Clinical, radiographic, and histologic evaluation of localized ridge augmentation using a mandibular bone block

This clinical case report presents a new technique for reconstructing the vertical and horizontal dimensions of the alveolar ridge using a mandibular bone block at sites planned for single implants. Augmentation was eased with the use of a mandibular bone block, which was shaped after placement with a round bur to passively fit the dimensions of the defect, at the recipient site. After treatment, approximately 7 mm of horizontal and 3 mm of vertical augmentation were gained. Histologic observation showed that the grafted bone was well integrated with the original bone. The volume of tissue gained was sufficient for placing an implant in an optimal position. The gain in the vertical and horizontal dimensions allowed an esthetic result with a single-tooth crown.
