Intentional replantation consists of purposefully extracting a tooth, correcting the defect and replanting it into its original socket. This case report describes how this technique was used to successfully restore an external cervical resorptive (ECR) lesion. A 22-year-old man was diagnosed with ECR of the mandibular right canine following clinical and radiographic examination. CBCT showed the lesion had been initiated distally and extended circumferentially around the root canal. The nature of the resorptive lesion meant that it was inaccessible to repair conventionally in a predictable manner. This report describes how intentional replantation was used to access and restore the lesion with minimal patient cooperation and postoperative discomfort. At an 18-month recall the tooth was clinically sound with no radiographic evidence of inflammatory or replacement root resorption. Intentional replantation should be considered a viable treatment option when ECR is inaccessible and cannot be restored using conventional techniques.
意向性再植术是指有目的地拔除牙齿，修复缺损后再将其重新植入原牙槽窝。本病例报告描述了如何运用该技术成功修复一例外部颈缘吸收（ECR）病变。一名22岁男性经临床及影像学检查后被诊断为下颌右侧尖牙ECR。锥形束计算机断层扫描（CBCT）显示病变起始于远中，并围绕根管呈环形扩展。这种吸收性病变的性质意味着常规方法难以对其进行可预测性修复。本报告描述了如何通过意向性再植术对病变进行处理和修复，同时患者的配合度及术后不适感降至最低。在18个月的复查中，该牙齿临床状况良好，影像学检查未发现炎症或替代性牙根吸收的迹象。当ECR难以处理且无法采用传统技术修复时，意向性再植术应被视为一种可行的治疗选择。
