A surgical procedure (bone graft) that increases the amount of bone in the posterior maxilla (upper jaw). It is the broader category that includes the specific "Sinus Lift" technique.

Why It Matters

When upper back teeth are lost, the maxillary sinus (air cavity) expands downwards (pneumatization), leaving paper-thin bone. Augmentation restores the height needed to screw in an implant.

Clinical Details

• Materials: Xenograft (bovine bone) is most common due to its slow resorption rate, providing stable volume.
