Dental implants are inserted directly into the jaw, so your dentist needs to make sure there’s enough bone to support the implant. If you don’t have enough, it’s possible to graft bone from your other body parts, commonly your shin or hip, and insert it into the jaw.
A bone graft may be performed under local anaesthetic, or in hospital under general anaesthetic, depending on where the bone comes from. This may add some time to having your implant fitted, but can be necessary for the implant to be a success. Although this may sound intimidating, it’s a common surgery and is nothing to be worried about.
