What are sinus lifts?
Sinus lifts- The maxillary sinuses are behind your cheeks and on top of the upper teeth. Sinuses are like empty rooms that have nothing in them. Some of the roots of the natural teeth extend up into the maxillary sinuses. When these upper teeth are removes, there is often just a thin wall of bone separating the maxillary sinus and the mouth. Dental implants need bone to hold them in place. When the sinus wall is very thin it is impossible to place dental implants in this bone. The only solution is a sinus lift. The periodontist enters the sinus from where the upper teeth used to be. The sinus membrane is then lifted upward and bone graft is inserted into the floor of the sinus. The bone then becomes part of the patients jaw and dental implants can be inserted and stabilized in the new sinus bone.
