title: [Osteonecrosis of the jaws as a possible adverse effect of the use of bisphosphonates].
abstract: BACKGROUND
  Bisphosphonates are widely used in the treatment of cancer patients with hypercalcemia and bone metastases or in osteoporosis therapy. Current reports have focused on therapy-resistant osteonecrosis of the jaws as a possible side effect of bisphosphonates. Official German drug committees have recently warned about the possibility of these side effects in the publication organs Deutsches Arzteblatt and Deutsche Apotheker Zeitung.
  
  
  METHODS
  So far we have had experience with seven patients showing therapy-resistant osteonecrosis of the mandible under bisphosphonate medication. The presentation of these cases is intended to call attention to this clinically important side effect of bisphosphonate medication.
