Intentional replantation (IR) is a reliable and predictable treatment option for cases with failed non-surgical root canal treatment. The success of IR is found to be 52-95%. The current case is of 35years old female who presented with severe pain and swelling in lower right first mandibular molar with previously initiated non-surgical root canal treatment that resulted in instrument separation in mesio-buccal canal. Periapical radiograph showed rarefactions at furcation area, mesial and distal root apices. It was decided to complete the non-surgical root canal treatment followed by intentional replantation and retrograde filling with MTA. The tooth was found to be asymptomatic after two years follow up and periapical radiographs depicted complete healing. Intentional replantation with careful case selection is a successful, easy and reliable treatment option for hopeless cases. Atraumatic extraction, minimum extra-alveolar time and aseptic techniques during the procedure are the key factors for success of the procedure.
对于非手术根管治疗失败的病例， 意向性再植术（IR）是一种可靠且可预测的治疗选择。IR 的成功率为 52-95%。本病例为 35 岁女性，右下第一下颌磨牙出现严重疼痛和肿胀，此前已进行非手术根管治疗，但导致近中颊根管的器械分离。根尖片显示分叉区、近远中根尖有稀疏区。决定完成非手术根管治疗，然后进行意向性再植和 MTA 逆行填充。两年后随访时，牙齿无症状，根尖片显示完全愈合。对于无望的病例， 意向性再植术是一种成功、简单且可靠的治疗选择。仔细选择病例、 无创伤拔牙、 尽量缩短牙槽外暴露时间和手术过程中的无菌技术是手术成功的关键因素。
