The fibula is the preferred bone flap for mandibular reconstructions due to its many advantages, including the possibility to insert dental implants. All patients who received a mandibular reconstruction with a vascularized free fibula flap at the Uppsala University Hospital between 2009 and 2019 were retrospectively examined regarding the proportion of implant insertion and factors that affected implant outcome. Forty-one patients had 42 fibula flap reconstructions. Eleven patients (27%) received dental implants and 8 (20%) completed dental rehabilitation. Patient death and cancer recurrence were the main reasons for not receiving implants. The survival rates of implants placed in irradiated and nonirradiated fibulas were 15% and 76%, respectively. Less than 20% of reconstructed patients received an implant-supported prosthesis. Implants placed in an irradiated fibula should be considered at high risk for implant loss.
腓骨因其诸多优势，如可植入牙种植体，成为下颌骨重建的首选骨瓣。我们回顾性分析了 2009 年至 2019 年在乌普萨拉大学医院接受游离腓骨血管化重建的所有患者，研究了种植体植入的比例以及影响种植体结果的因素。41 例患者行 42 例腓骨瓣重建，11 例（27%）患者接受牙种植体，8 例（20%）完成牙修复。患者死亡和癌症复发是未植入种植体的主要原因。在接受放疗和未接受放疗的腓骨中，种植体的存活率分别为 15%和 76%。不到 20%的重建患者接受了种植体支持的修复体。在接受放疗的腓骨中植入种植体，应考虑其种植体丢失的风险较高。
