All-on-6 describes a complete fixed arch supported by six dental implants. It is not automatically superior to All-on-4. The appropriate number and position of implants depends on anatomy, bone, the planned bridge, hygiene access, bite and how complications would be managed.

What is All-on-6?
Six implants are distributed across an upper or lower arch to support a fixed bridge. The extra implant positions may provide a different support pattern, but they also require suitable bone and restorative planning.
As with any full-arch treatment, the bridge replaces teeth and often some missing gum volume. Implant placement needs to be prosthetically driven rather than based only on where bone appears available.

All-on-6 versus All-on-4
The difference is not simply six versus four. Each concept can use different implant positions, bridge spans and restorative designs. Four well-positioned implants may be more appropriate than six poorly distributed ones; in another patient, six implants may suit the plan better.
Ask why the recommended number fits your anatomy, whether any implant is intended as reserve support and how the bridge would be managed if one implant developed a problem.
- Available bone and anatomical structures
- Number and position of implants
- Length and design of the bridge
- Bite forces and history of grinding
- Ease of cleaning beneath the restoration

Treatment stages
Assessment normally includes medical history, gum and tooth examination, bite records and 3D imaging. Teeth may be removed and implants placed during the first surgical phase. A fixed temporary bridge may be possible when initial stability and risk factors permit.
After healing, new records and try-ins guide the final bridge. The team checks appearance, speech, comfort, bite and hygiene access before completion.

Maintenance and limitations
Six implants do not remove the risk of peri-implant disease, component loosening or bridge wear. Daily cleaning beneath the bridge and professional maintenance remain essential.
If cleaning space is too narrow or the design is bulky, additional implants can make hygiene more complex. The final design should balance support with maintainability.
