Abstract
Short implant procedures may suffer from fixture instability, if incorrectly planned and performed, and from an esthetically compromised rehabilitation, due to increased interarch distance and increased crown-implant ratio. Several procedures have been proposed to achieve alveolar ridge augmentation with different success and complication rates: onlay grafts, alveolar sandwich osteotomies, titanium micromesh, alveolar distraction, and alveolar nerve transposition. The edentulous posterior mandible suffers from the presence of a compact cortical layer, which tends to limit graft osteogenesis, because of a low permeability to the osteogenic elements (microvessels and cells). This report introduces a variant to the endochondral onlay bone graft, in which an external cortical layer is placed above a biologically active core of cancellous bone and platelet-rich plasma. This solution provides easy 3-dimensional conformation of the graft, enhancing its mechanical stability. The presence of the biologically active core provides better vascular support and a valid interface between graft and the osteogenetic cell lines.
