[Osteochemonecrosis of the jaws and bisphosphonates: a case report and literature review].

[Bisphosphonates and maxillo-mandibular osteo(chemo)necrosis].

Introduction: Maxillo-mandibular osteonecrosis is exceptional outside a context of cervico-facial radiotherapy. Bisphosphonates are non-metabolized pyrophosphate analogues which inhibit osteoclastic activity. Bisphosphonates are prescribed for the treatment of malignant hypercalcemia, osteolysis associated with metastatic bone disease, Paget's disease and osteoporosis.
