Sinus Grafting (Sinus Lift)

A sinus lift, or sinus graft, adds bone beneath the maxillary sinus in the upper jaw. It creates enough bone height to support dental implants in the back of the mouth.

After upper back teeth are lost, the bone often thins and the sinus can expand downward. A sinus graft restores the bone needed for secure implant placement.

A crestal approach raises the sinus floor through the implant site and is used for moderate bone loss. A lateral-window approach accesses the sinus from the side of the jaw for larger grafts.

When enough bone remains to stabilize the implant, it can often be placed at the same visit. If bone is very limited, the graft heals first and the implant follows later.

The procedure is performed under local anaesthesia, so patients remain comfortable. Most describe recovery as similar to having a tooth removed, with mild swelling for a few days.

Healing typically takes four to nine months, depending on the size of the graft. During this time, the graft matures into bone capable of supporting an implant.

The procedure works beneath the sinus membrane, so breathing is not affected. Mild congestion may occur during the first few days and usually resolves on its own.

Avoid blowing your nose forcefully, sneeze with your mouth open, and avoid using straws during early healing. These precautions protect the graft and the sinus membrane.

A 3D CBCT scan measures the bone beneath the sinus and maps surrounding anatomy. This imaging guides the choice of technique and the timing of implant placement.

Costs depend on the technique used, the amount of graft required, and whether the implant is placed at the same time. A consultation with CBCT imaging provides a detailed cost estimate.
