• The distraction device is incorporated in the basal segment, as well as in the transport segment, of the bone with parallel plains in a parallel level to guarantee the three-dimensional vector. Therefore, the distraction can be carried out by a predictable vector. Both segments are stabili zed by the incorporated plains, which are connected by a cardanic. (Bone substance 8mm of vertical dimension above the alveolus nerve)

• The transport segment of the distraction device is incorporated in the horizontal osteotomy and the basal segment of the distraction device is incorporated in a parallel way in the basal bone rectangular to the distraction level. (Basal bone substance4 – 8 mm above alveolus nerve)

• The transport segment of the distraction device, as well as the basal segment, is incorporated in the horizontal osteotomy, provided the osteotomy is made right below the cortical plain of the alveolar crest. It is, therefore, possible to guarantee a vector stabilized distraction even with a minimal bone height. (Basal bone substance 4mm; Cawood class 7 and 8)


• If there is only a minimal remainder of the alveolar crest left, it is possible to place the basal part below the level of the canalis alveolaris inferior.
