Bisphosphonates: osteonecrosis of the jaw. obvious cause. Research suggests a link between ONJ and the following osteoporosis medications: alendronate. Although the pathogenesis of MRONJ is not entirely clear, multiple factors may be involved in specific microenvironments. The unique environment of the jaw can lead to cavities forming through prolonged bisphosphonate use. The complication with bisphosphonates, often prescribed to treat osteoporosis, is a risk for jaw osteonecrosis. You may be prescribed these medications if you have: Multiple myeloma or other cancers. Medication-related ONJ Osteonecrosis of the jaw may develop during or a#er treatment with bone strengthening medications including bisphosphonates and denosumab.

The study suggested that those with the gene variation and on long-term or higher dosage bisphosphonates have a 5.8 times higher risk of developing osteonecrosis of the jaw with time.
