Some people who wish to replace their missing teeth with dental implants do not have sufficient bone in their jaw to anchor the implants firmly. They need a treatment called as Bone Grafting. In Bone grafting, either particles or a block of bone is taken from their own body or from other natural/ synthetic sources . This bone graft is fixed to the region of interest using pins to increase the bone volume to facilitate placement of implants.
What are the sources of Bone grafts?
Bone grafts may be taken from different part of your own body ( autologous) or from cadaveric bone obtained from bone banks (allograft) and from synthetic sources (alloplasts ) with similar mechanical properties to bone.
From which part of the body are the bone grafts taken?
When only a small amount of bone is needed, bone grafts are generally taken from your jaws or from your chin. When huge quantity of bone graft needed, they are usually taken from the hip region. Both of these procedures require additional surgery.
These bone grafts are fixed in position with small pins or screws that can be removed when the implants are placed.
If Bone grafts are taken from my chin or lower jaw, will I have scars on face?
No, The cut (incision) for taking the bone grafts from your chin or jaw is made on the gums inside your mouth. It is not done on the face and doesn’t leave any scar on face.
Will my face change if any bone grafts are taken from chin?
No facial changes are observed following a bone graft from chin region.
If the bone grafts are taken from cadavers, will it cause infection?
No, The bone grafts taken from a cadaver are made sterile using International standardized protocols. Hence no infections occur because of the graft.
After bone grafting procedure is performed, Will I get teeth immediately?
No, Bone grafting is a three staged procedure. You may have to wait for 6 months to 1 year for fixing your teeth.
Why should I have to wait for 6 – 12 months time?
There are two waiting periods involved in this procedure.
0 – 6 months – For your bone graft to fuse to your remaining bone to increase the volume.
6 – 12 months – For your implants to get anchored firmly in your newly formed bone.
Are there any risks involved with Bone grafting?
As with all surgery there is a risk of pain, swelling, bruising, bleeding and infection. Minimal chances of graft rejection do exist. All these complications can be avoided when proper diagnostic, sterilization and surgical protocols are followed.
