“…Distraction osteogenesis for maxillo-mandibular reconstructive need can be classified into: monofocal distraction osteogenesis and TDO [3]. TDO can be achieved by incremental movement of one (bifocal distraction), two (trifocal distraction) or three (quadrifocal distraction) viable bone segments (transport disks) across a defect [4] (Fig. 2).…”

“…Costantino et al were the first to report bifocal distraction (TDO) of the mandible by using an external custom made distraction device to regenerate a segmental defect of 40-mm. Since then there have been rapid advancements in the field of TDO, which has now become an important tool for the reconstruction of composite defects [4].…”

“…Segmental defects may be a result of ablative surgery for odontogenic tumors, surgical removal of cancers, chronic bone infections, blast injuries, gunshot wounds, etc. [4]. When indicated, TDO has its own advantages over high failure rates in non-vascularized bone grafts and high complication rates of highly demanding techniques of vascularized bone grafts [8].…”

Reconstruction of the facial skeleton remains a herculean task for a reconstructive surgeon, even with the availability of ample reconstructive options. Transport distraction osteogenesis is a novel reconstructive modality in the armamentarium of a maxillofacial reconstructive surgeon with obvious advantages of osteogenesis and histogenesis from the residual host tissues after tumor ablative surgeries or trauma and also, precludes donor site morbidity. This paper reviews the current concepts, principles involved and applications of transport distraction osteogenesis in maxillomandibular reconstruction.

“…Although many places could be considered for its placement, the device was specifically developed for straight bone transport at the body of the mandible, thus the ramus and the symphysis were not considered as the places for distraction. In addition, the lower placement of the device is related with its double function, which provides both the active distraction and the main structural support [44].…”

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.
