Though surgeons have the experience and expertise to do bone graft surgery, proper aftercare is essential to the procedure’s success. One reason for bone transplant failure is your general health. To keep the bone in place, the gums, teeth, and tissues must be strong. The implant will only be placed after the bone has absorbed the material and become a fully integrated region. Bone graft infection: A bone graft’s failure is most likely caused by infection. It is not often seen, but various circumstances cause it. Contaminated and non-sterilised bone grafts Unqualified surgeons or dentists use incorrect surgical techniques. The instruments and field of surgery were contaminated. Unsatisfactory postoperative care Infection symptoms can appear shortly after a dental bone or other bone graft is placed. Individuals may experience swelling, redness, malaise, dysgeusia, halitosis, fever, pain, or bleeding.  Exposed bone graft: Due to gingival recession, the bone graft might protrude from the gums and be exposed. When the blood supply to the grafted tissue is interrupted, it gets damaged. It can be managed by taking antibiotics if it’s caught early. If the situation is severe, additional surgery will be done to remove the bone graft. Smoking or use of tobacco: Cigarettes contain nicotine, carbon monoxide, and hydrogen cyanide, which can negatively impact bone vascular reconstruction and can jeopardise the healing of the wound.  Medical condition: Patients with uncontrolled diabetes may suffer from systemic conditions. Diabetes can cause complications such as osteopenia and delayed bone healing, which can ultimately cause bone graft failure. The following factors can also cause bone graft failures: Mistakes made during surgery Immunodeficiency disorders Periodontal disease (gum disease) Osteoporosis
