What is the success rate of dental bone grafts?
Composite bone grafts have 99.6% survival rate and 66.06% success rate. Allografts have 90.9% survival rate and 82.8% success rate.
Can dental bone grafts be rejected?
The success rate for bone grafts in the jaws for the purpose of placing dental implants is very high. However, there is always a chance that the bone graft will fail, even if your own bone was used. Bone grafts are not rejected like organ transplants.
Is dental allograft safe?
In particular, allografts, being a natural, human biological matrix and readily available have proven clinically reliable. However, not all allografts are equal in terms of processing, sterility, and proven clinical performance for dental applications.
What happens if your body rejects a bone graft?

What is allograft rejection and how does it work?
Allograft rejection is the consequence of the recipient’s immune response to nonself antigen released by the donor tissues. Allograft tissues work on the principle of osteoconduction. Let’s imagine, a vine growing through a trellis. The allograft tissue also works in the same pattern.

What are the risks of freeze-dried bone allografts?
When using freeze-dried bone allograft and demineralized freeze-dried allograft, the delay in processing ensures that there is time to test them for any pathogens. The usual risks seen in other surgical procedures also hold true for grafts. These include pain, infection, or swelling.
