Bone Grafting for Dental Implants: Why It’s Needed and What to Expect

Been told you might need a bone graft before a dental implant? You’re far from alone. Bone grafting is a common part of implant treatment, and the idea behind it is simple: it builds up the jawbone so an implant has something solid to hold on to.

In short: bone grafting adds bone, taken from your own body, a donor, an animal source or a synthetic material, to parts of the jaw that have lost bone through tooth loss, gum disease, injury or a previous failed implant. The graft then needs time, often several months, to join with your existing bone before the implant is placed.

Key points at a glance

• Bone grafting is a surgical procedure that builds up the jawbone so it can support implants.
• Tooth loss, gum disease, trauma or a previous failed implant can all leave too little bone.
• Grafts come from your own body (autografts), a human donor (allografts), an animal source (xenografts) or synthetic materials, and each has its own advantages and considerations.
• The process runs from an initial consultation, through the procedure, to aftercare and check-ups.
• Good aftercare, including managing mild pain, gentle oral hygiene and regular check-ups, supports the graft as it integrates.
• Bone grafting carries risks, such as infection, graft failure and nerve damage.
• Costs depend on the type of graft, how complex your case is and any extra procedures, and health funds may cover part of the cost.

What is a bone graft, and why might you need one?

A bone graft is a surgical procedure that transplants bone tissue to where your jaw needs more support. In implant dentistry, it acts as a supporting framework for the implant and helps the bone regenerate, giving the implant a solid foundation.

Dental implants need healthy bone to be placed securely and stay stable over the long term. Tooth loss, gum disease and injury can all cause bone loss, which makes it harder to secure an implant. A graft builds up the existing bone to create a more stable base for it.

• A stable foundation: the graft provides the support an implant needs.
• Bone regeneration: the procedure helps regrow lost bone tissue.
• Wider use: bone grafting is also used in other areas of medicine, not just dentistry.

When is a bone graft needed for dental implants?

A graft is usually considered when there isn’t enough healthy jawbone to hold an implant. These are the most common reasons.

Tooth loss

• The longer a tooth has been missing, the more likely the jawbone in that area is to deteriorate, which can make a graft necessary before an implant.
• Long-term gaps can also affect the stability of the natural teeth next to them.

Tooth loss is common. In the 2017–18 National Study of Adult Oral Health, reported by the AIHW, 4.0% of Australian adults aged 15 and over (1 in 25) had lost all their natural teeth, rising to 21% of adults aged 75 and over. Among adults who still had some natural teeth, 10% had fewer than 21 of them.

Gum disease

• Advanced gum disease can affect the bone, and grafting may be needed to restore stability for implants.
• In some cases, grafting can also help prevent further bone loss in people with gum disease.

Injury or infection

• Accidents or severe infections can damage bone or cause bone loss, making a graft necessary before an implant.
• After facial injuries, grafting may also be used for reconstruction.

A previous implant that failed

• Not having enough bone is one cause of implant failure, and grafting can address it.
• For people trying implant treatment again, a graft can offer a more promising foundation.

If any of these sound familiar, a graft may be an important step on your way to an implant. Your dentist will confirm whether you need one.

What types of bone graft are there?

There are four main types of graft, grouped by where the bone comes from. Each has its own advantages and considerations.

Autografts

• Source: bone taken from another part of your own body, usually the hip or chin.
• Advantages: a lower risk of rejection, because the bone is your own.

Allografts

• Source: bone from a human donor, usually supplied by a bone bank.
• Advantages: no second surgical site is needed, which reduces recovery time.

Xenografts

• Source: animal bone from a tissue bank, usually from cows.
• Advantages: readily available, with no second surgical site.

Synthetic grafts

• Source: synthetic materials such as hydroxyapatite or tricalcium phosphate.
• Advantages: no risk of disease transmission, and readily available.

Weighing them up

• Compatibility: autografts offer the most compatibility but need a second surgical site.
• Availability: allografts and synthetic grafts are readily available but may cost more.
• Recovery: the type of graft can affect how long recovery takes.

Each type has pros and cons, and your dentist can explain which one suits your situation and why.

What happens during a bone graft procedure?

A bone graft follows a clear sequence: an assessment, the procedure itself under local anaesthetic, then aftercare and follow-up visits while it heals.

Before: your consultation

• Assessment: a thorough oral examination, including dental X-rays, to check whether you need a graft.
• Discussion: a detailed conversation about the types of graft available and which is most suitable for you.

During: the procedure

• Local anaesthetic numbs the area where the graft will be placed.
• If you’re having an autograft, bone is taken from the chosen area of your body.
• The graft is placed where extra bone is needed.
• It’s secured with stitches or special membranes to help it heal.

After: healing and next steps

• You’ll receive instructions for managing mild pain and swelling.
• Follow-up appointments monitor healing and prepare you for the next stage of your implant treatment.
• Every plan differs, depending on your needs and the type of graft used.
• The graft needs time to integrate with your existing bone, which can take several months.
• Once the graft has integrated, you can move ahead with the implant procedure.

Knowing each step can ease a lot of worry, and your dentist will tailor the plan to your specific needs.

How do you recover from a bone graft?

Recovery is a key part of the process, because good care helps the graft succeed and, in turn, supports your implant. Here’s what to expect.

Straight after

• Over-the-counter pain relief may be recommended for any discomfort.
• A cold compress on the area can reduce swelling.

The first week

• Stick to soft foods so you don’t put pressure on the graft site.
• Brush gently, avoiding the surgical area.

Ongoing care

• Regular check-ups monitor how the graft is healing and integrating.
• Keep up good oral hygiene to support your overall dental health.

Signs to watch for

• Unusual discomfort: pain that persists beyond the initial recovery period may need attention.
• Signs of infection: increased swelling, redness or discharge mean you should contact your dentist straight away.

Your dentist will give you an aftercare plan tailored to your needs. Once your implant is placed, our guide to dental implant recovery covers the next stage of healing.

What are the risks of bone grafting?

Bone grafting is a common procedure, but like any surgery it carries risks. Knowing them helps you make informed decisions and take sensible precautions.

Possible risks

• Infection: though rare, infection can occur after the procedure and may need further treatment.
• Graft failure: sometimes the graft doesn’t integrate well with the existing bone.
• Nerve damage: with autografts, there’s a risk of nerve damage where the bone was taken.

Complications to watch for

• Pain that continues beyond the expected healing period.
• Unusual swelling or redness, which could be a sign of infection or graft failure.
• Difficulty moving, especially if bone was taken from the hip, which may indicate a complication.

Lowering the risks

• Health checks before the procedure: being in good general health helps reduce the risk of complications.
• Following your aftercare instructions closely helps the graft integrate.
• Report any unusual symptoms to your dentist straight away.

Knowing the risks, and how to reduce them, helps you go into treatment with a clear picture.

What affects the cost of a bone graft, and can your health fund help?

The cost depends on the type of graft, how complex your case is and whether you need other procedures at the same time. Some health funds cover part of the cost, so it’s worth checking your cover before treatment, and your dentist can give you personalised advice on costs.

What affects the cost

• The type of graft: autografts may cost more because they involve a second surgical site.
• The complexity of your case.
• Any additional procedures needed alongside the graft.

Health fund cover

• Some health funds may cover part of the cost of bone grafting.
• Ask your health fund for pre-approval so you know what’s covered.
• Be prepared for out-of-pocket costs your fund may not cover.
