Material and Methods
The protocol and guidelines for this study were approved by the Medical Ethical Committee of the Academic Medical Center of the University of Amsterdam, the Netherlands. The study was conducted between 2001 and 2003 at the Department of Oral and Maxillofacial Surgery, Academic Medical Center of the University of Amsterdam, The Netherlands. The study group consisted of 10 patients (all female) aged 44.2 ± 14.3 years (range 20 to 46 years). Five mandibular and 5 maxillary distraction procedures
Results
The distraction process produced an alveolar ridge improvement in all patients. No infections, dehiscence, or alveolar pedicle lesions were seen. At the end of the active distraction, 4 patients experienced some pain, and the rate of distraction was changed from 2 × 0.5 mm to 4 × 0.25 mm, after which the pain resolved. The activation was ended after 1 week and the vertical gain was 7 mm (7 × 1 mm) in all patients. The regeneration of soft tissues was excellent in all patients and the alveolar
Discussion
Alveolar distraction osteogenesis has become one of the techniques to augment the alveolar ridge vertically in deficient alveolar bone for later endosseous implant placement. The results of our study demonstrated that the process of alveolar distraction osteogenesis has a strong influence on the vascular response, especially during the phases of active distraction. The distraction process produced a vertical alveolar ridge improvement in all patients and reconstructive implant surgery could be
