Osteonecrosis of the jaw in a patient with rheumatoid artritis treated with an oral aminobisphosphonate: a clinical case report.

Osteonecrosis of the jaw (ONJ) has been recently described after intravenous administration of amino-bisphosphonates and - less frequently - in association with the use of oral bisphosphonates. Bisphosphonate-Related Osteonecrosis of the Jaw (BRONJ) may affect mandible bone (65%), maxilla bone (26%) and rarely (9%) both sites simultaneously. Although causality may never be proven, emerging experimental data have established a strong association between monthly intravenous bisphosphonate administration and ONJ.
