Understanding the All-on-6 Approach
All-on-6 follows the same core principle as All-on-4 but uses six implants to support a full arch of fixed replacement teeth instead of four. The additional two implants distribute chewing forces more evenly across the jaw, which can be particularly advantageous for patients with strong bite forces or a longer dental arch.
This approach is often recommended when a patient has sufficient bone available to support extra implants, or when the treating surgeon wants an additional safety margin for long-term load-bearing, especially in the lower jaw where biting forces tend to be greater.
All-on-4 vs All-on-6
The choice between four and six implants depends on individual factors including bone density, arch length, bite strength, and whether any implants may need to be removed and replaced in future without disturbing the entire prosthesis. Six implants can offer more flexibility if one implant were ever to need attention.
Neither option is universally superior; both are proven long-term solutions and the decision is made after detailed CBCT imaging and a discussion of your specific oral health, lifestyle, and budget considerations with your implantologist.
Surgical Considerations
Placing six implants typically requires slightly more available bone, and in cases of moderate bone loss a small grafting procedure may be recommended in specific areas to ensure predictable long-term stability, particularly at the sites with the least bone volume.
The surgery itself follows a similar protocol to All-on-4, performed under local anaesthesia with sedation options available for anxious patients, and a temporary fixed bridge is generally provided on the day of surgery so you do not leave without teeth.
Long-Term Outcomes
Because the load is shared across more implants, All-on-6 restorations can offer a wider margin for biomechanical stress, which some clinicians consider beneficial for patients who grind their teeth or have a history of heavier bite forces.
Long-term success still depends heavily on daily hygiene and regular professional maintenance visits. Both All-on-4 and All-on-6 patients need to commit to lifelong care of the prosthesis and the gum tissue surrounding each implant to avoid complications such as peri-implantitis.
Questions patients ask us
- Why would a dentist choose six implants over four?
- Six implants can offer greater load distribution and a built-in safety margin, which may be preferred for patients with strong bite forces, longer arches, or where a dentist wants flexibility to manage one implant individually without affecting the entire prosthesis.
- Does All-on-6 need more bone than All-on-4?
- Generally, yes. All-on-6 typically requires a bit more available bone volume to accommodate the additional implants comfortably. Where bone is limited, your surgeon may recommend All-on-4 instead, or a localised grafting procedure to prepare the site.
- Is recovery different between the two techniques?
- Recovery timelines are broadly similar for both approaches, generally involving a few days of mild swelling or discomfort followed by weeks of internal healing while the implants integrate with the bone before the final bridge is fitted.
- Can I switch from All-on-4 to All-on-6 later?
- In some cases additional implants can be added later if bone and gum conditions allow, but this depends heavily on the individual case. It is best discussed with your implantologist during your initial CBCT-based treatment planning.
