Innovation in anterior mandibular alveolar distraction osteogenesis: introduction of a new bone-borne distraction device and first clinical results



Innovation in anterior mandibular alveolar distraction osteogenesis: introduction of a new bone-borne distraction device and first clinical results



JournalofCranio-Maxillo-FacialSurgery40(8):E503



Segmental distraction osteogenesis of the anterior mandibular alveolar process (frontblock) is a sufficient method to avoid extractions in patients with dental crowding and to decompensate retroalveolism. Up to now dental-borne devices were used, but limitate the indications for front-block distraction. A new bone-borne distraction device for mandibular alveolar front-block movement is introduced in this study. The distractor allows sufficient segmental transport without loading on the teeth. Clinical evaluations of 7 patients have been performed including the feasibility and predictability of the distraction, postoperative pain and patients' discomfort. The results indicate that this technique is a promising strategy in the correction of dental crowding, correcting the curve of Spee and to decompensate mandibular retroalveolism even in patients with impaired periodontal health and a thin mandibular symphysis.
