ABSTRACT: Subperiosteal implants are generally used in the severely
resorbed areas, and although dwindling in use, they have shown to be successful
treatment options for the edentulous dental patients. We report a case of
maxillary subperiosteal implantitis that caused sinusitis. A 59-year-old man
was referred to our clinic in March 2003 with a chief complaint of pain and
swelling in the bilateral upper molar region. He received a surgical
operation for maxillary subperiosteal implant at another dental clinic in April
2001. CT scans demonstrated that the radiopacity of the right maxillary sinus
extended to the ethmoid and frontal sinuses. Extensive surgical debridement was
performed. The radiopacity of the right maxillary sinus in CT almost
disappeared in a month. Two months later, the occlusal function was recovered
using a new maxillary complete denture. The patient has had no symptoms and no
occlusal disturbance by the denture for more than nine years.
