摘要:

全脱出牙延期再植后易发生替代性吸收,对于儿童患者而言,发生替代性吸收后,会引起牙槽骨发育障碍及邻牙倾斜,然而临床上并无有效的方法阻止替代性吸收的进展。近年来,截冠术逐渐成为国际牙外伤协会推荐的治疗替代性吸收的首选。本文采用截冠术治疗1例儿童患者全脱出牙延期再植后替代性吸收,并术后随访观察4年,对截冠术治疗延期再植后替代性吸收的过程及远期疗效进行了报道。

Abstract:

Replacement resorption is the most frequent complication after delayed replantation of avulsed teeth. The resorption can interfere with the development of the alveolar ridge and lead to tilt of the adjacent teeth in growing patients. However, there is no means of arresting or reversing the process. Recently decoronation is recommended by International Assocaition of Dental Traumatology as the optimal choice to manage it. This paper demonstrates the procedure and effecti-veness of the decoronation by literature review and a case report with 4-year follow-up.

Key words: avulsed teeth, delayed replantation, replacement resorption, decoronation
