BACKGROUND
The free vascularized fibula flap presents many advantages such as sufficient length of the bony segment, good vascularization, better quality of the bone, and a long vascular pedicle, but it is also associated with some disadvantages with regard to prosthetic rehabilitation because of its limited height. Improvement in bone height is necessary for ideal dental implant treatment of reconstructed mandibles.
CASE PRESENTATION
For two squamous cell carcinoma patients, mandibular bone reconstruction was performed secondarily with the peroneal flap after tumor resection. Since the bone height was insufficient at the time of implant treatment, occlusion reconstruction by dental implant was performed after vertical distraction osteogenesis.
CONCLUSIONS
Vertical distraction osteogenesis is a suitable treatment option for alveolar ridge deficiency resulting from fibula transplantation for mandibular reconstruction following tumor surgery.
背景
带血管蒂游离腓骨瓣具有许多优点，如骨段长度充足、血运良好、骨质质量较好以及血管蒂较长，但由于其高度有限，在假体修复方面也存在一些缺点。对于重建下颌骨的理想牙种植治疗而言，提高骨高度是必要的。
病例报告
对于两名鳞状细胞癌患者，在肿瘤切除后二期采用腓骨瓣进行下颌骨重建。由于种植治疗时骨高度不足，在垂直骨牵张成骨后通过牙种植进行咬合重建。
结论
垂直骨牵张成骨是肿瘤手术后腓骨移植重建下颌骨导致牙槽嵴缺损的一种合适治疗选择。
