Bone Grafting Procedures: Repair inadequate bone due to tooth loss, gum disease, injuries and tumors.
Information about the growth factors we can use to rebuild bone in many situations, ask us about these new procedures that are more predictable and less invasive
Over a period of time, the jawbone associated with missing teeth atrophies is reabsorbed. This often leaves a condition in which there is poor quality and quantity of bone suitable for placement of dental implants. In these situations, most patients are not candidates for placement of dental implants.
Today, we have the ability to grow bone where needed. This not only gives us the opportunity to place implants of proper length and width, it also gives us a chance to restore functionality and esthetic appearance.
In severe cases, the ridge has been reabsorbed and a bone graft is placed to increase ridge height and/or width. This is a technique used to restore the lost bone dimension when the jaw ridge gets too thin to place conventional implants. In this procedure, the bony ridge of the jaw is literally expanded by mechanical means. Bone graft material can be placed and matured for a few months before placing the implant.
Socket preservation is a form of bone grafting that is done at the time your tooth is extracted. There are a number of reasons that we could recommend filling the “socket” with bone when it is extracted.
One of the most common reasons is to regrow the bone that is lost to maintain enough bone volume so that if you want to replace the tooth with an implant at a later date we have built the foundation.
It is one of the most cost effective and predictable procedures used to preserve and grow bone when a tooth is lost.
Commonly “preserving” the socket after extraction will also protect the adjacent teeth from bone loss.
Ask Dr Baldassarre if you are a candidate for this procedure

Bone Grafts to Save Your Teeth
Techniques to preserve your gums and bone are used today in many situations. Gum disease has traditionally been treated by eliminating the gum pockets by trimming away the infected gum tissue and by re-contouring the uneven bone tissue. Although this is still an effective way of treating gum disease, new and more sophisticated procedures are used routinely today. One of these advancements is guided bone regeneration, also referred to as guided tissue regeneration. This procedure is used to stabilize endangered teeth or to prepare the jaw for dental implants.
As periodontal disease progresses, pockets of degenerated bone develop in the jaw. These pockets can promote the growth of bacteria and the spread of infection. To address these pockets, Dr. Baldassarre may recommend tissue regeneration. During this surgical procedure, the pockets are cleaned thoroughly, gel like growth factors and a membrane is installed between the soft tissue and the pocket in the bone. Some of these membranes are bio-absorbable and some require removal. The membrane covers the pocket so that fast-growing soft tissue is blocked, and slower-growing bone can begin to grow, or regenerate itself.
The effectiveness of the procedure generally depends on the patients willingness to follow a strict postoperative diet and careful oral care. Dr. Baldassarre will help you determine if bone regeneration surgery is right for you.
Major Bone Grafting
Bone grafting can repair implant sites with inadequate bone structure due to previous extractions, gum disease, or injuries. The bone is either obtained from a tissue bank or your own bone is taken from the jaw, hip, or tibia (below the knee.) Sinus bone grafts are also performed to replace bone in the posterior upper jaw. In addition, special membranes may be utilized that dissolve under the gum and protect the bone graft and encourage bone regeneration. This is called guided bone regeneration or guided tissue regeneration.
Major bone grafts are typically performed to repair defects of the jaws. These defects may arise as a result of traumatic injuries, tumor surgery, or congenital defects. Large defects are repaired using the patients own bone. This bone is harvested from a number of different sites depending on the size of the defect. The skull (cranium), hip (iliac crest), and lateral knee (tibia) are common donor sites. These procedures are routinely performed in an operating room and require a hospital stay
