Before a builder pours concrete or a gardener plants a seed, the ground must be studied. Its composition, its strength, and its readiness to hold what’s to come all determine the outcome. A solid foundation, whether made of earth or intention, gives support to things that last. The same idea applies in dentistry. Before placing an implant, we make sure the jaw has the support it needs. Sometimes that means performing a sinus lift to prepare the upper jaw for the implant. It’s a simple step that reinforces the foundation, creating the conditions for something lasting to take shape. Because every great result begins where no one’s looking: at the foundation that holds it all together.
What Is a Sinus Lift?
When you’re missing teeth in the upper back part of your jaw, placing dental implants isn’t always straightforward. This area sits just below the sinus cavity, and if there isn’t enough bone to support an implant, we may recommend a sinus lift.
A sinus lift is a specialized bone grafting procedure that creates the space needed for a secure implant. Dr. Aaron begins by making a small opening in the gum and jawbone. They then gently elevate the sinus membrane to create space for bone graft material. Once the graft is in place, the area is closed and left to heal. Over time, your body builds new bone in this area, creating the solid foundation needed for implant placement. Depending on your bone structure, the implant may be placed during the same procedure or after the graft has fully healed.
Two Techniques, One Goal: Building a Stronger Foundation
There are two main types of sinus lift procedures: direct and indirect. Each approach is designed to increase the amount of bone available for a dental implant.
- Direct sinus lift: This method is used when more extensive bone grafting is needed. Dr. Aaron creates a small opening on the side of the upper jaw to access the sinus directly. After lifting the membrane, bone graft material is placed into the space. This technique allows for a significant increase in bone height, making it ideal for patients with limited existing bone.
- Indirect sinus lift: A less invasive option, the osteotome method is used when only a modest lift is required. Instead of creating a side window, Dr. Aaron accesses the sinus floor at the same site where he places the implant. Special tools called osteotomes gently push the sinus membrane upward from below. This method is typically quicker and requires less recovery time, but it is only suitable when there is already enough bone to support the initial lift.
Do I Need a Sinus Lift? 
Dr. Aaron begins the evaluation process with advanced imaging, such as cone beam computed tomography (CBCT). This technology provides a 3D view of the upper jaw, allowing precise measurement of bone height and a clear look at how the sinus cavity relates to the planned implant site. If the bone is too thin or the sinus sits too low, a sinus lift may be necessary to prepare the area for implant placement.
Several common conditions can lead to reduced bone in the upper jaw:
Bone Shrinkage After Tooth Loss
After a tooth is gone, the surrounding bone begins to break down. This process, known as resorption, occurs because the jaw no longer receives the stimulation it once got from the tooth root. Without regular stress from chewing, the bone gradually becomes thinner and shorter. Over time, this loss may leave insufficient bone to anchor an implant.
Damage From Periodontal Disease
Chronic gum disease affects the soft tissues in your mouth and also compromises the underlying bone. Periodontitis causes ongoing inflammation, which can weaken or destroy the jawbone around natural teeth. Even after treatment, the bone may not recover enough to support a dental implant. A sinus lift allows Dr. Aaron to regenerate bone in that area and restore the structure needed for long-term stability.
Previous Injury to the Jaw
Trauma to the upper jaw, whether from an accident or prior surgical treatment, can leave the bone compromised. Fractures or other structural damage may reduce bone volume or alter the shape of the sinus floor. In these cases, Dr. Aaron evaluates the extent of the damage and may recommend a sinus lift to prepare the area for future implant placement.
