Vector Control of Malpositioned Segment During Alveolar Distraction Osteogenesis by Using Rubber Traction
Purpose
In this study we discuss how to control and maintain the vector of the malpositioned segment, which had occurred in post-distraction, and suggested treatments.
Patients and Methods
We studied a patient who had undergone alveolar distraction osteogenesis and revealed a complication at the end of the distraction period; namely, the malpositioned segment. We treated this patient by removing the screw from the base plate and attaching a wire splint on the adjacent teeth during osseous consolidation as an anchorage to fix the malpositioned segment toward the desired direction.
Results
At the end of traction application, a normal arch shape was observed. After the completion of distraction, implants were inserted in the ideal position.
Conclusion
The described treatment strategy appears to have good potential for providing an ideal final position of the lingually or palatally inclined bone segment.
