Though traditionally bone grafts are performed based on the potential of the permanent canine to erupt, today, an important consideration is to provide bone support to the already erupted lateral incision aswell. Thus it is prudent to do the classical cancellous marrow bone graft , usually harvested from the hip at about the age of 7- 8 years.
This would allow not only the canine to erupt normally, but also provide good bone support to the lateral incisor early enough that it can withstand formal orthodontic treatment to align the teeth.
