Maxillary Sinus Floor Augmentation (also termed sinus lift, sinus graft, sinus augmentation or sinus procedure) is a surgical procedure which aims to increase the amount of bone in the posterior maxilla (upper jaw bone), in the area of premolar and molar teeth, by sacrificing some of the volume of the maxillary sinus.

When a natural tooth is lost, whether through dental decay, periodontal disease or dental trauma, the alveolar process begins to remodel. The edentulous (toothless) area is termed a ridge, which over time usually loses both height and width. Furthermore, the level of the floor of the maxillary sinus gradually becomes lower. Overall, this leads to a loss of volume of bone which is available for implantation of dental implants, which rely on Osseo integration.

The goal of the sinus lift is to graft extra bone into the maxillary sinus, so more bone is available to support a dental implant. Sinus augmentation (sinus lift) is performed when the floor of the sinus is too close to an area where dental implants are to be placed. This procedure is performed to ensure a secure place for the implants while protecting the sinus.

Patients who have the following may be good candidates for sinus augmentation.

Lost more than one tooth in the posterior maxilla.

Lost a significant amount of bone in the posterior maxilla.

Missing teeth due to genetics or birth defect.

Minus most of the maxillary teeth and need a strong sinus floor for multiple implants.
