Denture-related osteonecrosis of the maxilla associated with oral bisphosphonate treatment.
BACKGROUND
Bisphosphonates are a class of agents used to treat various systemic conditions. Despite the benefits of bisphosphonates, osteonecrosis of the jaws is an important complication in a subset of patients who receive this drug treatment.


METHODS
A 66-year-old woman was referred to an oral surgeon at a private surgical center because of a pressure wound in the margins of a removable maxillary denture. The patient reported that she had received oral alendronate sodium treatment for eight years. A clinical examination revealed a palatal ulcer with exposed necrotic gray bone at its center. The clinician performed an excisional biopsy and separated two palatal rotational flaps to enable an adequate blood supply to reach the operated-on area.


CONCLUSIONS
This report, together with growing evidence in the literature, serves to alert treating physicians and dental practitioners about the potential complication of maxillary and mandibular bone necrosis in patients receiving bisphosphonate therapy.
