There are two types of bone powder used for dental implants: the first is autologous bone, which means that during the implantation process, we use a drill that can carry bone to prepare our implant socket, and during the preparation of the implant socket, the amount of bone is completely preserved and used for bone grafting in other parts of the body later on. The effect of autologous bone grafting is very good, but its disadvantage is that the amount is small and it is only suitable for bone grafts with small defects. The second type of bone powder is the kind of bone powder we sell in the market, which is bovine bone. The domestic bone powder is not very effective at the moment, but mainly the imported Bioss bone powder, which is usually combined with our bone, but eventually cannot be completely transformed into autologous bone.
