Yes. Many upper back-tooth implants in Tigard need a sinus lift first because the maxillary sinus sits just above where the implant will go. A sinus lift gently raises the sinus membrane and adds bone graft material so the implant has enough height to anchor securely. It's a routine, well-documented procedure done under local anesthesia.

At Inspire Dental, we hear the word "sinus" and watch shoulders tense. We get it. The word sounds bigger than the procedure usually is. A retired teacher from the Summerfield community came in last spring after her previous dentist told her she "didn't have enough bone" for an upper molar implant. She thought that meant no implant at all. Two appointments later, she had a clear plan, and the sinus lift turned out to be the easiest part of her treatment.

Here's what's actually happening up there, and how we decide what your jaw needs.

Why does the upper jaw sometimes need a sinus lift before an implant?

Your maxillary sinuses are two hollow, air-filled spaces sitting directly above your upper back teeth. According to the American Association of Oral and Maxillofacial Surgeons, the floor of those sinuses is the same bone that holds your upper molar roots. When you lose an upper molar, the bone in that area starts to shrink. The sinus floor can actually drop down into the space where the root used to be.

Implants need bone to grip. A dental implant is a small titanium post that anchors into the jaw, and it needs enough vertical bone height to lock in securely. If the sinus has dropped low, there isn't room for the post without entering the sinus cavity. That's where a sinus lift comes in. We add bone graft material between the sinus membrane and your jawbone, creating the height the implant needs.

That's the whole point. More bone, safer anchor.

What actually happens during a sinus lift procedure?

There are two main approaches, and the one we choose depends on how much bone you already have.

The lateral window approach is used when bone height is very low. We make a small access opening on the side of the upper jaw, gently lift the sinus membrane upward (think of carefully peeling back wallpaper), and pack bone graft material into the new space. The opening is closed and the area is left to heal.

The crestal or osteotome approach is less invasive. When you have moderate bone, we can lift the sinus floor through the same small hole prepared for the implant itself. Sometimes the implant goes in at the same visit. One appointment, done.

According to peer-reviewed implant literature, healing time between a sinus lift and implant placement typically ranges from 4 to 9 months, depending on the graft material used and how much native bone was already there. Some patients get the implant placed at the same time as the lift. Others wait. We'll tell you which group you're in before you sit in the chair.

Is a sinus lift painful or risky?

Most patients are surprised by how mild recovery is. The procedure is done under local anesthesia, and we offer sedation options for patients who want to sleep through it. Post-op, expect mild swelling for a few days and some pressure that feels a little like a head cold.

A few simple rules during healing:

• No forceful nose blowing for 1 to 2 weeks

• Sneeze with your mouth open

• Skip straws and heavy lifting for the first week

• Avoid flying right after surgery if possible

The most common complication is a small tear in the sinus membrane during the lift. The implant dentistry literature notes this is usually identified and managed during the same surgery with a collagen patch. Long-term implant survival after sinus augmentation is generally above 90% in published systematic reviews, including Cochrane reviews on bone augmentation. Those are strong numbers.

Simple as that.

How do we decide if you need a sinus lift in Tigard?

Imaging tells the truth. At our Implant Center on SW Pacific Highway, every upper implant candidate gets a 3D cone beam CT scan. The American Academy of Oral and Maxillofacial Radiology recognizes CBCT as the standard for evaluating maxillary bone height before implant placement, and for good reason. A flat X-ray can't measure the third dimension. A cone beam can, down to the millimeter.

Here's roughly how the numbers play out:

• Under 5mm of bone height: a lateral window sinus lift, then implant later

• 5 to 8mm: often a crestal lift with simultaneous implant placement

• Over 8mm: no lift usually needed

We also review your sinus history. Chronic sinusitis, allergies, or recent infections don't disqualify you, but they change timing. If you commute up 99W from Tualatin or Sherwood and deal with Willamette Valley pollen season every spring, we'll plan around that.

For our Bull Mountain and King City patients who've been told elsewhere that implants weren't an option, the consultation is often the moment things change. Bone you don't have can be built. The technology is solid, the science is published, and we've done this many, many times.

Frequently Asked Questions

How long after a sinus lift can I get my dental implant?

If the lift and implant happen together, you skip this step entirely. If they're staged, most patients wait 4 to 9 months for the graft to mature into solid bone. We confirm readiness with a follow-up cone beam scan before placing the implant, so we're never guessing.

Will a sinus lift change how my sinuses feel or function?

No. The sinus membrane is lifted, not removed, and your sinus cavity simply becomes slightly smaller. Patients don't report changes in breathing, smell, or sinus drainage long-term. You may feel some short-term pressure or congestion in the first week, similar to a mild cold.

Can I fly on an airplane after a sinus lift?

We recommend avoiding air travel for at least 2 to 3 weeks after surgery. Cabin pressure changes can stress the healing sinus membrane. If you have a trip planned, tell us at the consultation and we'll time the procedure around it.

What kind of bone graft material is used in a sinus lift?

We typically use a combination of processed bone graft material that your body gradually replaces with your own bone over several months. Options include human donor bone, bovine-derived mineral, and synthetic materials. We'll walk you through which makes sense for your case and your preferences.

Does dental insurance cover a sinus lift?

It depends on your plan. Some dental plans cover a portion of the bone graft and sinus lift; others classify them as elective. Medical insurance occasionally contributes when there's a documented medical reason. Our front office reviews your benefits before you commit to anything, so the numbers are clear up front.

If you've been told you don't have enough bone for an upper implant, that's not the end of the conversation. It's the start of one.
