Alveolar Bone Graft (ABG) for Children born with Cleft Lip and Palate

Some children born with a cleft lip and palate may have a gap in the gum. This gap is called an alveolar gap and may extend from near the teeth all the way up to the nose. During an ABG, a Plastic Surgeon will fill the alveolar cleft with spongy bone from the hip. The gum is carefully stitched over the bone graft to let it heal.

• The alveolus is the bone under the gums that holds the teeth. The alveolus is made of alveolar bone.
• Bone Graft is bone taken from one part of the body to another.
  

Why might an ABG be required?

One of the functions of the alveolus and gum is to hold teeth in the right place. If there is a gap in the alveolus, the teeth may grow in the wrong position which may be more difficult to treat when older.

The ABG will provide:

• Bone support for teeth to develop and grow
• Continuity and better appearance of the gum
• Better support for the base of the nose
• Closure of any fistulas (abnormal connections) between the mouth and nose

When will the ABG be done?

The best time for the ABG will be decided by a Plastic Surgeon and an Orthodontist (a Dentist who corrects the position of a person’s teeth and jaw).

• When the adult canine is ¾ developed
• Usually between nine and 14 years of age

Post-Surgery Diet

After the ABG, wounds in the mouth may make it difficult to eat. A balanced, soft diet is recommended for 6 to 8 weeks after surgery to minimise chewing and ensure adequate nutrition so the wound can heal well.
