Raising the Sinus Floor
If bone has been lost due to injury or periodontal disease, a sinus augmentation can raise the sinus floor to allow for new bone to form.
During the procedure, the jawbone will be exposed via a small incision made near the upper premolar or molar region. An opening is cut into the bone which allows for the dentist to gently push the membrane lining the sinus upward. Bone graft material is used to fill the underlying space and the incision is closed. The graft used in this procedure can be taken from the patient’s body or from a cadaver. Synthetic materials may be used by the dentist to stimulate bone growth. Once healed, the patient may be able to get implants, though this varies case-to-case.
