目的：无腓骨骨筋膜皮瓣移植已成为口面部综合缺损重建的常规手术。除了长度之外，无腓骨瓣的主要优点还包括腓骨的三角形直径，这通常允许放置牙种植体。 患者和方法：在一项前瞻性研究中，对 1999 年至 2001 年间连续接受游离腓骨移植的 16 名患者和总共 51 个牙种植体进行了检查。所有种植体均在骨移植后二次植入，并在 3 个月的埋入式愈合后加载。观察期平均延长2.5年。种植体的成功通过临床、放射学和共振频率分析来控制。结果：位于腓骨移植物和下颌骨交界处的一颗种植体在愈合期间由于裂开和局部感染而丢失。在另外两名患者中，由于软组织状况不利，一颗植入物必须保持不暴露状态，作为“睡眠者”。经过1400天的观察期，Kaplan-Meier分析计算出的成功率为96.1%。共振频率分析（ISQ 值）揭示了与换能器单元的方向（前庭-口/近-远；vo/md）相关的显着差异（P
Objectives: The transfer of the osseofasciocutaneus fibula-free flap has become a routine procedure in the reconstruction of comprehensive orofacial defects. Besides its length, major advantages of the fibula-free flap include the trigonal diameter of the fibular bone, which usually allows the placement of dental implants.Patients and methods: In a prospective study, 16 consecutive patients who received free fibula grafts and in total 51 dental implants between 1999 and 2001 were examined. All implants were inserted secondary after bone grafting and loaded after 3 months of submerged healing. The observation period extended 2.5 years on average. The implant success was controlled clinically, radiographically and by resonance frequency analysis.Results: One implant that was located at the interface between the fibula graft and the mandible was lost due to dehiscence and local infection during the healing period. In two other patients, one implant had to remain unexposed as 'sleeper' due to an unfavourable soft tissue situation. The success rate calculated by Kaplan-Meier analysis was 96.1% after an observation period of 1400 days. Resonance frequency analysis (ISQ-values) revealed significant differences related to the orientation (vestibulo-oral/mesio-distal; vo/md) of the transducer unit (P
