AI Article Synopsis
- Elevating the sinus floor is important for properly placing oral implants, but the anatomy of the maxillary sinus can complicate the procedure.
- A study involving 150 sinuses from cadavers and 35 patients revealed that 61% had no significant bony septa, while 39% had varying degrees of bony septa, which can affect the implantation process.
- The findings highlight the challenges posed by intramaxillary sinus septa during sinus floor elevation and underscore the need for careful anatomical consideration in dental procedures.
Article Abstract
Elevation of the sinus floor allows the correct number and length of oral implants to be placed. The sinus membrane is dissected blindly, usually by a crestal approach, but several internal configurations of the maxillary sinus or intrasinus septa can cause problems. We studied 150 sinuses from 40 male cadavers, and 35 randomised male patients by anatomical dissection and computed tomography. Forty-six subjects (61%) had no bony septa or had septa less than 4mm. Twenty-nine (39%) had bony septa of which seven were incomplete, one had a complete bony septum in each maxillary sinus, and 20 had symmetrical bony septa. We present the results of a study of bony intramaxillary sinus septa and the potential problems they can cause during elevation of the sinus floor.
