This paper aimed to summarize and revisit the three most recognized practice guidelines for the management and prevention of MRONJ, which were proposed by the American Association of Oral and Maxillofacial Surgeons (AAOMS), and presented by the Journal of Bone and Mineral Research (JBMR) and the Journal of Clinical Oncology (JCO). Results and case studies: The AAOMS position paper focused on risk stratification by different medications, management decision trees, risk factors, pathophysiology, and disease staging. The JBMR international consensus presented eight focused questions, which were addressed by systematic reviews. The JCO clinical practice guideline presented six clinical questions, and each concluded with practical recommendations. Practical information was summarized and converted into an adoptable patient care workflow for clinicians to follow and apply in daily practice. Three case studies presented were treated following these guidelines. Each patient underwent advanced surgeries including alveoloplasty, tooth extraction, implant placement, and particulate bone grafting. Some of the considerations not fully informed were discussed and illustrated in each step of the patient care workflow, which included specifics for risk communication, updates on the use of antibiotics, biomarkers, and drug holidays.</p><p><strong>Conclusion and practical implications: </strong>Structured risk communication with official informed consent documentation should be considered before initiating invasive treatments.
