Dental implants are widely used for partially or fully edentulous patients, however, cases of maxillary sinusitis caused by dental implants have been reported.
We treated 26 such patients in Osaka Dental University hospital from 1973 to 2001. A clinical analysis was performed in 27 cases, and the results were as follows:
1. Of the 26 cases, 10 patients were males and 16 patients were females; the mean age was 54.5 years old.
2. Type of implants: 19 patients received endosteal implants, 7 were fitted with subperiosteal implants and 1 got endodontic and endosteal implants.
3. The period from implant insertion to symptoms of maxillary sinusitis: 7 patients (25.9％) had onset within a month and 9 patients had onset within a year (33.3％).
4. Period from symptoms to diagnosis: 12 cases (44.4％) were diagnosed within a month and 20 cases (74.1％) were diagnosed within 6 months.
5. To prevent maxillary sinusitis, investigation of the volume of maxillary bone is required, followed by choosing the proper surgery method and type of implants.
6. It is important to quickly decide whether sinus surgery is necessary or not and to remove implants causing maxillary sinusitis if they perforate the maxillary sinuses.
