Corvallis Bone Grafting: Major & Minor Procedures

Types of Bone Grafting

Major Bone Grafting

Major bone grafting is essential for repairing areas with inadequate bone structure due to factors such as tooth extractions, gum disease, or injuries. Depending on the situation, graft material may be sourced from a tissue bank or harvested from the patient’s own body—commonly from the jaw, hip, or tibia. Specialized procedures, such as sinus bone grafts, are also utilized to rebuild bone in the upper jaw. Guided bone regeneration techniques may employ dissolvable membranes to protect the graft and stimulate new bone growth.

These procedures are typically performed in an operating room and may require a hospital stay. Major grafts are often necessary to address larger defects resulting from trauma, tumor removal, or congenital issues, using the patient’s own bone for the most effective restoration.

Minor Bone Grafting

Minor bone grafting is less extensive and often involves smaller areas where bone loss has occurred. This can be performed using various graft materials, including autogenous, allogenic, or xenogenic bone, as well as synthetic substitutes.

Types of Graft Materials

1. Autogenous Bone Grafts (Autografts): Sourced from the patient’s own body, these grafts contain living cells that promote healing and new bone growth. While effective, they require a second surgical site for harvesting.

2. Allogenic Bone (Allografts): Donor bone from a cadaver, processed for safety. While it cannot grow new bone independently, it serves as a scaffold for surrounding bone to grow.

3. Xenogenic Bone: Derived from another species (typically bovine), xenogenic grafts undergo extensive processing to eliminate contamination risks. Like allografts, they provide a framework for natural bone growth.

4. Bone Graft Substitutes: Synthetic materials, such as Demineralized Bone Matrix (DBM), graft composites, and Bone Morphogenetic Proteins (BMPs), offer alternatives to natural bone. These materials do not require a secondary procedure and can effectively promote bone growth.

Causes of Jaw Bone Loss

Several factors can contribute to jawbone deterioration, including:

• Tooth Extractions: Missing teeth lead to bone resorption as the jawbone no longer receives necessary stimulation.
• Periodontal Disease: Chronic gum infections can destroy the supporting bone structure.
• Unanchored Dentures: These can accelerate bone loss due to lack of stimulation.
• Facial Trauma: Injuries or fractures can halt bone stimulation and lead to loss.
• Misalignment: Uneven pressure on teeth can cause bone deterioration.
• Osteomyelitis: Bone infections require removal of infected tissue, often necessitating grafting afterward.
• Tumors: Both benign and malignant tumors may require surgical removal of bone, often followed by reconstruction.
• Developmental Deformities: Congenital issues can result in bone deficiencies that may need grafting.

The Importance of Bone Health

Teeth play a crucial role in maintaining jawbone health. When teeth are missing, the lack of stimulation leads to bone loss, which can result in various complications, including:

• Misalignment and shifting of remaining teeth
• Altered facial profile and appearance
• Difficulty speaking and eating
• Increased risk of TMJ pain and headaches
• Nutritional challenges due to chewing difficulties
