Abstract
Background
Lack of sufficient alveolar bone height or width is one of the most frequent problems in the dental rehabilitation of the edentulous patient.
Methods
A prospective study to evaluate the efficacy of an endosseous alveolar distractor (LEADTM) in managing residual alveolar ridge resorption was carried out. The complications related to the surgical procedure and the quantitative changes in the regenerate over a 6 month period following distraction were studied in 13 cases with alveolar ridge atrophy.
Result
Desired ridge augmentation was achieved in 11 cases. In 2 cases the distraction failed. Some unusual complications were encountered.
Conclusion
The LEAD™ alveolar distractor produces consistent augmentation of the alveolar bone but is confronted with stability issues.
Keywords: Distraction osteogenesis, Alveolar augmentation, LEAD™
