ABSTRACT Objective Medication‐related osteonecrosis of the jaw (MRONJ) is a rare but debilitating disease characterized by a progressive necrosis of jaw bones in patients who have received anti‐resorptive or anti‐angiogenic therapies. Unfortunately, we still have no validated preventive or pharmaceutical interventions to help these patients, primarily due to our limited understanding of MRONJ pathogenesis. Here, we offer an extensive review of recent studies relevant to MRONJ pathogenesis. We present a hypothesis regarding the coupling of bone resorption and angiogenesis that relies on osteoblast‐derived, matrix‐bound vascular endothelial growth factors to explain why ONJ is associated with both anti‐resorptive and anti‐angiogenic agents. Methods A narrative review was conducted by searching databases, including PubMed, Scopus, Google Scholar, and Web of Science, to retrieve relevant reports. Results Reduced bone resorption leads to reduced angiogenesis, and vice versa, creating a vicious cycle that ultimately results in ischemic necrosis of the jaw. Additionally, we suggest that reduced angiogenesis, induced by anti‐resorptive or anti‐angiogenic agents, aggravates bacterial infection‐induced bone necrosis, explaining why the jaw bone is particularly susceptible to necrosis. Conclusion Our novel hypothesis will facilitate the advancement of future research and the development of more targeted approaches to managing MRONJ.
