Bone grafting is a surgical procedure used to reconstruct bone defects and promote the growth of new bone tissue. It’s frequently employed in dentistry, particularly for preparing the jawbone for dental implant placement.
Why Bone Grafting?
-
-
-
-
- Replacing missing bone: Missing teeth can lead to jawbone atrophy (bone loss) and reabsorption, making implant placement difficult. Bone grafting provides a solution by replacing lost bone and encouraging new bone formation.
- Creating a foundation for implants: Bone grafts help build a solid and stable base for dental implants, ensuring their successful integration and longevity.
- Restoring function and aesthetics: Bone grafting can improve jawbone shape and size, restoring proper function for chewing and speaking, as well as enhancing facial aesthetics.
- Preserving overall oral health: It can help prevent further bone loss, maintain the stability of remaining teeth, and support overall oral health.

Types of Bone Grafts:
-
-
-
-
- Alloplasts: Using synthetic materials, such as calcium phosphate derivatives.
- Xenografts: Using bone from a different species, like bovine (cow) bone.
- Autografts: Using bone from the patient’s own body (e.g., from the hip or jaw).

Bone Graft Substitutes:
These include materials like processed allograft bone (containing collagen, proteins, and growth factors), as well as graft composites made from various substances.
Bone morphogenetic proteins (BMPs) are also used to promote bone formation and healing.
Procedure and Considerations:
A dentist or oral surgeon will determine the best type of bone graft material based on individual needs.
The chosen material is placed at the graft site to encourage bone growth and integration with the surrounding jawbone.
The cost of bone grafting can vary based on factors like the type of graft material and location.
In summary, bone grafting is a valuable technique in dentistry for restoring lost bone, improving the foundation for implants, and preserving overall oral health.
