What is a sinus lift procedure and why do I need one before my dental implants?

The upper jaw or maxilla is a complex bone in the mid face that houses the upper teeth and comprises of the roof of the mouth, the floor of the nasal cavity, the floors of the eye sockets and the sinuses. The maxilla has one pair of sinuses, either side of the nose. These cavities are empty spaces that make the bones lighter. They are lined with a membrane and can get filled with mucus when the patient has a head cold and occasionally other pathology.
