Sumario:INTRODUCTION: Medication Related Osteonecrosis of the Jaw (MRONJ) is an adverse effect of antiresorptive and antiangiogenic agents that consists of progressive bone destruction in the maxillofacial area. The purpose of this study is to analyze the effect on bone volume of a surgical protocol using plasma rich in growth factors (PRGF) for successfully treating MRONJ. METHODS: Three patients were treated combining surgical debridement with PRGF. Cone bean computed tomography scans were taken prior to surgery and 12 months after to measure bone volume changes. Biopsies were taken for histology analysis during surgery. RESULTS: All patients showed a complete soft tissue and bone healing with pain, discomfort, and neural symptoms resolution for a follow up period of 30 months. A total of 12 to 30% of bone volume gain was found at 12 months after surgery. CONCLUSIONS: PRGF in combination with surgery may be effective in treating MRONJ. Future trials must be performed to confirm these results, including bone volume analysis.
