Aspergillosis is a fungal disease caused by the fungus Aspergillus; this disease frequently involves the lungs and occasionally the maxillary sinus. Aspergillosis in the maxillary sinus usually has the characteristics of a noninvasive form. It has been suggested that spores of aspergillus can be inhaled into the maxillary sinus via the osteomeatal complex or via an oroantral fistula after dental procedures, such as an extraction. However, maxillary aspergillosis related to implant installation has rarely been reported. This report regards unusual cases of maxillary aspergillosis associated with dental implant therapies in healthy patients. The cases were successfully treated with the surgical removal of the infected or necrotic tissues.
