Alveolar Bone Grafting (SABG)
What is Secondary alveolar bone grafting?
Secondary alveolar bone grafting is a technique in which bone is grafted into the cleft site inside the jaws. The bone is most commonly taken from the iliac or hip bone.
Why is secondary alveolar bone grafting done?
The primary aim of any cleft-related surgery is to restore proper function of the patient with respect to occlusion. The eruption of teeth in proper order and chronology is an important factor. In cleft patients due to the presence of the cleft over the alveolus, the teeth in the vicinity of the cleft fail to erupt. It is required to fill up the gap in the bone so that teeth
can erupt into the new bone. Also, it helps raise the base of the all of the nose and assists in Rhinoplasty
When is alveolar bone grafting done?
secondary alveolar bone grafting should be ideally timed somewhere between 6-7 years of age and prior to the eruption of teeth in the cleft region..
The main aims of the treatment are :
The form & Function should be restored
Proper occlusal relationship of the maxilla and mandible must be created & maintained.
The eruption of the tooth in the vicinity of the cleft should be stimulated.
An arch form should improve as well.
