A large sinus lift, also known as advanced sinus augmentation, is a surgical bone grafting procedure used to significantly increase bone volume in the upper jaw before dental implant placement. This technique is essential for patients who have severe bone loss in the posterior maxilla and require substantial bone reconstruction to support stable and long-lasting dental implants.
During the procedure, the sinus membrane is carefully lifted, and a larger amount of bone graft material is placed to create sufficient bone height and density. This allows safe and predictable placement of dental implants in areas that would otherwise lack adequate bone support.
Large sinus lift surgery is commonly performed in complex implant cases and full-mouth rehabilitation treatments. Although it is a more advanced procedure compared to a small sinus lift, it provides highly reliable long-term results and significantly improves implant success rates.
