Sinus Lift Surgery: Making Upper Jaw Implants Possible

A sinus lift (also called sinus augmentation) is a surgical procedure that adds bone to your upper jaw — specifically in the area of your molars and premolars — by lifting the sinus membrane and placing bone graft material in the space created.
Why Is It Needed?
When upper back teeth are lost, two things happen: (1) the jawbone beneath them begins to shrink, and (2) the maxillary sinus can expand downward into the space left by the missing teeth. This leaves very little bone height for implant placement.
The implant post needs at least 10–12mm of bone height to integrate securely. Many patients who’ve lost upper back teeth have only 4–6mm available. A sinus lift creates the additional space needed — typically adding 4–10mm of bone height — making implants possible where they otherwise couldn’t be placed.
Who needs a sinus lift? Patients missing upper molars or premolars for an extended period, or those with naturally large sinus cavities. A 3D cone beam CT scan (included in your free consultation) shows us exactly how much bone you have and whether a sinus lift is necessary.
The Sinus Lift Procedure
Both techniques are performed in-office under local anesthesia. Sedation is available for anxious patients.
3D Scan & Planning
Cone beam CT scan maps your exact sinus anatomy and bone volume — critical for safe, precise sinus lift planning.
Anesthesia
Local anesthesia numbs the area completely. IV sedation available so you feel nothing and remember nothing.
Sinus Access
A small window is created in the bone to access the sinus membrane, which is gently lifted upward.
Bone Graft Placed
Bone graft material fills the space beneath the elevated sinus membrane — building new bone height for implants.
Healing Period
New bone matures over 4–6 months before implants are placed. Follow-up scans confirm readiness.
Implant Placement
Once bone is mature, implants are placed into your newly built foundation. Success rate: 95%+.
Lateral Window (Open) Sinus Lift
A small opening in the side of the jaw gives direct access to the sinus. Best for cases requiring significant bone addition (more than 5–6mm). Highly predictable results.
Osteotome (Closed) Sinus Lift
Performed through the implant site itself — no separate incision. Best when only 1–3mm of additional bone height is needed. Faster healing, can often place implant same day.
Sinus Lift FAQ
Is a sinus lift painful?
The procedure is performed under local anesthesia — you’ll feel pressure but no pain. Post-procedure discomfort is typically mild and managed with over-the-counter pain relievers. Nasal congestion and minor swelling are normal for 1–2 weeks. Most patients return to work within 3–5 days.
How long does sinus lift healing take?
The sinus lift site needs 4–6 months to fully mature before implant placement. During healing, normal daily activities resume quickly. A follow-up cone beam CT scan confirms the new bone density and readiness for implants.
What is the success rate of sinus lift surgery?
Sinus lifts performed by trained specialists have a 95%+ success rate. Implants placed into sinus-lifted bone achieve the same long-term success rates as implants placed in native bone — typically 95–98% over 10 years.
Can I avoid a sinus lift with special implants?
In some cases, yes. Zygomatic implants anchor into the cheekbone (zygoma) rather than the jaw and can bypass the need for a sinus lift in patients with severely deficient upper jaw bone. Dr. Qiu will evaluate all options during your 3D scan consultation.
How much does a sinus lift cost?
A sinus lift typically costs $1,500–$3,500 per side, depending on the technique and amount of grafting required. Insurance may cover a portion if medically necessary. Financing is available with $0 down options.
