A Simple Solution for Vector Control in Vertical Alveolar Distraction Osteogenesis
One of the important and frequent complications in alveolar distraction osteogenesis is vectorial change of the transport segment. This report presents a simple solution for vector angulation control by placing intermaxillary fixation screws intraoperatively. Advantages of the technique are also discussed.
Location of the screws and wire connection in relation to the distraction device on the model.
A patient treated with vertical alveolar distraction in the posterior mandible. (a) Intermaxillary fixation screws and wire used simultaneously to prevent rod tipping. (b) Proper orientation of the transport segment at the end of consolidation. (c) Excellent bony healing for implant insertion observed at re-entry. (d) Implant inserted as desired.
