When you are missing back teeth (molars) in the upper jaw, the combination of bone reabsorption and low sinus cavities can affect your opportunity for dental implants. The back areas of the upper jaw contain a smaller amount of bone compared to the lower jaw. This bone loss can be reversed with proper treatment, often paired with a sinus lift.
Scans are used to identify the width and height of your existing bone to determine the extent of treatment that is required. During the procedure, the surgeon opens the affected area and packs the lower area of the sinus with bone graft material. Over time, the grafted material will fuse with your bone, creating a stronger foundation that can support a dental implant four to nine months later.
