There are many situations in which bone grafting is necessary.

The most common situations include:

• Preparation for dental implants
• Filling defects left over when cysts have been removed from the jaws
• Bridging defects that have been created due to:
  • Removal of large cysts or tumours
  • Traumatic injuries to the face
  • Gaps created following repositioning of the jaws during orthognathic surgery
