Alveolar Ridge Augmentation using the Allograft Bone Shell Technique

The loss of teeth, whether it is from trauma or pathology, is accompanied by a concomitant loss of the surrounding alveolar bone. Khoury introduced a new method for grafting ridge defects in 2007. This technique involved using thin cortical plates harvested from the ramus, and in a 'sandwich' type manner, interposed these bone plates with cancellous bone harvested from the same site. Although this has shown success, the technique suffers from similar disadvantages of most harvesting techniques, i.e. a need for a second surgical site, and donor site morbidity. In this case presentation, we report the use of an allograft bone plate in a similar manner as was previously described by Khoury, to reconstruction lost alveolar bone in order to facilitate the correct three dimensional (3D) placement of dental implants.
