Grafting builds up bone so an implant has enough to anchor into. It is discussed when imaging shows insufficient volume, which is one reason implant quotes often cannot be finalised before a consultation: see when bone grafting is discussed. When the jaw has lost height or width, grafting rebuilds it so an implant has something solid to grip, and depending on how much is needed the graft may be placed at the time of extraction, at the time of the implant or as a separate procedure several months earlier.
Situations that lead to bone grafting for dental implants
- A tooth is being removed before an implant
- The tooth has been missing for a long time
- Prior infection or bone loss
- An upper back-tooth implant near the sinus
When grafting comes up
It is discussed when imaging shows there is not enough bone to anchor an implant securely.
- A tooth lost years ago, with the ridge since resorbed
- A tooth being removed now, where the socket will be preserved
- Upper back teeth where the sinus sits low
- A ridge too narrow for the implant width
- Bone lost through long-standing gum disease
What the plan may involve
- No graft when anatomy is adequate
- Socket preservation at extraction
- Staged ridge augmentation
- Sinus augmentation
- A different restorative plan
What the procedure involves
Grafting is usually straightforward surgery, and the significant part is the healing time afterward.
- 3D imaging to measure the deficit precisely
- Choosing the graft material appropriate to the site
- Placing the graft, sometimes with a membrane
- Healing before the implant can be placed
- Re-imaging to confirm the result before proceeding
The four kinds of graft material and how long each takes
Graft material is grouped by where it comes from. An autograft is your own bone, taken from another site, and it integrates fastest because it holds living bone cells. An allograft is human donor bone from a licensed bank, a xenograft is animal-derived bone, most often bovine or porcine, and an alloplast is a lab-made substitute such as hydroxyapatite.
Reported healing times run from about three to six months for autograft and allograft, longer for xenograft and longest for synthetic material, and most people wait three to six months after a graft before an implant is placed. Those are typical ranges, not promises: a scan and the dentist's own measurements decide when the site is ready.
Common questions
Bone Grafting for Dental Implants: questions people ask
Does the bone come from my own body?
Not usually. Several graft materials are available and the choice depends on the site and how much is needed. Ask which is proposed for you and why.
How long does it add to treatment?
It adds a healing period before the implant is placed, and the length depends on the type and extent of the graft. Ask for the expected sequence rather than a single date.
Can grafting and the implant happen together?
Sometimes, particularly for smaller deficits or socket preservation at the time of extraction. Larger reconstructions are usually staged.
Why was grafting not in the original quote?
Because it often cannot be determined until imaging is done. That is exactly why an implant quote should say what happens to the price if grafting proves necessary.
When does grafting come up before an implant?
When imaging shows there is not enough bone to anchor an implant securely. That can be a tooth lost years ago with the ridge since resorbed, or a tooth being removed now. It can be an upper back tooth where the sinus sits low, a ridge too narrow for the implant, or bone lost through long-standing gum disease.
What does grafting involve step by step?
3D imaging measures the deficit. The graft material appropriate to the site is chosen. The graft is placed, sometimes with a membrane. Healing follows, before the implant can be placed. Re-imaging confirms the result before proceeding. It is usually straightforward surgery. The significant part is the healing time.
