The complications of replacement resorption following tooth injury in growing children include infrapositioning of the tooth, tilting of the adjacent teeth, and alveolar ridge deformity. Decoronation is a conservative treatment method that facilitates bone preservation. The current case report focuses on the long-term preservation of alveolar ridge dimension following decoronation in three patients. Decoronation was performed prior to occurrence of the pubertal growth spurt, and the patients' ridge width and vertical apposition were monitored for at least 4 years. Timely intervention and regular monitoring are essential for maximization of the benefits of decoronation, a simple procedure that preserves esthetics and minimizes the need for further treatments. The importance of space management for prosthetic treatment has also been highlighted. The findings of this study show that infrapositioned teeth in growing children can be treated successfully using decoronation.
儿童牙齿外伤后替换吸收的并发症包括牙齿位置过低、邻牙倾斜和牙槽嵴畸形。去冠术是一种保守的治疗方法，有利于保存骨组织。本病例报告重点关注 3 名患者在去冠术后牙槽嵴尺寸的长期保持情况。去冠术在青春期生长突增之前进行，至少监测患者的牙槽嵴宽度和垂直附着 4 年。及时干预和定期监测对于最大限度地发挥去冠术的益处至关重要，该简单手术可以保持美观并最大限度地减少进一步治疗的需要。该研究还强调了为修复治疗进行间隙管理的重要性。本研究的结果表明，生长中的牙齿位置过低可以通过去冠术成功治疗。
