Featured Answer: Why would I need a graft or sinus lift?
After tooth loss, the jawbone can shrink. If there isn’t enough height or width for a stable implant--especially in the upper back jaw near the sinus--a bone graft or sinus lift may be recommended to create a solid foundation and improve long-term success. At Innova Smiles in Marlborough, MA, Dr. Fatima uses CBCT 3D imaging to measure bone dimensions precisely, so MetroWest patients know exactly what to expect before any procedure begins.
Why Bone Loss Happens
Without a tooth root providing stimulation, the surrounding jawbone begins to resorb. This process starts within weeks of tooth loss and accelerates over time. Studies show that patients can lose up to 25% of bone width in the first year alone, and height loss follows in subsequent years. The longer a tooth has been missing, the more bone remodeling has occurred--which is why early evaluation matters. For patients in Northborough, Hudson, and surrounding communities who have been living with a missing tooth for months or years, grafting is often the key to unlocking implant eligibility.
What is a Bone Graft?
A bone graft is a procedure that adds bone material to your jaw to rebuild volume lost after extraction or prolonged tooth loss. The graft material acts as a scaffold, encouraging your body’s own cells to regenerate new bone over several months. Once mature, the new bone provides the density and width needed to anchor an implant securely.
Types of Bone Grafts
- Socket preservation: Performed at the time of extraction to protect the ridge shape. Graft material is placed directly into the empty socket, preserving bone width and height for a future implant. This is the most common and least invasive type.
- Ridge augmentation: Used when the ridge has already narrowed or collapsed. Additional bone material is placed to increase width and height, restoring the contour needed for both implant stability and natural-looking esthetics.
- Block graft: For more significant defects, a small block of bone (often harvested from another area of the jaw) is secured to the deficient site with tiny screws and allowed to integrate over four to six months.
- Sinus lift (sinus augmentation): Elevates the sinus membrane in the upper jaw to gain vertical height for upper molar and premolar implants. This is necessary when the sinus floor has dropped too close to where the implant needs to be placed.
Graft Material Options
Your graft may use one or a combination of these materials:
- Autograft: Bone from your own body--the gold standard for healing potential, often harvested from the chin or back of the jaw.
- Allograft: Processed donor bone from a tissue bank, widely used and well-studied for safety and effectiveness.
- Xenograft: Bone-derived material from animal sources (typically bovine), which serves as an excellent scaffold for new bone growth.
- Alloplast: Synthetic materials such as calcium phosphate ceramics that mimic natural bone structure.
When is a Sinus Lift Needed?
A sinus lift is specifically indicated for the upper back jaw (premolars and molars). The maxillary sinuses sit just above the roots of these teeth, and when a tooth is lost, the sinus floor can gradually drop into the space. If CBCT imaging shows less than 8 to 10 millimeters of bone height between the ridge crest and the sinus floor, a sinus lift is typically recommended before or during implant placement.
What to Expect During and After the Procedure
- Local anesthesia with comfort-focused protocols; sedation options are available for patients who prefer it
- The procedure itself typically takes 45 to 90 minutes depending on the type and extent of grafting
- Mild to moderate swelling and discomfort for three to five days, managed with prescribed or over-the-counter medications
- Healing time of three to six months before the implant can be placed, though simultaneous placement is sometimes possible for socket preservation grafts
- Follow-up visits to confirm readiness for the next phase using imaging

Technology That Makes a Difference
At Innova Smiles, we rely on CBCT (cone beam computed tomography) to create a three-dimensional map of your jaw before any grafting procedure. This allows Dr. Fatima to identify the exact areas of bone deficiency, measure distances to critical structures like nerves and sinuses, and plan the most conservative approach possible. If you are also exploring what to expect during implant surgery, this same imaging guides every step of the process.
Your Questions, Answered (Marlborough and MetroWest)
We will review 3D imaging, your timeline, and budget during a thorough consultation. Many patients along the I-495 corridor--from Framingham to Westborough--prefer sequencing that minimizes time off work. We coordinate grafting and implant phases to fit your schedule and maximize insurance coverage when applicable.
