Sinus Lift Surgery in San Jose, CA
Patients who are missing upper back teeth may be told that a sinus lift is needed before placing dental implants. At Bay Area & Implant Center, this oral surgery gently raises the sinus floor and adds bone so implants can be placed securely. This page explains what a sinus lift is, why it is used, how the procedure works, and what to expect during recovery.
Sinus Lift Explained
A sinus lift, also called sinus augmentation, increases bone height in the upper jaw where the maxillary sinus sits low and the bone is thin. Tooth loss, gum disease, or natural anatomy can leave too little bone to support implants. During the procedure, the sinus membrane is lifted upward, and bone graft material is placed beneath it. Over time, the graft fuses with your jaw to create a stable foundation for implant placement. The goal of a sinus lift in San Jose, California, is predictable support for long-lasting dental implants.
Why Consider a Sinus Lift?
- Improves implant stability in areas with insufficient upper jaw bone.
- Helps restore chewing function by enabling reliable implant placement.
- Supports facial structure by preventing further bone collapse over time.
- Expands treatment options when alternatives are limited by bone loss.
- Offers predictable results with high success when planned carefully.
- May allow fewer staged surgeries when conditions are favorable.
How a Sinus Lift Works
The sinus lift process begins with a comprehensive exam and advanced imaging such as a CBCT scan. Imaging shows bone height, sinus shape, and membrane health. Our periodontist will review medications, sinus history, and habits like smoking, which can affect healing.
Two main techniques are used:
- Lateral window approach: A small window is created on the outer side of the upper jaw. The sinus membrane is gently lifted, and graft material is placed under it to raise the sinus floor.
- Crestal (internal) approach: Through the implant site, specialized instruments elevate the sinus floor and a smaller amount of bone graft is placed. This is suitable when only a few millimeters of lift are needed.
Graft materials can include your own bone, processed donor bone, bovine-derived grafts, or synthetic options. A thin membrane may cover the area to protect the graft. Sutures close the site. In select cases with adequate primary stability, an implant may be placed at the same time; otherwise, implants are placed after healing.
What to Expect Before and After Surgery
Before surgery, you will receive specific instructions, which may include adjusting certain medications. On the day of the procedure, local anesthesia is used, and sedation options may be available. Many sinus lifts take one to two hours depending on complexity.
After surgery, mild swelling, stuffiness, and minor bleeding are common for a few days. The sinus membrane needs time to heal, so follow these precautions:
- Do not blow your nose for at least two weeks.
- Sneeze with your mouth open to reduce pressure.
- Avoid straws, smoking, and vigorous rinsing for the initial days.
- Use prescribed medications, saline sprays, and cold compresses as directed.
Most people return to normal routines within a few days, though strenuous activity should be limited initially. A soft diet is recommended at first. Follow-up visits check healing progress. Grafted bone typically matures over four to nine months. Our periodontist will advise when it is safe to place implants. Common questions involve sinus lift recovery time, eating after surgery, and sinus lift complications; careful aftercare helps minimize issues.
