A dental bone graft is a procedure that grafts a section of bone from another area of the body onto the jaw bone. A successful bone graft creates a jawbone strong enough to support a dental implant. A small incision is made in the gum to gain access to the bone that will be grafted. Next, the grafting material is added by transplanting a piece of bone from a part of the body into the jawbone or by using bone taken from a cadaver or an animal source. Over the next couple of months, the body will replace the graft with its own bone and reverse the decline in bone quantity.
