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.
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.
At the end of traction application, a normal arch shape was observed. After the completion of distraction, implants were inserted in the ideal position.
The described treatment strategy appears to have good potential for providing an ideal final position of the lingually or palatally inclined bone segment.
在本研究中,我们讨论了如何控制和维持在牵张后出现的错位节段的载体,并提出了治疗方法。
我们研究了一名接受牙槽骨牵张成骨术的患者,该患者在牵张期结束时出现了并发症,即错位节段。我们通过在骨巩固期间从基板上取下螺钉并在相邻牙齿上附着钢丝夹板作为锚固,将错位节段朝着期望的方向固定,对该患者进行了治疗。
在牵引施加结束时,观察到正常的牙弓形状。牵张完成后,种植体被植入理想位置。
所描述的治疗策略似乎具有很大潜力,可为舌侧或腭侧倾斜骨段提供理想的最终位置。
