The end result is that the crest of the mandibular posterior ridge becomes located inferiorly and m to it's original position. This results in a shear force which is the weakest component of bone. This will occur even if a nerve repositioning procedure is performed. A much better concept involves using distraction osteogenesis to move the mandibular posterior alveolar segment superiorly and laterally in a vector which will align the occlusal forces of the maxillary and mandibular molar teeth. This will result in a compressive force on the bone instead of a shear force.
Bone is strongest during compression.
Sometimes, due to miscellaneous factors, an implant will achieve complete bone integration and yet not be in the correct location for esthetics or loading. Distraction osteogenesis can be used to relocate the alveolar segment, including the misaligned implants, to a new location. There are a couple of ways to achieve this. First, the segment must be disease free and stable prior to movement. A model should be made to determine the vector component required to move the alveolar segment into the correct location.
