Study Notes
Anatomical Structure of Maxillary Sinus
- The Schneiderian membrane separates the maxillary sinus from the molar dentition.
Proximity of Teeth to Maxillary Sinus
- Molars are closer to the maxillary sinus than premolars.
Distance between Maxillary Posterior Teeth and Sinus Floor
- The mean distance between the maxillary posterior teeth and the floor of the sinus is approximately 1.5-2.5 mm.
Thickness of Sinus Membrane
- The membrane lining the maxillary sinus in a healthy state is approximately 0.5-1 mm thick.
Risk of Perforation during Sinus Lift Procedures
- The chances of perforation during sinus lift procedures increase when the residual bone height is ≤ 4 mm.
