When you've lost upper back teeth, the maxillary sinus naturally expands downward into the space where teeth once were. This bone loss prevents safe implant placement. Our sinus lift procedure restores the bone height you need, enabling successful dental implants where they're most needed. With sedation options and expert surgical technique, we achieve a 95%+ success rate.
The maxillary sinus sits directly above the roots of your upper back teeth. In a healthy jaw, the sinus floor typically sits 10-15mm above the tooth roots. After tooth loss, the sinus expands downward as bone resorbs, sometimes leaving just 2-3mm of bone—far too little for a standard dental implant.
A sinus lift (sinus augmentation) raises the sinus membrane upward and places bone graft material underneath. This creates the foundation needed for implants to integrate securely. Our surgical team uses advanced 3D imaging and careful technique to safely lift the sinus membrane without perforation, ensuring optimal bone augmentation for long-term implant success.
Sedation options to ensure your comfort throughout surgery
Lateral Window Technique: Used for significant bone augmentation needs. We create a small window in the lateral wall of the maxillary sinus, gently lift the sinus membrane, and place bone graft material in the created space. This technique allows for substantial height gain—often 8-10mm or more. The procedure typically takes 1-2 hours and requires 4-6 months of healing before implant placement.
Internal/Crestal Approach: Ideal for minor augmentation needs (3-5mm of additional height). The sinus membrane is lifted through the implant site itself, making it minimally invasive with a shorter recovery period. In many cases, the implant can be placed simultaneously, with healing occurring around the integrated implant. Your surgeon will recommend the best approach based on your 3D imaging results and the amount of bone augmentation needed.

A comprehensive walkthrough of the sinus lift procedure
Local anesthesia is administered and your chosen sedation option is initiated. Vital signs are continuously monitored throughout the procedure.
For lateral window approach: a small window is carefully created in the lateral sinus wall. For internal approach: access is made through the implant site.
The sinus membrane (Schneiderian membrane) is gently lifted away from the sinus floor using specialized instruments. Extreme care is taken to prevent perforation.
Bone graft material is carefully packed into the space created beneath the elevated membrane, building the height needed for future implant placement.
The surgical site is closed with sutures. For the lateral window technique, a membrane covers the window opening. You'll be monitored in recovery before discharge with detailed post-operative instructions.
Some swelling, discomfort, and minor bleeding are normal during the first week. Ice packs, prescribed pain medications, and rest will help manage symptoms. Avoid strenuous activity, heavy lifting, and blowing your nose forcefully.
Swelling gradually decreases over weeks 2-4. Continue prescribed medications and maintain excellent oral hygiene while being gentle around the surgical site. Follow all dietary restrictions—stick to soft, cool foods and avoid hot beverages.
Bone graft material integrates with your natural bone over 4-6 months. Regular follow-up appointments monitor healing progress. Once fully healed and confirmed by imaging, implant placement can proceed with confidence.
Sinus lift surgery transforms the upper jaw, making dental implants possible in areas previously thought impossible. After successful augmentation, you gain the bone height and volume needed for secure, long-lasting implants.
This restoration brings back the stability, functionality, and aesthetics of a complete smile. Many patients report improved eating ability, enhanced speech clarity, and renewed confidence in their appearance. With a 95%+ success rate and decades of clinical research supporting the procedure, sinus lift surgery is a proven pathway to a complete, healthy smile.
