Vertical distraction osteogenesis can extend not only to hard tissues but also to soft tissues. There is a tendency to cause progressive lingual inclination of the distracted segment. This study describes a method for preventing the lingual inclination of the transport segment in patients with vertical distraction osteogenesis in the anterior region of the mandible and reports the results of long-term follow-up. The subjects included 5 patients who had severely atrophic ridges in the anterior mandible. In all cases, a part of the mental protuberance was scraped out, and the distractor was placed suitably in a labioinclination beforehand. Therefore, the transport segments did not lean to the lingual side and had long-term stability.
垂直牵引成骨不仅可以延伸到硬组织，还可以延伸到软组织。存在导致分散段渐进性舌倾的趋势。本研究描述了一种预防下颌前区垂直牵引成骨患者中运输段舌倾的方法，并报告了长期随访结果。研究对象包括 5 名下颌前区严重萎缩牙槽嵴的患者。在所有情况下，都刮除了部分颏隆突，并且事先在唇倾方向适当放置了牵开器。因此，运输段没有向舌侧倾斜，并且具有长期稳定性。
