All-on-4 and all-on-6: the convenient route to multiple dental implants

Living with multiple missing or failing teeth can be exhausting. Eating becomes harder. Smiling feels uncomfortable. Dentures can slip at the wrong moment. And the idea of replacing every tooth individually with separate implants might feel overwhelming.

Traditional one-by-one implants aren’t the only option.

All-on-4 dental implants and all-on-6 dental implants are an efficient way to restore a full set of teeth. What this means is that there isn’t an implant for every missing tooth. Instead, there are four or six implants. These are positioned in a way that will support an entire fixed bridge – either top or bottom.

What are all-on-4 and all-on-6 dental implants?

These are full-arch implant systems. That means they are designed to replace an entire upper or lower set of teeth.

Rather than placing eight, ten or even more individual implants, we place either four or six implants strategically into the jaw. These implants act as anchors. A custom-made full bridge of teeth is then secured on top.

In simple terms:

• Four or six implants are placed into the jawbone.
• They support a complete fixed prosthetic arch.
• The bridge replaces all teeth in the upper or lower jaw.

One of the biggest advantages is the “teeth in a day” concept. In suitable cases, a temporary fixed bridge can be fitted shortly after surgery. This means you don’t leave the practice without teeth while healing takes place.

After the implants have integrated with the bone, the temporary bridge is replaced. This final bridge is a stronger, highly aesthetic restoration.

The result: a secure, fixed set of teeth that does not come out like a denture.

All-on-4 vs All-on-6: what’s the difference?

Both follow the same principle. The difference lies in the number of implants used to support the bridge.

Stability & Load Distribution

All-on-6 dental implants use two additional implants compared to All-on-4. This can offer enhanced load distribution across the jaw.

In patients with good bone density, this added support may provide increased long-term stability. It can be particularly beneficial for those with stronger bite forces.

All-on-4 dental implants are carefully angled to maximise existing bone and still provide excellent support. For many patients, four implants are more than sufficient.

Bone Grafting Requirements

One reason All-on-4 dental implants are so popular is that they are often designed to avoid bone grafting in suitable cases. By angling the back implants, we can make better use of available bone.

All-on-6 dental implants may require more bone volume, depending on placement. Every case is assessed individually using detailed imaging.

Cost Considerations

More implants typically mean a higher overall investment. All-on-6 dental implants generally cost more than All-on-4. This is because of the additional implants and components involved.

However, it’s important to think long-term. Both options are designed as permanent and full-arch. When deciding what’s best, you should think about durability, function and quality of life rather than just the cost.

We will explain the differences clearly during your consultations. We’ll give you a recommendation based on what suits your bone levels, bite and goals.

Benefits of full-arch implant solutions

Full-arch systems like All-on-4 dental implants and All-on-6 dental implants have significant advantages over traditional dentures.

Many people tell us they notice improvements immediately.

Key benefits include:

• Fixed, non-removable teeth.
• Improved chewing ability and food choices.
• A natural-looking smile.
• No slipping or messy adhesives.
• Support for the jawbone, helping reduce further bone loss.
• A long-term solution. They’re designed to last many years.

Implants stimulate the jawbone in the same way a natural tooth root does. This means they help maintain facial structure. Dentures, by contrast, sit on top of the gums. Over time, without tooth root (or implant) stimulation, bone shrinkage can happen.

There’s also a psychological benefit. Knowing your teeth are secure changes how you speak, laugh and eat in social settings.

Who is suitable for All-on-4 or All-on-6?

These treatments are suitable for:

• Patients with multiple missing teeth.
• Those with several failing teeth that require extraction.
• Denture wearers who want a fixed alternative.
• Patients with some degree of bone loss (subject to assessment).

A detailed consultation will determine your suitability. We carry out a full clinical examination. This includes taking CBCT scans to assess bone levels and anatomical structures. We’ll then be able to plan implant placement precisely.

Not everyone will be suitable immediately. In some cases, preparatory treatment is needed. Examples include extractions or addressing gum health beforehand.

There is no one-size-fits-all approach as nobody’s mouth and needs are identical.

Final thoughts

All-on-4 dental implants and all-on-6 dental implants are a stable way to replace a full arch of teeth. It means there’s no need for multiple individual implants.

If you’re frustrated with loose dentures or facing the loss of several teeth, this could be the solution. And one that restores both confidence and function.

The next step is a consultation. Our team will assess your mouth, explain your clearly and help you decide what’s best for you.
