If you lose posterior teeth, it causes an increase in force to be placed on your remaining teeth, which can affect both your bite and oral health. This is why replacing extracted teeth is so important. Dental implants provide a long-lasting solution to filling gaps in patients’ smiles, but sometimes there is not enough room in the upper jaw for dental implants to be placed. This can be because of the position of the sinus or because of bone loss.
A sinus lift or augmentation, allows the sinus floor to be repositioned and bone added so that there is enough space for the implant to be inserted. For this procedure, Dr. Michael Corsello uses a variety of grafting materials to encourage bone to grow more quickly into the area and help stabilize the dental implant.
The bone used in a sinus lift may come from your own body (autogenous bone), a donor (allogeneic bone) or from cow bone (xenograft). During the procedure, the doctor will cut the gum tissue where the missing back teeth used to be in order to expose the bone. Then he will open a small oval window to the bone to gain access to where the sinus meets the jaw. The sinus is pushed up and away from the jaw, and granules of bone-graft material are then packed into the space where the sinus was, adding several millimeters of bone to the jaw.
Once the bone is in place, the tissue is closed with stitches and left to heal. Implants are usually installed four to nine months later while the grafted material meshes with your bone.
