The “Phoenix Jaw” Phenomenon Revisited: Two Cases of Bisphosphonate-Related Mandible Osteonecrosis Surgically Treated with Complete Bone Regeneration

Abstract

Bisphosphonate-related osteonecrosis of the jaws represents a well-recognized complication occur-ring in patients being administered drugs for the treatment of osteoporosis and/or malignant disease. Treatment of this condition, aiming to alleviate the symptoms and restore functional status, represents a challenge for the maxil-lofacial surgeon. Conservative management has been proposed for early stages of this condition, while surgical intervention is mandatory for advanced disease. Two cases of severe bisphosphonate-related osteonecrosis of the jaw that achieved complete osseous recontouring after partial mandibulectomy, are presented.
