Sinus lift: making room for upper-jaw implants
In the upper back jaw, the maxillary sinus sits just above where implants go. When there is not enough bone height beneath it, a sinus lift creates the room an implant needs.
The anatomy
What a sinus lift actually is
The maxillary sinuses are air spaces behind your cheekbones, above the upper back teeth. After teeth in that area are lost, the bone between the mouth and the sinus often thins — partly from natural bone change, partly because the sinus can expand into the space over time.
A sinus lift (sinus augmentation) addresses this directly: your surgeon gently raises the sinus membrane and places grafting material beneath it. As the graft integrates, it becomes bone with enough height to hold an implant securely.
When it comes up
When a sinus lift is considered
- You want an implant for an upper back tooth, and imaging shows limited bone height below the sinus
- Teeth in the area have been missing for a while, and the site has changed
- A full-arch upper restoration is planned and the back of the arch needs support
Whether you need one is a measurement question, not a guess. 3D imaging shows your surgeon the exact bone height and sinus position before anything is recommended.

Sequencing
How it coordinates with implant planning
Depending on how much bone you start with, the sinus lift may be done as a separate procedure with implants placed after the graft matures, or — when enough native bone exists to stabilize an implant — at the same visit as placement. Your surgeon explains which sequence your anatomy supports and why.
Healing time varies by patient and by the size of the graft; your surgeon confirms the site is ready with imaging before the implant carries any load. Aftercare has a few sinus-specific rules — such as avoiding forceful nose-blowing for a period — which your written instructions spell out.

Imaging at your consultation will show whether a sinus lift is part of your path — and what the sequence would look like.
