Sinus Lift: What It Is, Recovery, and Cost

A sinus lift rebuilds bone height in your upper back jaw by gently lifting the maxillary sinus membrane and packing bone graft material into the space underneath. I need one when I’m placing implants in the upper back jaw and you have less than 6 to 8 mm of bone height left. The name sounds dramatic; the procedure is routine. I do them weekly.

Recovery tracks implant placement alone: about 48 hours of mild discomfort, back to a desk job at 48 hours, full activity at one week. A sinus lift is one specific answer to not having enough bone for a standard implant. When the deficit is height in the upper back jaw, this is the fix, and it’s a normal part of the implant procedure rather than a detour from it.

Because the bone above your upper back teeth disappears after the teeth are gone. The maxillary sinus is a hollow air space inside the cheekbone, sitting directly over the upper back jaw, normally separated from the jawbone by 8 to 15 mm of bone. Lose those teeth and that bone resorbs, sometimes leaving only 2 to 3 mm between gum and sinus. That’s too shallow to anchor a standard implant.

A sinus lift restores the vertical height I need to place the implant. About 1 in 5 of my upper-jaw cases needs one. It’s a height problem specifically: when the deficit is width, or it’s in the lower jaw or the front of the mouth, the right move is a standard bone graft for implants rather than a lift. I decide which on your CT scan.

Here’s the part most patients don’t hear: this is reversible biology, not a closed door. Long-term tooth loss almost never disqualifies you, it just changes the plan. If you want the full menu of options when a scan shows thin bone, I laid it out in implants with bone loss.

There are two techniques, and the gap between them is how much bone you’re short. A crestal (internal) lift goes through the implant site itself and adds a modest 2 to 4 mm at the same surgery. A lateral (window) lift opens a small window in the cheekbone to add 4 to 8 mm or more. I pick the technique from your CT scan before I ever pick up a drill.

Crestal (internal) sinus lift. Performed through the implant osteotomy. I gently push the sinus floor upward through the implant site and pack a small amount of bone graft underneath. I use it for moderate lifts (2 to 4 mm) where I can place the implant at the same surgery.

Lateral (window) sinus lift. I create a small window in the cheekbone wall to reach the sinus floor from the side, lift the membrane, pack the graft in, and close the window. This is for larger lifts (4 to 8 mm or more) where I need real volume. The implant goes in either at the same surgery, if enough of your own bone exists for stability, the kind of immediate placement behind same-day teeth, or 4 to 6 months later.

The whole decision rides on the scan. A cone-beam CT shows me the sinus floor height, the membrane, and any internal walls (septa) before I start. I plan the implant position, size, and graft volume off those millimeters, and place through a printed surgical guide that keeps me 2 to 3 mm off any nerve or artery.

Without a 3D scan you’re lifting a sinus blind. When the bone is this thin, every millimeter counts, and you never want a surgeon working blindfolded.

Easier than the name suggests. Day 1 pain is usually a 3 to 4 out of 10, about the same as implant placement alone. Most of my patients are back at a desk job at 48 hours and at full activity in a week. You may feel mild pressure in the cheek or under the eye for a few days, like a mild sinus cold, and a little bleeding from the nose on Day 1 is normal.

The one thing I’m strict about is protecting the lifted membrane while the graft sets. For two weeks: no nose-blowing, sneeze with your mouth open, no air travel, and no drinking through straws. The pressure changes those create are exactly what a freshly lifted sinus floor doesn’t need.

The graft integrates over 4 to 6 months. For lateral lifts I stage separately, I re-image at the 4-month mark to confirm the new bone volume before I place the implant, which is why a lift can push the whole implant timeline out by a few months. If you want the broader day-by-day on implant healing, my implant recovery timeline covers it, and if the part you’re really bracing for is pain, I answer that honestly on whether implants hurt.

High, and well documented. The graft itself, taking and producing enough bone to place an implant, succeeds in 95 to 97% of cases in the published literature. A systematic review of lateral-window sinus augmentation reports implant survival in grafted sinuses comparable to native bone, around 95% at 3-plus years and holding into the 10-year window.

The main thing that can happen during the lift is a perforation of the sinus membrane, the literature puts it around 10% on average, and more in tricky anatomy. When it happens to me, I repair it with a collagen membrane and the graft proceeds; the published outcomes for repaired perforations are similar to cases where the membrane stayed intact. Planning the window off the CBCT is exactly how I keep that risk low in the first place.

Once the implant is in that grafted bone, it lasts on the same terms as any other implant I place, the seal, the bite, and the maintenance. I unpack what that decade of survival actually means on my implant success rate page.

It depends on the technique. A crestal (internal) lift runs $800 to $1,500 and is often folded into the implant fee when I do it at the same surgery. A lateral (window) lift runs $2,000 to $3,500 per side, depending on graft volume and complexity. I give you the exact figure in writing at your consult, never a surprise after the fact.

Insurance varies: some PPO plans cover a sinus lift as part of the surgical fee, others exclude it entirely, and a medical PPO sometimes covers the bone graft and the CT scan. I verify your specific coverage before we plan anything.

Occasionally a CBCT shows there’s so little bone left that even a sinus lift can’t build enough height to anchor an implant in the upper back jaw. That’s the one case where I’ll talk to you about zygomatic implants, which anchor into the cheekbone and bypass the maxilla entirely, no lift required.
