A sinus lift — also called a sinus augmentation — is a specialized bone graft procedure that adds bone to the upper jaw in the area of the molars and premolars. The natural bone in this area is often thin, and after tooth loss it becomes too shallow to support dental implants. A sinus lift creates the bone volume needed for successful implant placement in the upper back jaw.
Why a Sinus Lift Is Needed
The maxillary sinuses are large, hollow air spaces located above your upper back teeth, on either side of your nose. The thin bone separating the roots of these teeth from the sinus floor is called the sinus floor.
Several factors can leave inadequate bone height in this area: natural anatomy (some patients simply have very thin sinus floor bone to begin with), tooth loss (when upper back teeth are lost, the bone shrinks and the sinus expands downward over time), gum disease (periodontal disease can destroy bone in this region), and trauma. The result is often only 1–4 mm of bone — far less than the 8–10 mm typically needed for a standard dental implant.
A sinus lift solves this problem by gently raising the sinus membrane and placing bone graft material between the membrane and the existing bone. Over several months, the graft integrates and creates the bone volume needed for successful implant placement.
Lateral vs. Crestal Sinus Lift
Two main techniques are used for sinus lifts, chosen based on how much bone needs to be added.
The lateral window technique is used when significant bone augmentation is needed (typically when less than 4 mm of native bone exists). A small window is created in the side wall of the sinus, the membrane is gently elevated, and graft material is placed underneath. This is the most common technique for major sinus lifts.
The crestal (osteotome) technique is used when only a modest amount of bone is needed (typically when 5–7 mm of native bone exists). A small opening is made through the implant site, the sinus floor is gently raised through this opening, and graft material is placed. This technique is less invasive but only works for smaller augmentations.
Some cases allow simultaneous sinus lift and implant placement; others require the sinus lift first, with implant placement 4–9 months later after the graft has matured. We use 3D imaging to plan each case and determine the optimal approach.
What to Expect During the Procedure
- 1
Consultation and 3D imaging
A cone beam CT scan provides detailed 3D imaging of your sinus, existing bone, and surrounding anatomy. This is essential for planning a successful sinus lift.
- 2
Anesthesia
The procedure is performed under local anesthesia, typically with sedation for comfort. You will feel pressure but no pain.
- 3
Access and elevation
Depending on the technique chosen, the sinus is accessed either through a small lateral window or through the implant site. The thin sinus membrane is carefully elevated using specialized instruments.
- 4
Graft placement
Bone graft material is gently packed into the space created beneath the elevated sinus membrane. The graft material acts as a scaffold for new bone to form.
- 5
Closure and healing
The site is closed with sutures and protected during healing. Over 4–9 months, the graft integrates and forms new bone capable of supporting dental implants.
Recovery and Aftercare
Recovery from a sinus lift is typically straightforward. Most patients experience moderate swelling and mild discomfort for 3–7 days, well-managed with prescribed medication. Some minor bleeding from the nose on the affected side is common in the first day or two and is normal.
Critical post-operative instructions include avoiding nose-blowing for at least two weeks (which can disrupt the graft and sinus membrane), sneezing with the mouth open (to avoid pressure changes in the sinus), avoiding straws and smoking, and taking any prescribed antibiotics as directed. We provide complete written instructions and remain available for any questions during recovery.
Most patients return to normal activities within a few days, with full recovery taking 2–3 weeks. The graft continues to integrate over the following months, and we monitor with periodic imaging.
Why This Procedure Requires Specialists
Sinus lifts are advanced procedures that require specialized training, sophisticated imaging, and significant experience to perform safely and predictably. Complications — sinus membrane perforation, sinus infection, graft failure — are uncommon when the procedure is performed by experienced specialists, but they can occur. For this reason, sinus lifts at Gateway Smiles are typically performed by trusted oral surgeons or periodontists who specialize in advanced implant procedures. We coordinate the entire treatment plan, refer to the specialist for the surgical phase, and complete the implant restoration ourselves once the graft has healed and implants are placed.
Cost and Insurance
Sinus lift procedures typically cost $1,500–$3,500 depending on the size of the graft and the technique used. This is in addition to the cost of subsequent implant placement. Some dental insurance plans cover a portion of bone augmentation procedures when documented as medically necessary for tooth replacement. We help with insurance navigation and provide clear written estimates before treatment.

The procedure itself is performed under local anesthesia and sedation and is not painful. Recovery typically involves mild to moderate discomfort and swelling for several days, well-managed with prescribed medication. Most patients are surprised by how comfortable the recovery is.
From sinus lift to final implant restoration, the typical timeline is 8–12 months. The sinus lift heals for 4–9 months, then implants are placed and integrate for another 3–6 months, and then the final crown or bridge is fabricated and placed.
For approximately two weeks after the procedure, you should avoid nose-blowing, sneeze with your mouth open, avoid straws, avoid smoking, and avoid air travel if possible. These precautions prevent pressure changes that could disrupt the graft and sinus membrane during healing.
Small perforations of the sinus membrane occur in approximately 5–10% of sinus lifts and are typically managed without affecting the outcome — the surgeon places a small membrane patch over the perforation and continues. Larger perforations may require postponing the graft to a future appointment. Experienced surgeons handle this routinely.
Sinus infection after a sinus lift is uncommon (less than 5% of cases) and is typically prevented by appropriate antibiotics and post-operative care. If a sinus infection does develop, it is usually treated successfully with additional antibiotics. Pre-existing sinus conditions should be addressed before sinus lift surgery.
In some cases, shorter implants can be used in the upper back jaw without a sinus lift. Other alternatives include zygomatic implants (longer implants anchored in the cheekbone) for severe cases, or replacing missing teeth with a bridge supported by other teeth instead of an implant. Each option has trade-offs that we discuss at consultation.
