Plain X-rays may be normal in the early stages, but later show poorly defined osteolysis with or without sequestrum formation.
Association of Oral and Maxillofacial Surgeons position paper: No adjustment or interruption in the premeditated oral surgery is necessary for patients who have been on oral bisphosphonates for less than 3 years and have no clinical risk factors. The incidence of ONJ in patients receiving high-dose bisphosphonate treatment for metastatic malignancy is much higher.
