What is it?
Bone grafting is a surgical procedure that establishes support for a dental implant by replacing missing jaw bone from the opening created by an extracted or removed tooth.
When a tooth has been removed or extracted, the extracted root creates an opening.
Consequently, the supporting bone underneath gradually collapses, and bone becomes lost. Forty percent of the original amount of bone may be lost in as little as six months and will continue to deteriorate with time.
When bone-loss reaches a level where dental implants are not possible, bone grafting is used to rebuild bone for anchoring a dental implant or replacement tooth.
How is it done?
- The gums are cut in order to make a flap.
- This flap is pulled back in order to expose the bone underneath.
- A bone substitute is placed to fill the areas of bone loss. Materials include: synthetic bone, animal bone (cow), donated bone, and your own bone.
- A membrane is then used to cover the area, prevent the gums from growing into the spaces, and keep the shape of the new bone.
- The flap is placed back to cover the area and stitched into place.
- The membrane will resorb with time and depending on the type of bone graft used, the bone should mature within 6 to 10 weeks.
Once the graft is placed, your body will remove the fill in the area with its own new bone, resulting in bone regeneration and a strong foundation for a replacement tooth. With successful bone regeneration, normal spacing between teeth and the attached gum tissue will also be restored.
