Effectiveness of Platelet-Rich Fibrin in the Surgical Management of Medication-Related Osteonecrosis of the Jaw: A Randomized Prospective Study

Detailed Summary

Medication-Related Osteonecrosis of the Jaw (MRONJ) is a severe and increasingly prevalent clinical condition, defined as the presence of exposed mandibular or maxillary bone in the oral cavity persisting for at least eight weeks. The rising incidence of osteonecrosis of the jaw is closely associated with the widespread use of antiresorptive agents, such as bisphosphonates and denosumab, particularly in patients treated for malignant diseases and metabolic bone disorders. The condition is frequently accompanied by pain, inflammation, infection, and functional impairment, all of which significantly reduce patients' quality of life. Despite advances in medical management, conservative treatment strategies have demonstrated limited effectiveness, especially in advanced stages of the disease. Surgical intervention, including resection of necrotic bone or segmental bone resection with removal of necrotic tissue, has been shown to provide more favorable outcomes. However, surgical treatment remains associated with a considerable risk of postoperative complications, delayed or impaired wound healing, and recurrence of symptoms. One promising adjunctive approach is the use of platelet-rich fibrin (PRF), an autologous biomaterial with documented regenerative and anti-inflammatory properties. PRF has been used in oral and maxillofacial surgery for over a decade and may enhance both soft tissue and bone healing. The application of PRF to fill the post-resection defect and, when necessary, to cover the surgical site in cases of insufficient mucosal tissue has shown encouraging results. Evidence from individual case reports, animal studies, and preliminary clinical trials suggests that PRF may improve wound healing, reduce postoperative complications, and decrease the risk of disease recurrence. The aim of the present study is to evaluate the effectiveness of PRF as an adjunctive treatment in the surgical management of osteonecrosis of the jaw. Patients will be assessed at predefined follow-up intervals of 14 days, 6 weeks, and 6 months postoperatively. Study participants will be allocated to a control group receiving standard surgical treatment and a study group undergoing surgical treatment supplemented with PRF application. Comparative analysis between the groups will be performed to assess treatment outcomes.
