Sinus Lift Augmentation
If the sinus cavities in your upper jaw are large, or if there is a thin wall of bone separating the sinus from the mouth, the amount of bone available for implant placement may be limited. A sinus lift augmentation may be necessary to improve bone structure and allow for the successful placement of a dental implant. During this procedure, the sinus membrane is gently lifted, and a bone graft is added to increase bone height.
If there is enough bone between the upper jaw and the bottom of the sinus to stabilize an implant, a sinus lift augmentation and implant placement may sometimes be performed in a single procedure. If there is not enough bone available, a sinus lift augmentation will be performed first, then after the graft has matured, a dental implant can be placed.
