Internal Distraction Osteogenesis With a Unidirectional Device for Reconstruction of Mandibular Segmental Defects

Biomechanical Configurations of Mandibular Transport Distraction Osteogenesis Devices

“…The relationship with the cutaneous tissues MBT devices can be internal, 9,[14][15][16][17][18][19][20][21]24,25,27,31,42 if the bulk of the device is buried beneath the cutaneous tissues, or external, 1,8,22,23,26,[28][29][30]32,[43][44][45] if the device uses transcutaneous pins to attach to the bone (Fig. 4).…”

“…7 Bone transport distraction osteogenesis is used for the reconstruction of segmental defects by means of the incremental movement of one (bifocal distraction) (Fig. 2B1), [14][15][16][17][18][19][20][21][22][23][24][25][26][27] two (trifocal distraction) (Fig. 2B2), 9,[28][29][30][31][32] or three (quadrifocal distraction) (Fig.…”

“Transport Distraction Osteogenesis for Reconstruction of Mandibular Defects”: Our Experience

“…In transport osteogenesis the callus formed during gradual distraction has all the characteristics of an ideal transplant material that requires no mechanical stimulation. The main stimulator of bone growth was found to be tension on the callus while the proximal surfaces are mobilized [3].…”

“…Distraction osteogenesis is a promising treatment for reconstructing the defect of the mandible. It shares all the advantages of autogenous bone graft with minimal donor site morbidity, and by the use of indigenous distractors this technique of reconstruction of the mandible is reliable yet affordable [3,7,18,19].…”

“…Most recently, another treatment option has been described in the literature, ''distraction osteogenesis'' Although distraction osteogenesis has been widely used in long bones for several decades; it is not until the 1990s that this technique became a common method in mandibular lengthening. By means of this procedure new bone is created after, osteotomy followed by gradual separation of bony fragments [3]. First described by Codivilla in 1905 [4], but was popularized and studied extensively through the work of Professor Gavrill A. Ilizarov, beginning in 1951 [4].…”
