What is Full-Arch Solutions (All-on-4 / All-on-6)?

Full-arch treatment uses implants to support replacement teeth across an upper or lower arch. All-on-4 and All-on-6 describe approaches using four or six implants. These approaches may be considered when an entire arch requires replacement teeth. Bone, bite, medical history and the remaining teeth need individual assessment.

Who it may be for

These approaches may be considered when an entire arch requires replacement teeth. Bone, bite, medical history and the remaining teeth need individual assessment. A consultation decides.

How suitability is assessed

An arch means the full row of upper or lower teeth. The examination considers which teeth can be retained, bone support, gum disease, bite forces and your ability to clean beneath a proposed fixed restoration. Records support the examination rather than replace it.

What happens at the clinic

  1. Review the whole arch

    The clinic assesses the remaining teeth, supporting structures and bite.

  2. Compare the plan

    The plan identifies teeth to retain or remove, implant positions and the type of replacement teeth. Placement, healing and any temporary restoration are discussed separately; a temporary fixed restoration is not suitable in every case.

  3. Restore and maintain

    After the support and tissues are ready, the planned replacement teeth are fitted and the bite checked. Cleaning access and maintenance are reviewed before and after completion.

Options and limitations

An implant-supported removable overdenture may be an alternative to fixed replacement teeth. The number of implants is a clinical decision. Surgery, healing, cleaning access and the possibility of repair or implant failure must be discussed; temporary teeth and final teeth are different stages, when a temporary restoration is suitable.

Care and follow-up

Ask for a demonstration of cleaning beneath the replacement teeth and around the implant supports. Follow the food and activity instructions for each stage, including any temporary teeth. Reviews check the bite, implants and restoration; components may require maintenance or replacement.

Questions you may have

How is All-on-4 different from All-on-6?

The names describe the number of implants used in these approaches. The appropriate arrangement depends on assessment rather than a preference for a particular number.

Is this the same as a removable denture?

A fixed full-arch restoration and an implant-supported removable overdenture are different options. The clinic can explain which arrangements may be suitable.

Will I receive the final teeth immediately?

The stages and type of restoration depend on clinical findings. Ask for a personal treatment plan rather than assuming an immediate final restoration.

Can healthy remaining teeth be kept?

Ask which teeth are suitable to retain and why removal is being proposed. Full-arch treatment is not a reason on its own to remove every remaining tooth; examination and the wider plan guide that decision.
