Major & Minor Bone Grafting

Over a period of time, the jawbone associated with missing teeth atrophies or is reabsorbed. This often leaves a condition in which there are 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 aesthetic appearance.

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.

The Importance of Teeth for Jaw Bone Health:

When teeth are missing, the jawbone can start to deteriorate, causing various issues. Without stimulation from chewing and biting, the jawbone can weaken and shrink. This can lead to pain, difficulty eating and speaking, and changes in facial appearance.

Consequences of Tooth and Jawbone Loss:

  • Problems with remaining teeth, such as misalignment and loosening
  • Changes in facial profile and lip support
  • Increased risk of jaw pain, headaches, and difficulty speaking
  • Challenges with nutrition due to chewing issues
  • Potential sinus expansion and other facial distortions.

Common Causes of Jawbone Loss:

  1. Tooth Extractions: When a tooth is removed without replacement, the jawbone may deteriorate due to lack of stimulation from chewing and biting.

  2. Periodontal Disease: Infections gradually destroy gum support and bone, leading to tooth loss and bone deterioration.

  3. Dentures/Bridgework: Unanchored dentures or bridges can cause bone loss over time as they don’t stimulate the underlying bone.

  4. Trauma: Injuries resulting in tooth loss or damage can halt bone stimulation, leading to bone loss.

  5. Misalignment: Teeth misalignment or abnormal forces during chewing can cause bone deterioration.

  6. Osteomyelitis: Bacterial infection in the bone can reduce blood supply and lead to bone loss.

  7. Tumors: Benign or malignant tumors may require removal of jaw portions, necessitating reconstructive bone grafting.

  8. Developmental Deformities: Birth defects may result in missing portions of the jaw, requiring bone grafting for restoration.

  9. Sinus Deficiencies: Tooth removal in the upper jaw can lead to sinus enlargement and bone loss, which may require a sinus lift procedure for treatment.

 What is Bone Grafting?

Bone grafts are typically performed to repair defects in the jawbones. These defects may happen as a result of traumatic injuries, tumor surgery, or congenital defects. This also helps to secure a proper placement for a dental implant. Where the bone needs a large repair, an oral surgeon would use the patient’s 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.

Types of Bone Grafts:

Autogenous Bone Grafts: Harvested from your own bone, typically from the chin, jaw, leg, hip, or skull. Contains live bone cells to enhance growth. Requires a second procedure but offers excellent compatibility.

Allogenic Bone: Harvested from a cadaver, processed to remove water. Serves as a scaffold for surrounding bone growth. Doesn’t regenerate bone but eliminates the need for a second procedure.

Xenogenic Bone: Derived from another species, often cow bone. Processed to avoid rejection. Acts as a framework for bone growth without requiring a second procedure.

Bone Graft Substitutes:

Demineralized Bone Matrix (DBM)/DFDBA: Extracted from allograft bone, containing proteins and growth factors. Available in various forms for easy application.

Graft Composites: Mixtures of different graft materials and growth factors, offering versatility. Examples include collagen/ceramic composites and DBM combined with bone marrow cells.

Bone Morphogenetic Proteins (BMPs): Naturally occurring proteins that promote bone formation and healing.

Synthetic materials offer the advantage of avoiding a second procedure. Drs. Miremadi and Hong will help determine the best option for you.
