A protocol for the treatment of complications involving the maxillary sinus after dental implant placement has not yet been established. Six patients (2 males, 4 females ; mean age 60.8 years) treated for maxillary sinus complications after dental implant placement in our department over the past 10 years were analyzed statistically, and methods of preventing and treating maxillary sinus complications were considered.<br/>Two of the six patients experienced displacement of the dental implant body into the maxillary sinus, and five patients developed maxillary sinusitis because of extrusion and displacement of the dental implant and leakage of bone substitute into the maxillary sinus noted upon initial examination. Four patients complained of swelling and pain at the buccal region. The two patients with dental implant displacement had few subjective symptoms. Retrieval of dental implants displaced into the maxillary sinus was planned for two patients, but the dental implant of one patient was accidentally swallowed before the operation.<br/>Treatment of the maxillary sinusitis with irrigation of the maxillary sinus and administration of antibiotic medication were effective, and no signs of residual sinus infection were observed in any of the patients after treatment. Our treatment procedures may prevent the need for removal of dental implants and bone substitute.
