Where difficult anatomical conditions are involved, distraction osteogenesis using extraoral devices is frequently indispensable. Multidirectional systems offer the advantage of convenient vector adjustment during the distraction process. Moreover, greater distraction lengths are achievable, compared with simple intraoral systems.
The 3DX external mandibular distractor from KLS Martin has been developed for treating mandibular hypoplasias and asymmetries. Besides, it is used for correcting posttraumatic defects requiring gradual, three-dimensional bone lengthening. The distractor is fully adjustable in all three planes.
"Flowing" bone movements are possible also with fixed distractor because the chosen vector can be adjusted or modified at any time. A new carbon-fiber consolidation bar reduces the distractor to a minimum during the consolidation phase.
The external monodirectional distractor acc. to Molina is intended for osteogenesis on the ascending ramus of the mandible. The device impresses by its simple and stable design. It is available in three different sizes: for infants (gold-colored), for children and adolescents (blue), and for adults (gray).
