In many situations, the successful placement of dental implants requires hard and soft tissue regeneration techniques. The decision to utilize a block allograft, an autogenous block, or particulate bone must be evaluated for each alveolar ridge defect the clinician encounters. When a block graft is indicated, the surgeon must choose between an allograft block or autogenous block. With the advent of recombinant human bone morphogenetic protein 2 and platelet-derived growth factors to enhance the success rates, the indications for autogenous grafts are diminishing. This presentation will discuss the principles, indications, and limitations of block allografts and the surgical sequence designed to ensure predictable placement of block allografts. The defects and locations most likely to be successfully treated, as well as hard and soft tissue limitations and their required corrections, will be identified. In addition, the presentation will discuss which growth factors will most significantly enhance the success of allograft block grafts.
