The management of crown-root fractures poses significant uncertainty and involves meticulous evaluation of the tooth and supporting structures. The uncertain prognosis associated with crown-root fractures necessitates periodic evaluation.
A 15-year-old female presenting with crown-root fracture of the permanent left maxillary incisors was treated by surgical extrusion with rotation for the central incisor, while the lateral incisor was coronally extruded by 2 mm. Root canal treatment was performed after the extrusion procedure, which was followed by full coverage restoration. At the 12-month recall, the teeth showed satisfactory gingival and periodontal health, with well-maintained esthetics.
Although relatively invasive, surgical extrusion can be a more conservative treatment option for the management of permanent teeth with crown-root fractures.
Marginal bone loss and gingival recession, which are usual complications of intentional replantation, were not significant findings at the 12-month follow-up.

冠根折的治疗存在很大的不确定性，需要对牙齿及其支持结构进行细致评估。冠根折相关的预后不确定，因此需要定期评估。
一名15岁女性，因恒牙左上中切牙冠根折就诊，对中切牙采用手术旋转挤压复位治疗，侧切牙向冠方挤压2毫米。挤压术后进行根管治疗，随后进行全冠修复。在12个月的复查时，牙齿的牙龈和牙周健康状况良好，美观得以维持。
尽管手术挤压复位相对具有侵入性，但对于冠根折的恒牙治疗而言，它可能是一种更为保守的治疗选择。
在12个月的随访中，未发现边缘骨丧失和牙龈退缩等常见的有意再植并发症。
