Medical surgery needed. Allowed?

Shalom. I have a medical question. A year ago, I got a tooth infection. We thought it was gone, but have now found that it is in my jaw and has eaten some of my jaw bone over the past year. My hyper immune system kept it from spreading further. Unfortunately, I've been told the antibiotic cannot kill the infection due to its severity. The doctors have to remove it surgically, but removing a part of my jaw bone and doing two bones grafts, one on each of my lowers sides. I've let him know I'm Jewish, and he said the cadaver donor bone will be human. Without the graft, my immune system will stop protecting me eventually and it could spread to become life threatening. Does the law allow me to have this bone graft? Also, I don't know if it matters by law, but I've already been dead three times. Twice for over an hour. Drowning and allergic reaction to medication. Does my own previous death disallow me from using another dead body in my body?

Shalom!

Thank you for your question.

You are permitted to receive the bone graft no matter who or what is the donor.

Wishing you health and long life!
