Abstract：
BACKGROUND: 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.
METHODS: 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.
RESULTS: 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.
CONCLUSIONS: IR combined with cyst enucleation is an effective strategy for thoroughly cleaning jaw cysts and preserving teeth involved in the cyst.

摘要：
背景：颌骨囊肿通常深深累及相邻的牙根，很难保存它们。这项回顾性研究的目的是研究有意再植（IR）策略结合囊肿摘除术在颌骨囊肿摘除过程中保留囊肿累及的牙齿的有效性。
方法：对15例颌骨囊肿和深受累牙患者进行IR和囊肿摘除治疗。所有患者在手术前接受根管治疗,除了一名在手术期间接受治疗的患者。受累的牙齿被拔掉了，并在IR和囊肿摘除前仔细清洁根表面。患者随访12-14个月,包括临床投诉在内的指标，重新种植的牙齿稳定性，和根吸收。
结果：未观察到囊肿复发，所有重新种植的牙齿都存活下来，局部牙龈状况良好，没有明显的肿胀或凹陷。影像学检查结果显示，重新种植的牙齿周围有清晰的牙周间隙。由于咬合创伤，一颗重新种植的牙齿表现出轻微的牙根吸收，但是咬合调整后吸收停止了。
结论：IR联合囊肿摘除术是彻底清洁颌骨囊肿和保留囊肿相关牙齿的有效策略。
