Distraction osteogenesis with subperiosteal devices in edentulous mandibles

Complication rates and associated factors in alveolar distraction osteogenesis: a comprehensive review

“…Complications were only sporadically reported in the literature. Problems and difficulties encountered in DO were mainly reported as case reports or case series 14 It has also been suggested that alveolar DO may be more prone to minor complications than the inlay procedure 2 and should not be the first choice treatment for correcting vertical alveolar bone height 52 . The present review was designed to estimate the severity and frequency of complications that might occur during DO, as well as the risk factors associated with them.…”

“…Several reports suggest that distraction may not be a good option if the bone height above the inferior alveolar nerve will be less than 6-8 mm 36,47 or if the transport segment will be less than 4-5 mm high 33,55,58 , especially if the case is otherwise complex. Three cases of basal bone fracture and three cases of fracture of the transport segment were reported in a series of nine patients with minimum bone height in the canine region of 5 mm (mean 7.9 mm) 14 . A greater occurrence of mandibular fractures (17%) during the consolidation period should be considered when the residual bone height is less than 10 mm 52 .…”

“…It has been suggested that the use of distraction for vertical augmentation has no advantages in comparison with conventional methods 14 , and that it has disadvantages that have to be considered carefully 68 . A few articles have focused on the problems and complications that can occur during treatment 15,17,22,24,28,63,69,72,73 .…”

Evaluation of Vertical Bone Gain Following Alveolar Distraction Osteogenesis in the Anterior Edentulous Mandible: A Clinical Study

“…The ADO is a method that allows augmentation of alveolar ridge height with new bone formation as well as obtaining a significant increase in the surrounding soft tissues, offering a predictable result, with low morbidity and infection rates and a significantly shorter waiting period for rehabilitation with implants and prosthesis. Distraction osteogenesis can be achieved by extraosseous [7] or intraosseous [8,9] devices. Extraosseous devices for vertical distraction of the mandible are usually placed subperiosteally [7].…”
