Mandible Distraction
The different anatomical forms of mandibular microsomias and asymmetries frequently make high demands on the variability and adaptability of the distractors used. Prefabricated distractor models are sometimes too static and therefore cannot meet the requirements of specific clinical tasks. The Zurich mandibular distractors are suitable for distraction of the ascending mandibular ramus as well as of the mandibular body in infants and young adults in case of congenital or acquired mandibular defects and hypoplasia.
The Zurich II concept is suitable for similar indications but takes a completely different path: it is totally based on a modular principle, breaking down intraoral distractors into their basic components. All system components can be easily and rapidly combined with each other to create a perfect whole.
Additionally, transport distraction represents an interesting therapeutic option for patients with mandibular continuity defects as a result of trauma or resection or defects from malignant tumors after radiation and hyperbaric oxygen therapy.
