Alveolar distraction in post traumatic mandibular atrophy : report of two cases

The main indication to use vertical alveolar distraction is post-traumatic mandibular atrophy. This technique allows to obtain an adequate bone volume for insertion of osseointagrated implants. The authors present in this article two patients cases in whom alveolar vertical distraction was applied to atrophy post-traumatic, using endoral twin track distraction. In both cases it was prepared a stereolithography model to mimic the box of the bone to be distracted, to align the preoperative distractor and to obtain the more effective carrier. At the distractive stage followed the implant prosthesis stage which was designed to rehabilitate the previously atrophic bone area. In both patients it has been possible to insert the planned number of implants
