Advanced Bone Grafting Surgery
When upper jaw bone is insufficient for dental implants, sinus lift grafting elevates your sinus and builds bone foundation. Our surgical team specializes in lateral window and crestal approaches for optimal outcomes.
Dr. Tocchio and our dental anaesthetist select the optimal technique based on your anatomy, available bone height, and implant timeline
Lateral Window Approach
The most common and predictable sinus lift technique. We create a small window in the lateral wall of the maxillary sinus, carefully elevate the sinus membrane, and pack bone graft material beneath it. This approach provides excellent visualization and control, ideal for cases requiring significant vertical bone gain.
Learn MoreCrestal (Osteotome) Approach
A less invasive technique performed through the tooth socket or planned implant site. Using specialized instruments, we gently elevate the sinus membrane and place bone graft from above. This approach works well when 4-6mm of bone is already present and can often be combined with immediate implant placement.

For complex cases, we use both techniques. The lateral window provides excellent visualization and grafting of posterior areas, while the crestal approach accesses anterior regions. This hybrid method maximizes bone gain across the entire sinus floor for comprehensive reconstruction.
Learn MoreThe Sinus Lift Procedure
CBCT imaging shows the exact height and density of bone available in the posterior upper jaw, and the precise position of the sinus membrane.
We measure the bone gap from the implant placement site to the sinus floor, determining how much bone height needs to be gained.
Advanced imaging allows us to identify any sinus inflammation or disease that must be treated before graft placement.
This detailed pre-operative planning is essential to successful sinus lift outcomes and allows us to estimate healing time and implant placement timing.
Dr. Singh creates a small window in the lateral sinus wall, accessing the sinus membrane without entering the nasal cavity.
The membrane is gently elevated (lifted) upward, creating space beneath it for bone graft placement.
Precise surgical technique prevents membrane perforation, which could compromise graft success and require repeat surgery.
The sinus floor is now positioned higher, effectively gaining vertical bone height in the area where the implant will be placed.
A biocompatible bone graft (often a combination of your own bone and donor material) fills the space created beneath the elevated sinus membrane.
Our in-house CAD/CAM lab allows us to prepare customized graft mixtures optimized for your specific anatomy and healing requirements.
The graft serves as a scaffold for your body's own bone cells to populate, eventually creating new living bone in the sinus cavity.
Proper graft placement and stabilization are critical to ensuring new bone forms at the correct height and density for implant support.
The surgical site is closed with sutures, and the sinus membrane seals naturally over the next few days.
Bone formation begins immediately as your body recognizes the graft and starts populating it with new bone cells.
Over 4-6 months, the graft matures and integrates with your natural bone, creating a solid foundation for implant placement.
Follow-up CBCT imaging at 4-6 months verifies that adequate bone height has been gained for safe implant placement.
Once the grafted bone has matured and integrated with your natural bone, the implant is precisely placed within the new bone volume.
Computer-guided surgery ensures the implant is positioned in the optimal location within the newly created bone, ensuring maximum support and esthetics.
With adequate bone height and density achieved through the sinus lift, the implant has excellent primary stability and high osseointegration success rates.
Following osseointegration, a beautiful custom crown or bridge is fabricated and attached, restoring your smile and chewing function permanently.
Bone Graft Materials We Use
At Vitality Dental, we offer multiple bone grafting options to suit your clinical needs and preferences:
Autologous (Your Own Bone): The gold standard—we harvest bone from your chin or jaw and use it to graft the sinus. It's entirely biocompatible with zero rejection risk. Ideal for patients willing to undergo dual-site surgery.
Allograft (Cadaverous Human Bone): Sterilized, processed human bone from tissue banks. Excellent integration, no donor site morbidity, and consistent availability. FDA-approved and widely successful.
Xenograft (Animal-Derived): Bovine or porcine bone undergoes demineralization and processing to match human bone properties. Provides excellent scaffold support and integrates predictably.
Synthetic (Bone Substitute): Lab-engineered materials mimicking natural bone chemistry. Fully resorbed as your body's bone forms, eliminating foreign material long-term.
Combination Approach: Often the most predictable. We layer your own bone with allograft or xenograft, maximizing biology while extending graft volume. Dr. Tocchio and our dental anaesthetist select the optimal combination based on your anatomy and goals.
Everything you need to know about the procedure, recovery, and timeline
The procedure typically takes 1-2 hours depending on complexity, the approach used, and whether it's combined with implant placement. Lateral window approaches usually take longer than crestal techniques. Your anesthesiologist will keep you comfortable throughout.
Most patients experience minimal pain—discomfort is usually well-managed with prescribed medication for 3-5 days. Swelling peaks around day 2-3 and gradually resolves over 1-2 weeks. We provide detailed post-op instructions to minimize complications and ensure smooth healing.
Sinus membrane perforation occurs in 10-30% of cases but is not a failure—it's expected and managed. If detected during surgery, we repair it with a barrier membrane and proceed. Studies show perforation doesn't significantly impact graft success rates when properly managed.
On average, patients gain 4-12mm of additional bone height in the grafted area. The amount depends on graft volume, technique, and healing response. Dr. Tocchio and our dental anaesthetist aim for 10-12mm minimum to accommodate a standard-length implant comfortably.
Implants are typically placed 4-6 months after sinus lift, allowing the graft to mature into solid bone. Some cases (especially with autologous bone) may allow earlier placement at 3-4 months. In select situations with sufficient new bone, implants can be placed immediately or after 2-3 months.
Avoid strenuous exercise, heavy lifting, and bending for 7-10 days post-surgery. Don't blow your nose forcefully for 2 weeks. Gentle nasal saline rinses begin day 3-5. Soft diet for the first week, gradually progressing to normal. You can return to desk work within 3-5 days.
