If you have lost most or all of your teeth in one or both arches, full-arch dental implants offer a permanent, fixed solution that looks and functions like natural teeth. Two of the most well-established approaches are All-on-4 and All-on-6 — both designed to replace an entire arch of teeth without the need for individual implants for every missing tooth.

Both All-on-4 and All-on-6 give you a full set of fixed, non-removable teeth anchored to implants — the key difference is how many implants support the prosthesis.

Choosing between the two depends on your bone density, jaw anatomy, clinical needs, and personal goals. This guide breaks down the differences so you can have a more informed conversation with your implant dentist about which approach is right for you.

Understanding the Options

All-on-4 Implants

The All-on-4 concept uses four implants per arch to support a full bridge of teeth. Two implants are placed vertically at the front of the jaw, while the two posterior implants are tilted at an angle — typically around 30 to 45 degrees.

  • Tilted posterior implants maximise contact with available bone
  • Often avoids the need for bone grafting
  • Immediate temporary teeth possible in many cases
  • Well-suited for patients with moderate bone loss

All-on-6 Implants

The All-on-6 concept uses six implants per arch, providing two additional points of anchorage compared to All-on-4. The extra implants are typically placed in the premolar region.

  • Six points of support for the prosthetic arch
  • May distribute bite force more evenly across the jaw
  • Immediate temporary teeth also possible (case-dependent)
  • Often recommended when there is adequate bone volume

The additional implants can provide extra stability, particularly for patients with larger jaw arches or those who want maximum long-term support.

Side-by-Side

All-on-4 vs All-on-6 Comparison

A clear overview of the key differences between the two full-arch implant approaches.

Feature All-on-4 All-on-6
Implants per arch 4 6
Bone grafting Often avoided (tilted implants) Sometimes needed
Immediate loading Yes (case-dependent) Yes (case-dependent)
Bite force distribution Distributed across 4 points Distributed across 6 points
Cost Lower (fewer implants) Higher (additional implants)
Medisave claimable Up to $5,000 Up to $7,500
Healing time 3 – 6 months (final prosthesis) 3 – 6 months (final prosthesis)
Suitability Moderate bone loss Adequate bone volume

Medisave figures are based on $1,950 per implant fixture. Bone grafts ($1,950 each) and sinus lifts ($1,950 each) are also individually claimable if required. For a detailed breakdown, see our dental implant cost guide.

Finding the Right Fit

Who Is Each Option For?

Your dentist will recommend the approach that matches your bone condition, jaw anatomy, and treatment goals.

All-on-4 May Be Right If You...

Have experienced moderate bone loss in the jaw and want to avoid additional grafting procedures. All-on-4 is also well-suited for patients seeking a cost-effective full-arch solution, as fewer implants are needed.

All-on-6 May Be Right If You...

Have adequate bone volume and want maximum stability with more points of anchorage. Patients with larger jaw arches may particularly benefit from the additional support that six implants provide.

Both Options Suit You If You...

Have lost most or all of your teeth in an arch. Are tired of removable dentures and want a fixed, permanent solution. Want teeth that look, feel, and function like natural teeth — anchored securely to implants.

Which option is right for you?

The decision between All-on-4 and All-on-6 is clinical — it depends on your bone density, jaw anatomy, bite pattern, and overall oral health. A 3D scan and consultation will give your dentist the information needed to recommend the approach that offers the most predictable long-term result for your specific case.

The Full-Arch Implant Procedure

Whether you choose All-on-4 or All-on-6, the general treatment journey follows a similar path. Here is a brief overview of what to expect.

1. Consultation and 3D Planning

Your dentist will conduct a thorough clinical examination and take a CBCT 3D scan to assess your bone volume, density, and jaw anatomy. This information is used to plan the precise placement of each implant.

2. Implant Placement Surgery

The implants are surgically placed into the jawbone under local anaesthesia. For All-on-4, the two posterior implants are angled to maximise bone contact. For All-on-6, the implants are distributed more evenly across the arch. The procedure typically takes two to four hours per arch.

3. Immediate Temporary Teeth

In many cases, a temporary fixed prosthesis can be attached to the implants on the same day as surgery. This means you can leave the clinic with functional teeth while the implants integrate with the bone.

4. Healing and Integration

Over three to six months, the implants fuse with the jawbone through a process called osseointegration. During this time, you will attend follow-up appointments to monitor healing.

5. Final Prosthesis

Once the implants have fully integrated, your permanent prosthesis is fabricated and fitted. This is custom-designed for a natural appearance and comfortable bite.

Cost Considerations

Both All-on-4 and All-on-6 are significant investments in your oral health, function, and quality of life. Pricing is customised based on the number of implants, the prosthetic material selected, and whether additional procedures such as bone grafts or sinus lifts are needed.

The good news is that each implant is individually Medisave claimable at up to $1,950 per implant fixture. This means:

  • All-on-4: Up to $5,000 in Medisave claims per arch (4 implants × $1,950)
  • All-on-6: Up to $7,500 in Medisave claims per arch (6 implants × $1,950)
  • Bone grafts are claimable at up to $1,950 each
  • Sinus lifts are claimable at up to $1,950 each

Because full-arch treatment involves multiple components, we recommend booking a consultation for a personalised treatment plan and transparent, itemised quote. Read our dental implant cost guide for more on pricing and Medisave.

Common Questions

Frequently Asked Questions

Everything patients ask about All-on-4 and All-on-6 dental implants.

All-on-4 uses four implants per arch to support a full set of fixed teeth, with the two posterior implants tilted to maximise bone contact. All-on-6 uses six implants per arch, providing additional points of support and potentially more even bite force distribution. Both replace an entire arch of missing teeth with a fixed, non-removable prosthesis.
Yes. Each implant in a full-arch treatment is individually Medisave claimable at up to $1,950 per implant fixture. For All-on-4 (4 implants), the maximum Medisave claim is up to $5,310 per arch. For All-on-6 (5 or more implants), up to $6,120 per arch. Bone grafts ($1,950 each) and sinus lifts ($1,950 each) are also separately claimable if required.
Pricing for full-arch implant treatment is customised based on the number of implants, prosthetic material, and whether additional procedures like bone grafts are needed. Each implant is individually Medisave claimable, which can significantly reduce out-of-pocket costs. Book a consultation for a personalised treatment plan and quote. See our cost guide for more details.
Neither is inherently better — the right choice depends on your individual clinical situation. All-on-6 provides more points of support and may distribute bite forces more evenly, which can be advantageous for patients with larger jaws or adequate bone volume. All-on-4 is often suitable for patients with moderate bone loss, as tilted posterior implants can avoid the need for bone grafting. Your dentist will recommend the approach that gives you the most predictable long-term outcome.
In many cases, yes. Both All-on-4 and All-on-6 protocols can support immediate loading, meaning a temporary fixed prosthesis is attached on the same day as surgery. This allows you to leave the clinic with functional teeth. A permanent prosthesis is typically fitted after the implants have fully integrated with the jawbone, usually three to six months later.
The surgical placement of implants typically takes two to four hours per arch, depending on complexity. If immediate loading is possible, you may receive a temporary prosthesis the same day. The full treatment timeline — from initial consultation to final permanent prosthesis — is generally three to six months, allowing time for the implants to integrate with the jawbone.
