Abstract
This study aimed to assess the efficacy of sandwitch osteotomy technique in reaching the dimensional requirements of preimplant bone augmentation in the case of the atrophic posterior mandible. Sandwich osteotomy was performed on eight patients having atrophy in the posterior mandible with an estimated bone height of at least 4 mm above mandibular canal in addition to a transverse width of at least 3 mm. Chin graft harvesting was done and the corticocancellous block was fixed at the recipient site using miniplates and screws. The study concluded that sandwich technique of ridge augmentation was found to be a reliable technique in increasing vertical dimension of alveolar ridge.
