Vector control of malpositioned segment during alveolar distraction osteogenesis by using rubber traction.

摘要

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.
