Ridge Augmentation

If you are referred to our office for a tooth extraction, your dentist is anticipating that, in the future, you may get a dental implant. Following tooth removal, bone and soft tissue tend to shrink if no corrective measures or treatments are undertaken.  This can leave insufficient bone volume for subsequent implant placement, or may cause a gap between the teeth and the gum underneath a dental bridge.  In most situations, we recommend a bone graft at the time of extraction in order to preserve the bone height and width. This is done to build a solid foundation in order to prepare the site for a future dental implant.

After your tooth is carefully removed, bone graft particles are placed into the extraction site and may be covered with a resorbable and/or nonresorbable material called a membrane to hold it in place during the healing period. This bone graft material substance is called freeze-dried bone allograft (FDBA). FDBA is obtained from a donor and every vial must pass rigorous testing and the strictest guidelines of the American Association of Tissue Banks to verify that every graft is free of disease before being allowed to be used on any patient. After approximately six months of healing, your natural bone has begun to replace the grafted bone and will have improved dimensions for dental implant placement."

Under "Sinus Bone Augmentation" change the first paragraph to: "For some patients, the back area of the upper jaw is a difficult area for dental implants due to insufficient bone and the close proximity to the sinus. A sinus augmentation or lift is a procedure that corrects this problem by raising the sinus floor and developing bone in the upper back jaw to increase the vertical height."  Substitute the following for the second paragraph: "To make room for the bone, the sinus membrane has to be moved upward, or "lifted." First an incision is made in the gum to expose the bone. Then a small circle is cut into the bone, and the bone piece is lifted into the sinus cavity like a trap door. The bone graft material is added between the jaw and the maxillary sinuses, which are on either side of the nose. The bone graft material is often a substance called freeze-dried bone allografts (FDBA) which is obtained from a donor. This bone graft material substance is called freeze-dried bone allograft (FDBA). FDBA is obtained from a donor and every vial must pass rigorous testing and the strictest guidelines of the American Association of Tissue Banks to verify that every graft is free of disease before being allowed to be used on any patient. After six to nine months of healing, your natural bone has started to replace the grafted bone and your implant can be placed.
