With the introduction of distraction osteogenesis in oral and maxillofacial surgery in the mid 1990s, especially for the treatment of congenital malformations, there was initially a rapid development in the vertical alveolar distraction procedures based on the TRACK (Tissue Regeneration by Alveolar Callus distraction) distractors, which were seen as a preimplantologic grafting procedure. Because the treatment requires high surgical skill and intensive patient care in the postoperative follow-up, the procedure is now used selectively for particular indications. With precise indications, especially in the case of multiple previous surgeries, this method is superior to the other augmentation techniques in terms of complications and the possible vertical defect height reconstruction
