If you've lost bone density Bone grafts are an operation that assists in create new bone. It is used to repair bone damaged by gum disease or to strengthen jawbones that are thin before dental implants are put in.
Bone grafts are autologous (from your body) or allograft (cadaveric bone that is usually sourced from bone banks) as well as synthesized bone (man-made). They are utilized to fill in areas that have lost bone through injury or by periodontitis.
