[Sunitinib and zoledronic acid induced osteonecrosis of the jaw].

The tendency for bisphosphonate and non-bisphosphonate (eg.: antiresorptive or anti-angiogenesis drugs) induced osteonecrosis is increasing. Treatment of these patients is a challenge both for dentists and for oral and maxillofacial surgeons. Cooperation with the drug prescribing general medicine colleagues to prevent osteonecrosis is extremely important. Furthermore, prevention should include dental focus elimination, oral hygienic instructions and education, dental follow-up and, in case of manifest necrosis, referral to maxillofacial departments. Authors outline the difficulties of conservative and surgical treatment of a patient with sunitinib and zoledronic acid induced osteonecrosis. The patient became symptomless and the operated area healed entirely six and twelve months postoperatively. A long term success further follow-up is necessary to verify long-term success.
