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 CAT Scan will be taken in the office of Raleigh Periodontics 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.
