An alternative distraction osteogenesis method for atrophic posterior mandible: Case report

Abstract

Vertical lenghtening by distraction osteogenesis has been widely used for reconstruction of dentoalveolar defects. However if bone height between the alveolar crest and the anatomical structures is insufficient, performing an appropriate osteotomy and placement of distractors in desired position is impossible. In the presented case sagittal lengthening of the posterior mandible with distraction osteogenesis was achieved. After horizontal augmentation of the crest by intraoral cortical bone graft, 2 implants were inserted to the distraction area.
