Detailed explanation-1: -What causes osteonecrosis of the jaw? ONJ tends to occur after oral surgery like a tooth removal (extraction), dental implant or dental bone graft that may leave some of your jawbone exposed. In osteonecrosis of the jaw, your gum tissue doesn’t heal after your dental procedure and your jawbone is left exposed.
Detailed explanation-2: -Can you prevent osteonecrosis of the jaw? There is no known prevention of ONJ. However, to reduce the risk, all patients taking bisphosphonates should get regular dental checkups.
Detailed explanation-3: -It can be caused by radiation, high-dose steroid therapy, and medications that disrupt vascular supply or bone turnover in the jaws. Malignancies of, or metastatic disease to, the jaw can also result in osteonecrosis and subsequent exposure of the jaw bones.
Detailed explanation-4: -[6] Due to altered wound healing, delayed epithelial closure of a mucosal opening in the mouth leads to chronic infection and the necrosis of bone. [7] Osteonecrosis develops in the jaw because this bone has a higher remodeling rate than other bones, making it more prone to the effect of bisphosphonates.
