When bone grafting is required
If your jawbone isn't thick enough or is too soft, you may need bone grafting before you can proceed with dental implant surgery. That's because the powerful chewing action of your mouth exerts great pressure on your bone, and if it can't support the implant, the surgery to replace your teeth would likely be a failure. A bone graft can create a much more solid base for the implant.
With bone grafting, a piece of bone is removed from another part of your body, such as your hip, and transplanted to your jawbone. The transplanted bone will grow, but it may take six to nine months to grow enough new bone to support a dental implant. In some cases, you may need only minor bone grafting that can be done at the same time as the implant surgery. The condition of your jawbone determines how you can proceed.
