Sinus Augmentation

This procedure is applied when periodontists find it difficult to implant dentures or bridges. Traditionally, the back of the upper jaw is the most difficult place to perform dental implants. That's where the sinus augmentation procedure is performed. In this procedure, the sinus floor along with the developing bone is raised to secure dental implants properly.

A sinus augmentation may be an appropriate oral surgery if you want to replace teeth with dental implants because you are:

  • Missing more than one tooth in the back of the upper jaw
  • Missing a large amount of bone in the back of the upper jaw
  • Missing teeth due a congenital (present at birth) defect or condition
  • Missing most of the teeth in the upper jaw and need firm anchorage for multiple implants

A bone graft procedure can help achieve the bone height required by dental implants.

During sinus augmentation surgery

There are many ways for a surgeon to perform a sinus augmentation. In one of the most common ways, the oral-maxillofacial surgeon makes an incision in the gum and gently pulls the gum tissue back. The surgeon then cuts into the gum area to expose the sinus membrane. The membrane is then lifted from the bony sinus floor to manufacture a space for bone graft material. The bone graft material is then placed in the space to help the body grow bone and form a thicker sinus floor.

Once the bone graft site has healed, the jaw bone below the sinus may be prepared for a dental implant or other dental restoration.

A sinus augmentation is generally performed in the dental office under local anesthesia. Some patients also may request oral or intravenous sedative medication as well.

After sinus augmentation surgery

Treatment results are specific to each individual patient, so they may vary from person to person. The entire process, from tooth extraction to final dental implant placement, may take up to a year.

Your surgeon will have a specific recovery plan for you to follow after your procedure. To maximize your potential for a successful outcome, you must carefully follow your recovery plan.
