examined teeth and the appearance of the surrounding soft tissues were satisfactory; however, the upper midline frenulum deviated to the left. The incisor was successfully moved with no obvious detrimental effects as observed on the final radiographs. In the radiographic and tomographic examinations, the midline suture seemed to have followed the tooth movement. The patient expressed satisfaction with the results. It was concluded that orthodontic movement of the central incisor to replace a missing contralateral tooth is a valid treatment option, and the achievement of an esthetic result requires an interdisciplinary approach, including restorative dentistry and periodontics.
正畸牙间隙关闭是上颌中切牙缺失的一种治疗选择。本报告的目的是介绍一种不常见的治疗方法，即将右侧上颌中切牙通过腭中缝移动以替代缺失的对侧牙齿。分析了重新成形的侧切牙和中切牙的生物学方面和临床外观。检查牙齿的位置和周围软组织的外观令人满意，但上中切牙系带偏向左侧。中切牙成功移动，最终 X 光片未见明显不良影响。在放射和断层扫描检查中，中缝似乎随着牙齿的移动而移动。患者对结果表示满意。结论：正畸移动中切牙以替代缺失的对侧牙齿是一种有效的治疗选择，而获得美观效果需要多学科方法，包括修复牙科和牙周病学。
