[Osteonecrosis of the jaws by using bisphosphonates].

The new generation of bisphosphonates are often used in the treatment of osteoporosis or for certain tumors with bone defects. Between the period of September 2005 and May 2006 we have treated 8 patients at our clinic with a bisphosphonate-induced osteonecrosis in the maxillofacial region. All of these patients went through intravenous bisphosphonate treatment earlier.
