What is bone grafting and do you need it before dental implants?

You may have heard that some people need a bone graft before getting a dental implant. But what does it actually mean and are you likely to need one?

The good news is that bone grafting is a well-established and routine procedure. It’s helped millions of people successfully receive dental implants. While it does add an extra step to the treatment process, it means that you’ll have the best possible long-term results.

Whether you need bone grafting depends on your individual oral health and the current condition of your jawbone. A thorough assessment will determine if this is needed in your specific case.

What is a Bone Graft?

This dental procedure adds bone material to your jaw. The idea is to strengthen the jaw and rebuild it. This creates a stable, solid foundation for dental implants. Think of it as laying a strong foundation before building a house. The graft means your jawbone can properly support the implant.

Bone material is carefully placed in areas where your natural bone has been lost or is insufficient. This acts like a scaffold. It encourages your body to grow new, healthy bone tissue. Over time, the graft material integrates with your existing bone. It gives you a stronger, denser jawbone structure.

The bone grafting process stimulates your body’s natural healing response. It promotes the growth of new bone cells. This is called osseointegration and is the same mechanism that allows dental implants to fuse permanently with your jawbone.

There are several types of bone grafts. Each is designed for different situations and patient needs. Your dentist will recommend the most appropriate type based on your circumstances. This includes looking at the implant site’s location and the amount of bone regeneration that’s required.

Why is a Bone Graft Sometimes Necessary?

Dental implants need a solid base. A jawbone that’s too thin or soft, or if it has insufficient volume, won’t work. This is because the implant may not fuse properly with the bone.

When you lose a tooth, the surrounding jawbone begins to deteriorate (a process called bone resorption). This is because it no longer receives stimulation from the tooth root.

Both the height and width of the bone can reduce, often significantly. Without adequate bone structure, there simply isn’t enough to support a dental implant. Bone grafting gives you enough dense bone for a successful implant. 

The procedure also helps maintain the natural contours of your face and jaw. Bone loss can lead to a sunken appearance around the mouth. Bone grafting helps preserve facial structures so you maintain a more youthful appearance.

Additionally, adequate bone volume is crucial for proper implant positioning. Without sufficient bone, the implant might need to be placed at an awkward angle or in a less-than-ideal position. This could affect both function and aesthetics. Bone grafting means you can place the implant in an optimal location for the best outcome.

What a Bone Graft Involves

It’s typically done under local anaesthetic to make it comfortable and pain-free. Depending on the extent of the grafting needed, some patients may also receive sedation to help them feel more relaxed throughout the procedure.

Type of Bone Material Used

There are several types of bone materials used in bone grafting for dental implants:

• Synthetic bone material. This is a bone substitute created in a laboratory. This is biocompatible and encourages natural bone growth. These materials are completely safe and eliminate any risk of disease transmission.
• Donor bone. This is carefully processed bone from tissue banks. It has been thoroughly sterilised and tested for safety. This type of graft has an excellent track record of success and integration.
• Autograft bone. This is bone that’s been taken from another part of your own body. It could be the chin, hip or another part of your jaw. This is considered the “gold standard” because it contains your own bone cells and growth factors.

The Procedure

During the grafting process, your dentist will:

1. Numb the treatment areas thoroughly with local anaesthetic.
2. Make a small incision in the gum to access the jawbone.
3. Carefully clean and prepare the bone surface.
4. Place the bone graft material in the required area.
5. Cover the graft with a protective membrane if necessary.
6. Stich the incision closed.

The process takes between 30 minutes to two hours depending on the size and complexity of the graft required.

Healing and Recovery

Healing can take several months – usually between three to six months.

During the initial healing phase, you may experience some mild swelling and discomfort. This can be managed with over-the-counter pain relief.

Your dentist will provide detailed aftercare instructions. This will include dietary recommendations, oral hygiene guidelines and signs to watch for during healing. Regular follow-up appointments mean your dentist will monitor the healing progress to make sure everything is going as expected.

Who Needs a Bone Graft?

Whether or not you need a bone graft depends on several factors:

Long-term missing teeth

When teeth are missing for months or years, the surrounding jawbone gradually shrinks due to lack of stimulation. The longer teeth have been missing, the more likely it is that bone grafting will be necessary. Even if you’ve worn dentures/” data-type=”treatment” data-id=”496″>dentures or partial dentures, bone loss can happen because these don’t provide the same stimulation to the jawbone as natural tooth roots do.

Advanced Gum Disease

Periodontal disease affects the bone supporting the teeth. Advanced gum disease can cause significant bone loss around the affected teeth. It often requires bone grafting to restore adequate bone volume. If you’ve lost teeth because of this, it’s likely bone grafting will be needed.

Jaw Trauma or Injury

If you’ve experienced trauma to the jaw from accidents, sports injuries or other causes, it could have caused bone loss or damage that requires grafting. Even if the injury occurred years ago, it may have affected the bone density and volume. Facial trauma can also cause irregular bone healing, creating areas that need to be rebuilt or reshaped before implant surgery.

Natural Bone Anatomy

Some people naturally have thinner jawbones or less dense bone tissue. Sometimes, certain areas of the mouth like the upper jaw at the back need grafting just because the bone is naturally thinner there.

A person’s individual bone anatomy is influence by genetics, age and overall health. It plays a significant role in determining whether grafting is necessary.

Will You Need Bone Grafting?

Before any implants are done, your dentist will use advanced imaging techniques. These will check the density and volume of your jawbone to see if their sufficient for implants. They will use:

• Digital X-rays. These provide a basic view of bone levels and density around the proposed implant site.
• 3D CT scans. These offer detailed, three-dimensional images. They should exact bone measurements, density and the relationship to important structures like nerves and sinuses.
• Clinical examination. The dentist will physically assess your gums, remaining teeth and jaw structure.
• Medical history. Understanding conditions or medications that could affect bone healing is essential.

Based on these assessments, your dentist can determine not only whether you need bone grafting but also what type of graft would be most appropriate for your situation.
