Medication-related osteonecrosis of the jaw (MRONJ) is a rare but serious side-effect of antiresorptive therapies used in the management of bone diseases, such as osteoporosis or bone metastases. A surgical management can lead to a resolution of the disease, but with perfectible results. For this purpose, the use of autologous platelet concentrates (APC) can be useful. With this study, researchers aim to demonstrate the efficacy of L-PRF (Leukocyte- and Platelet-Rich Fibrin) as an adjunct to the surgical treatment of MRONJ in terms of wound healing.
