Bone cows, specially bred in Australia where mad cow disease is free, can be used instead of human donors for tooth and bone grafting. reports news portal The Guardian.
In the past, dental bone grafts were made using the bones of people who consented while they were alive. Now, synthetic materials as well as xenografts – animal bones can often be used instead.
Xenotransplantation is a type of transplantation that involves using animal parts to transplant into humans amid an implant shortage made worse by the pandemic. Australian cattle are best suited for this purpose because there is no history of bovine spongiform encephalopathy (mad cow disease).
They undergo regular medical check-ups and are then sent to slaughter. The resulting material is sent abroad for high-temperature processing, cleaning and sterilization. It is then returned to Australia where it is used to create a biocompatible implant.
