Abstract

Objective : This is to report the effectiveness of intraoral distraction osteogenesis, iliac bone graft for alveolar augmentation in the extremely atrophied alveolar defects after infected allobone grafted area. Subjects and Methods : Anterior segmental osteotomy was performed and the trans-oral alveolar distractors (Martin, Germany) were applied in patient with the severe acquired anterior mandibular and mandibular defect after ameloblastoma enucleation. Iliac bone grafts were performed in defect sites and distraction osteogenesis were treated. After latent period for 1 week, the osteomized alveolar segments were distracted by 0.75 mm a day (0.25 mm/1 turn) for 10 days The consolidation period was about 12 weeks. Thereafter, 2 titanium threaded implants were simultaneously installed with removal of distractor. For oral rehabilitiation, The implants were installed in maxilla, mandible. It was tested with clinically and radiographically. Results : Amounts of acquired alveolar bone were 10 mm with the increased width of the ridge crests and soft tissue expansion. Dental implants installated on the augmented alveolar ridges in 12 weeks after distraction were confirmed as in good osseointegration and in good function without any complications. Conclusion : Intraoral distraction osteogenesis can be a good option for alveolar ridge augmentation of the severely atrophied ridges and soft-tissue defects.
