All-on-6 vs All-on-4 Dental Implants

If you need to replace a full row of teeth, you may hear about both All-on-4 and All-on-6 dental implants. The idea is similar in both treatments: several implants are placed in the jaw to support a fixed set of replacement teeth. The main difference is the number of implants used.

What is the difference between All-on-4 and All-on-6?

All-on-4 uses four implants to support a full arch of teeth, while All-on-6 uses six. Both can be used for the upper jaw, lower jaw, or both. The extra two implants in an All-on-6 case can provide additional support, but that does not automatically make it the better option for everyone.

Why would a dentist recommend All-on-6?

A dentist may recommend All-on-6 if you have enough healthy bone to support six implants and if the extra support would be helpful for your bite or treatment plan. Spreading the pressure across more implants can sometimes improve stability, especially for patients who have strong chewing forces or a larger arch.

Why would someone choose All-on-4 instead?

All-on-4 can work well for people who have limited bone in certain areas or who want to avoid more extensive procedures. The back implants are often placed at an angle to make better use of available bone. In some cases, this can reduce the need for bone grafting and make treatment possible with fewer implants.

Does All-on-6 last longer than All-on-4?

Not necessarily. Both treatments can last many years when the implants are placed properly and cared for well. Long-term success depends on things like bone quality, oral hygiene, smoking, bite pressure, overall health, and regular dental care. Using more implants does not guarantee a longer-lasting result.

Is one option more comfortable?

Once healing is complete, both treatments are designed to feel stable and secure. You may notice differences during recovery because All-on-6 involves placing two additional implants, but comfort varies from person to person. The fit and design of the final teeth usually have a bigger effect on everyday comfort than the number of implants alone.

Does All-on-6 cost more?

Usually, yes. Because All-on-6 uses more implants, it often costs more than All-on-4. The total price also depends on whether you need extractions, bone grafting, sedation, temporary teeth, or other procedures. The materials used for your final teeth can make a difference in the cost too.

Which option is better for bone loss?

All-on-4 is often considered when a patient has some bone loss because the implants can sometimes be placed in areas where stronger bone is still available. All-on-6 generally requires enough bone to support the additional implants. Your dentist will need imaging to see what your jawbone can support safely.

Which one is right for me?

That depends on your bone, bite, remaining teeth, and overall treatment goals. Some patients do very well with four implants, while others benefit from six.
