Abstract:

Objective: To report a case of segmental vertical distraction osteogenesis and dental implantation after fibula reconstruction of segmental defect of mandible in the 920th Hospital of Joint Logistics Support Force, PLA in August 2020. Methods: In stageⅠ, the mandibular fibula flap was cut horizontally and vertically and a built-in distractor was implanted. According to the principle of distraction osteogenesis and the bone height requirements for implantation, the fibula segmental vertical distraction treatment was completed; in stageⅡ, the distractor was removed and dental implants were installed. Results: According to the imaging examination and intraoperative findings, good bone height was obtained through fibula segmental vertical distraction osteogenesis, and the initial stability of the implant was good. Conclusion: The segmental vertical distraction osteogenesis of the fibular flap can be used as an effective technique to increase the bone height after the fibular flap reconstruction.

摘要：

目的：报道1例于2020年8月就诊于中国人民解放军联勤保障部队第九二〇医院下颌骨节段性缺损，腓骨修复重建后行分段垂直牵张成骨及牙种植的病例资料。方法：Ⅰ期手术为水平及垂直截开下颌的腓骨瓣，植入内置牵张器，依据牵张成骨原则及种植所需高度完成腓骨分段垂直牵张治疗；Ⅱ期手术为拆除牵张器并植入种植牙。方法：根据影像学检查及术中所见，腓骨分段垂直牵张成骨良好，能够得到良好的骨高度，种植体初期稳定性良好。结论：腓骨瓣分段垂直牵张成骨可作为腓骨瓣修复后提升其骨高度的有效技术。
