Abstract: Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a serious adverse reaction caused by long-term use of bisphosphonate in patients. Its main symptoms include soft tissue rupture, bone surface exposure, necrotic area flow pus, focal tooth loosening and so on. Because of the unclear etiological mechanism and lack of corresponding etiological treatment, the current clinical treatment is mainly local dead bone removal and other symptomatic treatment. Scholars have proposed different etiological mechanisms, including imbalance of the bone turnover of the jaw, inhibition of angiogenesis, microbial infection, immune dysfunction, soft tissue toxicity and so on. The recent research progress in the pathogenesis of the disease is reviewed in this paper.

Key words: BRONJ, osteoclast, bone metabolism
