The maxillary sinuses are hollow cavities at the roof of the upper jaw bone.
Sometimes their position prevents the placement of the ideal implant without sinus grafting. Sinus grafting can be done at the time of implant placement or sometimes is needed as a separate procedure. Prior to this treatment, a CT Scan will be taken to get a three dimensional view of your jaw. This will aid in treatment planning of implant placement. Generally, a small window is made above the upper jaw which allows a bone graft to be placed into the floor of the sinus, creating the ideal site for a dental implant. Patients are made comfortable with sedation that best meets their specific situation.
