When replacing posterior upper teeth with dental implants, one of the limiting factors is the amount of bone available between the gum and the maxillary sinus. If there is insufficient bone to allow for the placement of an implant, we may suggest a procedure called a sinus augmentation procedure or a sinus lift. During this procedure, the sinus membrane is then lifted upward and donor bone is inserted into the floor of the sinus. After several months of healing, the bone becomes part of the patient’s jaw and dental implants can be inserted and stabilized in this new sinus bone. Routine dental implant procedures can then be performed.
Sinus augmentation (sinus lift) is a surgical procedure that increases bone height in the upper jaw to support dental implants when bone has deteriorated or sinuses are too close to the jawbone.
By adding bone beneath the sinus cavity, sinus augmentation creates a stable, strong foundation for dental implants, improving long-term implant stability and reducing failure risk.
Ideal candidates have diminished upper jaw bone density, sinus proximity issues, or are preparing for dental implants in the posterior maxilla. A CT scan and exam determine eligibility.
During surgery, your dentist lifts the sinus membrane and places bone graft material into the space to encourage new bone growth. The area heals before implant placement.
Most patients experience mild discomfort after surgery, manageable with prescribed pain medication and by following post-op care instructions.
Initial healing is typically 1–2 weeks, but complete bone integration may take 4–9 months before dental implants can be placed.
As with any surgical procedure, risks include infection, sinus membrane tears, and graft failure. Your provider will discuss specific risk factors during consultation.
Bone grafts can be autogenous (your own bone), allograft (donor bone), xenograft (animal bone), or synthetic substitutes, selected based on patient needs and clinical judgment.
Cost varies by case complexity, graft material, anesthesia, and imaging needs. A personalized estimate will be provided after evaluation. For more information, contact Adam L. Bear, DDS, PLLC.
In some cases, yes. If there is adequate initial bone height and stability, implants may be placed simultaneously with the sinus lift procedure.
