Alveolar ridge augmentation with autogenous mental block harvested using ultrasonic bone surgery (USBS) and platelet rich plasma: a case report.

Predictable reconstruction of alveolar ridge defects can be obtained by using autogenous bone block. Ultrasonic bone surgery (USBS) is a fast, precise, and simple technique for block graft harvesting. It allows for a clean surgical field with no risk of injury to surrounding neurovascular structures. This article describes a case of horizontal alveolar ridge defect augmented with mental bone block harvested using USBS. The defect was overcorrected using bovine derived xenograft and platelet rich plasma, which is an autologous source of growth factors that helps in early graft consolidation. Platelet poor plasma (PPP) membrane was used for graft containment. After six months, on exposure, it was observed that the block graft was integrated with the alveolar ridge, resulting in increased ridge width. This was confirmed on dentascan and 3D reconstruction images. Implants were placed and restored with satisfactory aesthetic and functional outcome.
