There are two forms of sinus lift procedures and the form you receive depends on your individual needs and the amount of bone you still have. Your doctor will discuss your options prior to the procedure.
Before the procedure begins, a local anesthetic is applied to the site. The doctor will then create a small opening in the bone to access the sinus cavity. Using a small instrument, the doctor will then gently lift the sinus back to its original position. A grafting material is then placed beneath the newly raised sinus cavity along the existing bone. This grafting material will then mesh with your bone, thus creating more bone.
