An open sinus lift is a surgical procedure used to increase bone height in the posterior upper jaw when significant bone loss prevents dental implant placement. The technique involves creating a small lateral window in the sinus wall to access and gently elevate the sinus membrane.

Bone graft material is then placed to stimulate new bone formation and provide adequate support for future dental implants. This approach is recommended when a greater amount of bone augmentation is required. Open sinus lift offers predictable, long-term results and allows safe implant placement while ensuring proper healing and patient safety.
