(A) Panoramic radiography showing the placement of 2 unidirectional internal distraction osteogenesis (DO) devices, with transport disc segments designed from the posterior maxillary sites to the anterior midpoint; (B) intraoperative view during the second surgical time. Both distractors devices placed intraorally at the end of the distraction period; (C) intraoperative view, bone formation after DO; (D) endosseous dental implants placed in distracted bone segments.
