Compact bone
Compact bone
A layer of dense, hard bone that separates the maxillary sinus from the molar teeth.
Which teeth are closer to the maxillary sinus: molars or premolars?
Which teeth are closer to the maxillary sinus: molars or premolars?
Molars are situated closer to the maxillary sinus because they are positioned towards the back of the mouth.
What is the average distance between the maxillary posterior teeth and the sinus floor?
What is the average distance between the maxillary posterior teeth and the sinus floor?
The average distance between the maxillary posterior teeth and the sinus floor is approximately 2 millimeters.

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.
