Jaw cysts often deeply involve adjacent tooth roots, making it difficult to preserve them. The purpose of this retrospective study was to investigate the effectiveness of an intentional replantation (IR) strategy combined with cyst enucleation in preserving cyst-involved teeth during jaw cyst removal.
Fifteen patients with jaw cysts and deeply involved teeth were treated with IR and cyst enucleation. All patients received root canal therapy prior to surgery, except for one patient who received it during surgery. The involved teeth were extracted, and the root surface was carefully cleaned before IR and cyst enucleation. Patients were followed up for 12-14 months, with indicators including clinical complaints, replanted tooth stability, and root resorption.
No cyst recurrence was observed, and all replanted teeth survived with good local gingival condition and no marked swelling or recession. Radiographic findings showed clear periodontal space surrounding the replanted teeth. One replanted tooth exhibited slight root resorption due to occlusal trauma, but the resorption ceased after occlusal adjustment.
IR combined with cyst enucleation is an effective strategy for thoroughly cleaning jaw cysts and preserving teeth involved in the cyst.
颌骨囊肿常深及邻牙牙根，难以保留。本回顾性研究旨在探讨在颌骨囊肿切除术中，采用囊肿剜除联合意向再植术（IR）保留囊肿累及牙的有效性。
15 例颌骨囊肿伴深在累及牙的患者接受 IR 和囊肿剜除术治疗。所有患者术前均行根管治疗，1 例患者术中接受根管治疗。术中取出受累牙，IR 和囊肿剜除前仔细清洁牙根表面。患者随访 12-14 个月，观察指标包括临床症状、再植牙稳定性和牙根吸收情况。
无囊肿复发，所有再植牙均存活，局部牙龈状况良好，无明显肿胀或退缩。影像学检查显示牙周间隙清晰，围绕再植牙。1 颗再植牙因咬合创伤出现轻微牙根吸收，但经咬合调整后吸收停止。
IR 联合囊肿剜除术是一种彻底清除颌骨囊肿并保留囊肿累及牙的有效策略。
