A sinus lift is a surgical procedure that increases the amount of bone in the upper jaw to allow for dental implants. It is also known as sinus augmentation, sinus elevation, sinus graft, or maxillary sinus floor augmentation.
The procedure involves raising the membrane that lines the sinuses and placing a bone graft in the space created. This bone graft fuses with the jaw bone over time. The new bone allows the placement of dental implants.
A sinus lift can be performed before or at the same time as implant placement. If the lift is done before the implants, it will need to integrate with the natural bone. This usually takes 4-9 months. During this time, new bone forms to create enough height and width for the implants.

The factors that can increase the risk of complications include:
