    Abstract:
    The use of the vascularized fibula graft has already been established for reconstruction of the mandible following ablative surgery. In order to reconstruct the vertical height of the alveolar process and improve implant position as well as angulation, some therapeutic options are available, including primary use of the fibula as a double-barrel graft and vertical distraction as well as later augmentation with avascular bone grafts. We analyzed the anatomic and morphologic features in 40 fibula bones of 20 cadavers and provided the mean cortical thickness of different transplant sites. Furthermore, we investigated the primary implant stability of dental implants inserted monocortically in harvested fibula segments using established biomechanical methods as well as Periotest(®). The minimal bone height of the clinically relevant segments of the fibula transplant measured 9.06 ± 0.45 mm, which was assessed in the most distal part. In contrast, a maximal total bone height of 15.46 ± 0.78 was observed in the middle segment of the fibula bone. We assessed sufficient primary stability in all inserted implants as well as a reliable relative micro-movement of the implants in the fibula bone. Fibula graft as a single-barrel graft alone may provide through monocortical implant insertion a further refinement of the method to fit complex requirements and shorten prolonged therapeutic procedures. Monocortical implant insertion in the fibula graft would simplify oral rehabilitation after ablative surgery of the jaw and reduce costs as well as therapy period.
