title: Reconstruction of the severely resorbed mandible prior to vestibuloplasty or placement of endosseous implants. A 2 to 5 year follow-up.
abstract: Ninety-two patients underwent augmentation of the severely resorbed mandible using corticocancellous bone grafts in the symphysis and a mixture of autogenous cancellous bone chips and hydroxylapatite particles in the posterior area. This study, extending from 2 to 5 years, shows that predictable and stable results were achieved. The average loss of height measured at 3 reference points was approximately 20%. Slight sensory disturbance was present in 19 patients (23%). Benefits derived from augmentation of the atrophic mandible include: improvement of facial form due to the renewed support of the collapsed circumoral muscles, a decrease in the intermaxillary distance, and restoration of mandibular bone bulk that will accommodate endosseous implants of maximum size.
