Often patients who have lost teeth in the upper jaw require a sinus bone graft in order to have dental implants placed. This is because the bone in the area where teeth are missing naturally begins to shrink, or reabsorbs, over time, with insufficient bone to securely place the dental implant, a sinus bone graft is necessary to place additional bone in the area.
There are two types of sinus lift procedures, and the one you receive depends on your individual needs and the amount of bone you still have. The 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.
Usually, patients require 4-9 months to heal completely from the sinus lift procedure before dental implants can be placed. This increase in bone will compensate for bone loss and will allow for multiple implants to be placed. Without this procedure, many patients will not qualify for dental implants.
