Abstract

Minimal bone height for sinus crestal approach at upper molar site for implant placement was more than 5 mm. When the septum was located at implant installation site, it had a risk of membrane perforation. However, it was useful for initial fixation due to its high bone density. A 54-year-old patient had a septum at left upper 1st molar site. Implant installation was performed using sinus crestal approach using the fixing force of the septum. The 7-year follow-up revealed that the bone and implant conditions were maintained without any complications.
