-Corticocancellous Mineralized/Demineralized, It is a premium graft offering which combines approximately 70% mineralized cortical bone with 30% demineralized cancellous bone plus bmp-2 in an optimal mixture for rapid bone regeneration. Corticocancellous is a compinition of" cortical & spongy, it comes from sections of the illium which are ground into several particulate sizes. The blend of cortical and cancellous that results from this process gives this product the structure of cortical, with the open scaffolding for bone to grow into offered by cancellous, Cancellous bone, also known as spongy or trabecular bone, is porous bone that allows for increased blood flow around a graft site, Cortical bone is manufactured from long bones such as the femur, tibia, fibula, and humerus. Cortical bone is dense compact bone that will maintain space in a graft site. Slower resorption time than cancellous bone means this graft is good for maintaining space. So in Garantie Regain -Oss a natural mix of cortical and cancellous bone particles offering the dual advantage of slow resorbing, space maintaining cortical bone and relatively faster remodeling, optimally osteoconductive cancellous bone in one single allograft product.
