“…Furthermore, the inadequate height of the reconstructed segments can create a large distance to the occlusal plane, which makes prosthetic rehabilitation difficult. To overcome this problem, the fibular bone can be used in a “double barrel” fashion, distracted or placed in the upper part of the neighboring mandible (Bähr et al, ; Siciliano et al, ; Wang et al, ; Shen et al, ; Chang et al, ). The large amount of bone provided by the vascularized iliac crest makes it favorable for reconstruction in both edentulous and dentate patients.…”

Regions of ilium and fibula providing clinically usable bone for mandible reconstruction: “A different approach to bone comparison”

A variety of donor sites are available for mandibular reconstruction. We present here a different way of comparing two commonly-used bone flaps. The lengths of the usable parts in a total of 241 coxal bones, 91 mandibles and 60 fibulas were measured. The mandible was measured from condyle-to-condyle and the harvestable bone length (HBL) and usable (UBL) bone lengths in fibula and ilium were also measured. The bone thickness (BT) in 60 iliac crests was measured in two parallel lines from the anterior superior iliac spine (ASIS) along the iliac crest. The mandible was 32.17 mm shorter in females than in males. The total ilium UBL was 171.12 mm in females and 178.80 mm in males. The mean HBL of the fibula was 22.6 mm shorter in females than in males. However, in some fibulas in both females and males, only 4.2% and 21.1% of the HBL respectively could be used if the ultimate goal was to insert dental implants. We found significant correlations between BT and gender in both fibula and ilium (P≤ 0.05). The ilium offers constant BT throughout the usable bone area with a similar bone length to the fibula. In contrast, the fibula showed variable bone dimensions, so not all of it is clinically usable. This should especially be considered in females when a mandibular reconstruction is planned with the goal of occlusal rehabilitation. Clin. Anat. 29:773-778, 2016. © 2016 Wiley Periodicals, Inc.

“…4,8 Moreover, additional operations may be added if the length of distractor is insufficient to restore the defects. 5 The advantage of trifocal transport distraction is the reduction of distraction period with 2 transport disks moving simultaneously. To the knowledge of the authors, there is no specific production of trifocal transport distraction device so far.…”

“…3,4 However, most related publications reported an extraoral approach that resulted in obvious facial scars. 5,6 Only few reports used a customized design and custom-made distraction device to reconstruct the original geometric outline of the mandible. 7 In this study, we report the restoration of large mandibular continuity defects through a novel intraoral customized transport distraction device and discuss the advantages and technical limitations of this technique.…”

“…Mechanical properties for the cortical bone, regenerated bone, trabecular bone, dentin, BTRP device, and symphysis were not only evaluated but also assumed from several authors [12,[23][24][25] (Table 1). A previous study from the authors reported the mechanical properties of the regenerate dog cortical bone are not only heterogeneous, but also tend to be approximately transversely isotropic at a tissue level as opposed to control cortical bone that is orthotropic [26].…”

This study compared biomechanical patterns between finite element models (FEMs) and a fresh dog mandible tested under molar and incisal physiological loads in order to clarify the effect of the bone transport distraction osteogenesis (BTDO) surgical process. Three FEMs of dog mandibles were built in order to evaluate the effects of BTDO. The first model evaluated the mandibular response under two physiological loads resembling bite processes. In the second model, a 5.0 cm bone defect was bridged with a bone transport reconstruction plate (BTRP). In the third model, new regenerated bony tissue was incorporated within the defect to mimic the surgical process without the presence of the device. Complementarily, a mandible of a male American foxhound dog was mechanically tested in the laboratory both in the presence and absence of a BTRP, and mechanical responses were measured by attaching rosettes to the bone surface of the mandible to validate the FEM predictions. The relationship between real and predicted values indicates that the stress patterns calculated using FEM are a valid predictor of the biomechanics of the BTDO procedures. The present study provides an interesting correlation between the stiffness of the device and the biomechanical response of the mandible affected for bone transport.
