The left mandibular premolars were extracted from five adult dogs. After twelve weeks, a box-shaped osteotomy of the alveolar bone was carried out and two 10 mm implants were placed 5 mm into the transport alveolar segment, leaving 5 mm exposed. The alveolar bone was vertically augmented 5 mm by screwing the implants. After distraction, the implants were left to integrate into the bone. Histological and radiographical evaluations showed the lifting of the transport segment and the development of new bone in the distraction area. Although integration of implants within both the transport segment and the regenerated bone was observed, two of the ten implants failed and partial bone resorption of the transport segment was noted.
从五只成年犬中拔除左侧下颌前磨牙。十二周后，对牙槽骨进行盒状截骨术，并将两枚10毫米种植体植入运输牙槽段5毫米深处，使其外露5毫米。通过拧入种植体将牙槽骨垂直增高5毫米。牵张后，让种植体与骨整合。组织学和影像学评估显示运输段抬高以及牵张区域有新骨形成。尽管观察到种植体在运输段和再生骨内均实现了整合，但十枚种植体中有两枚失败，且运输段出现了部分骨吸收。
