Sinus Augmentation

A dental implant is essentially an artificial titanium tooth root which is placed in the jaw bone.  Eventually, a replacement tooth or bridge will be firmly fixed to this root, restoring complete function to the tooth.  The key to a successful and long-lasting implant is the quality and quantity of jawbone to which the implant will be attached.  If bone has been lost in the maxilla, or upper jaw, due to injury or periodontal disease, the maxillary sinus may enlarge or pneumonize displacing your original bone. A sinus augmentation can raise the sinus floor to allow for new bone formation.

In the most common sinus augmentation technique, an  incision is made near the upper premolar or molar region to expose the jawbone.  A small opening is cut into the bone and the membrane lining the sinus on the other side of the opening is gently pushed upward.  The underlying space is filled with bone graft material and the incision is closed.  The bone which is used for this procedure may be your own bone, or from a human or bovine donor.  Sometimes we may  use synthetic materials which can also stimulate bone formation.  The implants are placed after healing has occurred; this will depend on the individual case.  Sinus augmentation has been shown to be a very predictable procedure to  increase bone quality and quantity thereby increasing  the success of dental implant procedures.
