Rebuilding the Ridge: The Role of Block Bone Grafts in Implant Site Development
Abstract: Adequate alveolar bone volume is essential for successful implant therapy, ensuring optimal implant placement, primary stability, and long-term functional and esthetic outcomes. However, significant horizontal and vertical ridge resorption commonly occurs following tooth extraction, often compromising implant placement. In cases of severe ridge deficiencies, block bone grafting has emerged as a predictable technique for three-dimensional alveolar ridge reconstruction. This review summarizes the biological principles, surgical protocols, graft materials, and clinical outcomes associated with block bone grafting. Autogenous block grafts remain the gold standard due to their osteogenic, osteoinductive, and osteoconductive properties, although donor-site morbidity has led to the development of alternatives such as allogenic, xenogenic, and synthetic grafts. Recent advancements including CAD/CAM-customized grafts, biologic adjuncts such as platelet-rich fibrin and bone morphogenetic proteins, and minimally invasive surgical techniques have further improved treatment outcomes. These developments highlight the evolving role of block bone grafting as a reliable approach for managing complex alveolar ridge defects and facilitating predictable implant rehabilitation.
