Nobel All-on-6
A full arch on six implants, where the bone supports the extra support
All-on-6 describes a full arch of fixed teeth carried on six implants rather than four. The extra pair spreads the chewing load across more anchorage points and shortens the unsupported spans in the bridge, which is why it is often preferred where the bone allows it and the bite is heavy. It is worth being precise about the naming: All-on-4 is a treatment concept defined by Nobel Biocare, whereas All-on-6 describes a six-implant approach that can be carried out with Nobel Biocare systems. Whether four or six implants suit your jaw is determined by CBCT assessment.
How the treatment runs
-
Assessment and planning
CBCT assessment establishes whether six implant positions with adequate bone exist.
-
Extractions where needed
Remaining unrestorable teeth in the arch are removed at the surgical visit.
-
Implant placement
Six implants are placed across the arch, spreading support more widely than a four-implant plan.
-
Provisional restoration
A fixed provisional may be fitted early where the stability measured at placement allows it.
-
Healing and final restoration
After integration, the definitive bridge is made and fitted.
Alternatives you should know about
- A four-implant full-arch plan where the bone and bite allow it
- An implant-retained overdenture
- A full removable denture
- Bone grafting followed by conventional implant placement
Six instead of four — what actually changes
Two things. The load from chewing is shared between more implants, so each one carries less. And the bridge sitting on top has shorter unsupported spans between its supports, which reduces the leverage acting on the end implants.
Neither of those is a small detail in a full arch. The forces involved are considerable, and they concentrate at the ends of a bridge. More support points closer together is mechanically the safer arrangement — when the bone is there to provide them.
When four is the better plan anyway
The extra two implants need somewhere to go, with enough bone around them to be worth having. In a jaw where the back has resorbed substantially, forcing in two more implants may mean placing them into poor bone or grafting first — and an implant in inadequate bone contributes less than the arrangement it complicates.
That is why a four-implant plan with angled rear implants exists. It is not the budget version; it is the arrangement that suits a jaw where the usable bone sits forward. Neither plan is a tier of service, and a clinic that presents them as such is selling rather than planning.
A note on the name
All-on-4 is Nobel Biocare’s defined treatment concept, with its own protocol and components. All-on-6 is the general description of a six-implant full arch — carried out here with Nobel Biocare implant systems. The distinction matters when comparing quotes, because two clinics using the same words may be describing different things.
Getting a specific answer
Send a recent CBCT scan, or a panoramic radiograph if that is what you have, with a note on your history and what you would like to achieve. The clinical team at Taki Dent can review it and set out whether four or six implants is appropriate, with a cost range. A final plan is confirmed after clinical examination and radiological assessment at the clinic.
