How to Prepare Patients Receiving Antiresorptive Therapy for Tooth Extraction: A Narrative Review

Bisphosphonates (BPs) and Denosumab (DMB) are antiresorptive agents (AA) commonly used in treatment of osteoporosis, multiple myeloma (8.0%), breast cancer (3.3%), prostate cancer (2.9%) and other malignancies (0.7%), bone metastases, and cancer-induced hypercalcemia. However, this therapy is associated with a significant risk of medication-related osteonecrosis of the jaw (MRONJ), particularly after tooth extraction. The aim of this narrative review was to summarize current evidence on measures aimed to reduce the risk of MRONJ after tooth extraction, and to critically discuss the strength of evidence supporting each of these measures. Articles published in the years 2013-2025 were reviewed using PubMed, Scopus, Web of Science databases. Available studies were categorized and compared with the use of selected prevention methods. The duration of the treatment, route of administration, dosage and type of AA have a significant impact on the risk of developing MRONJ. Antibiotic prophylaxis is considered in most published preventive protocols. However, the evidence supporting a single optimal regimen is limited. Patients from a high-risk group of MRONJ, demonstrating cancer, who were administered intravenous antiresorptive agents for longer than three years or zoledronic acid, or those with a history of jawbone necrosis or inflammation require prolonged antibiotic therapy (started before the procedure and continued up to 14 days after the procedure). Moreover, studies on the use of platelet-rich fibrin (PRF) and Concentrated Growth Factors (CGF) as a preventive measure have shown promising results in observational studies, along with antibiotic prophylaxis and optimal oral hygiene. Pentoxifylline with tocopherol and low-level laser therapy (LLLT) are recognized as potentially useful non-invasive preventions. However, evidence is limited due to the small sample sizes and heterogenous protocols. Vitamin D levels should be monitored, and oral supplementation should be considered if needed. AA therapy suspension prior to the surgical procedure must always be consulted with the attending physician. A multidisciplinary approach along with well-planned pre- and postoperative care is essential for safe tooth extraction in patients receiving AA therapy.
