Osteonecrose mandibular associada ao uso de bisfosfonatos tratada com plasma rico em fibrina leucocitária: relato de caso

A serious complication of their use is osteonecrosis of the jaw, defined as an area of exposed bone in the maxillofacial area without resolve spontaneously over a period of at least 8 weeks in patients with history of use of bisphosphonate compounds, but which have not been subjected to radiotherapy in the head and neck.
