Demand for banked bone allografts is increasing in Japan; however, there are too few bone banks and the bone bank network is not wellestablished. One reason for this was lack of funding for banks. Bone banks had to bear all material expenses of banked bone allografts themselves because this was not designated a covered expense. In December 2004, the Japanese government started a new ...

The main concerns of allograft use are the risk of disease transmission and the limited availability. A report showed that in the UK, the availability of bone allografts greatly exceeded the demand. 8 This may be the case in the UK where tissue banks are well developed, but worldwide there are still shortages of bone allografts. Nonetheless, the availability of human bone allografts is not the ...

Demineralized Bone Matrix (DBM) DBM is bone processed in such a way that the calcium in the bone is removed. The benefit of this process is that it makes important proteins available to stimulate bone healing. The disadvantage of this graft is that there are no cells that can form bone. Like allografts, DBM serves as a scaffold for bone to grow.

Allografts Allografts are transplanted organs or tissue from one individual to another of the same species with a different genotype. For example, a transplant from one person to another, but not an identical twin, is an allograft. Allografts account for many human transplants, including those from cadaveric and living donors. Also known as an allogeneic [.]
