maxillary sinus


Methods: The maxillary sinus was intentionally perforated for dental implant placement in 35 patients with reduced posterior maxillary bone height (4 mm or more). A total of 70 implants engaged bicortically and emerged into the sinus. Nineteen female and 16 male patients were involved in the study. The patients were followed up for sinus complications and dental implant success.

Results: From the total, only two implants were failed; one during gingival former placement and the other after loading by one year. No patient presented with sinusitis clinically and radiographically. Three patients developed epistaxis just on the day of surgery and became well after on.
