Abstract

A 63-year-old man underwent segmental mandibulectomy for ameloblastoma, followed by fibula free-flap reconstruction. As the bone volume was inadequate, guided bone regeneration (GBR) was performed using iliac particulate cancellous bone and marrow, titanium mesh, and tenting screws. After consolidation, 4 implants were placed, and restoration was completed with a computer-aided design and computer-aided manufacturing titanium bar and LOCATOR-retained overdenture. This staged approach ensured stable implant placement and successful rehabilitation. At 1 year postoperatively, the patient’s appearance and masticatory function had improved significantly, with no peri-implant or prosthetic complication. The combined application of GBR and a 2-stage protocol after fibula flap surgery enables the predictable achievement of functional reconstruction.

以腓骨瓣为基础的下颌骨重建，钛网和帐篷螺钉引导骨再生后种植支撑覆盖义齿的放置：一份临床报告。

一位63岁的男性接受了下颌骨成釉细胞瘤的节段性切除术，随后腓骨自由皮瓣重建。由于骨容量不足，采用髂骨颗粒松质骨和骨髓，钛网和帐篷螺钉进行引导骨再生（GBR）。巩固后放置4颗种植体，采用计算机辅助设计和计算机辅助制造钛棒和locator -固位覆盖义齿完成修复。这种分阶段的方法确保了稳定的种植体放置和成功的康复。术后1年，患者的外观和咀嚼功能明显改善，无种植体周围或假体并发症。联合应用GBR和腓骨皮瓣手术后的两阶段方案可以实现可预测的功能重建。
