All-on-4® and full-arch implants

Full mouth dental implants in Crewe

If most or all of the teeth in an upper or lower jaw are missing or cannot be predictably restored, a fixed full-arch bridge may be supported by a carefully planned number of implants, often four to six. We provide the All-on-4® treatment concept from Nobel Biocare.

Full-arch treatment starts from £15,995 per arch. Your confirmed fee depends on the clinical findings, planned number of implants, type of restoration and whether additional procedures are required. Following your assessment, your implant dentist will explain the recommended approach and provide a written treatment plan with the expected cost.

What it involves

All-on-4® and All-on-6

A fixed full-arch bridge is supported by a carefully planned number of implants, often four or six. The number and position are selected during clinical planning to suit your jaw, bite and proposed restoration.

  • Four implants

    All-on-4®

    The All-on-4® treatment concept uses four implants to support a full arch. Typically, two implants are positioned towards the front and two implants towards the back are placed at an angle. Their precise position depends on your anatomy and clinical planning.

  • Six implants

    All-on-6

    Six implants support the arch instead of four. Whether four or six implants are recommended depends on your jaw anatomy, available bone, bite and the planned bridge. Your implant dentist will explain the proposed number and positioning after your assessment and imaging.

Some patients can receive a temporary fixed bridge on the day their implants are placed, when the treatment plan and implant stability support immediate loading. In other cases, your implant dentist will plan a suitable temporary arrangement during healing. Your final bridge will be fitted at the appropriate stage in your individual treatment plan.

Weighing it up

How full-arch implants compare with dentures

Conventional dentures, implant-retained dentures and fixed full-arch bridges can all replace the teeth in an upper or lower jaw. They differ in whether they are fixed or removable, the treatment involved, maintenance requirements and cost.

  • Removable option

    Conventional denture

    Rests on the gums and is taken out for cleaning. Usually the least expensive of these three options and does not require implant surgery, although tooth extraction may sometimes be necessary before a denture is fitted.

    About dentures
  • Added denture stability

    Implant-retained denture

    Still removable, but held more securely using implants and special attachments. It may be considered by patients who want improved denture retention without choosing a fixed full-arch bridge.

    About implants
  • Fixed in place

    Full-arch fixed bridge

    Supported by a carefully planned number of implants, the bridge remains fixed in place for everyday use rather than being removed by you. Daily cleaning around the bridge and regular professional maintenance help protect both the implants and the restoration.

    from £15,995per arch, starting fee

The appropriate option depends on the clinical findings, your treatment goals, whether you prefer a fixed or removable restoration, cleaning and maintenance requirements, relevant risks and cost. Your implant dentist will explain the suitable alternatives and provide a written treatment plan before you decide whether to proceed.

The process

The All-on-4® and full mouth dental implant process

Treatment begins with a no-obligation consultation. The complete process often takes several months, with your individual timeline depending on the treatment plan, healing and any additional procedures.

  1. A conversation first
    Your implant dentist will ask about your concerns, previous dental experiences and what you would like treatment to achieve. This helps shape the assessment and the options discussed with you.
  2. Assessment and imaging
    Your dentist examines your mouth and reviews your dental and medical history. Digital X-rays and a CBCT scan may be recommended where clinically appropriate to assess the available bone and plan the implant positions.
  3. Understanding your options
    Your implant dentist explains the approaches that may be appropriate based on your assessment, including fixed full-arch implants and relevant removable alternatives. You will have time to ask questions and understand why a particular approach is recommended.
  4. A written treatment plan
    You receive a personalised written plan setting out the recommended treatment, the cost and the expected timeline. You are encouraged to take it away and think about it.
  5. Treatment and healing
    The implants are placed in their planned positions and allowed to integrate with the jawbone. Selected patients may receive temporary fixed teeth on the day of surgery, while the final bridge is fitted at the appropriate stage after healing. Sedation is available where clinically appropriate.

Your assessment

Planning All-on-4® and full mouth implant treatment

Your assessment gives the implant dentist the clinical information needed to plan All-on-4® or another full-arch implant approach and prepare an individual cost estimate. It considers your oral health, available bone, treatment goals and the restoration being planned.

What your dentist assesses

  • The quality and volume of bone in your jaw
  • The condition of your gums
  • Your general medical health
  • Smoking and other lifestyle factors that can affect healing
  • How your restoration will be cleaned and professionally maintained

What affects the cost

  • How many implants your case needs
  • Whether additional procedures such as grafting are required
  • The materials used for the bridge
  • The complexity of the case, and whether sedation is used

Where clinically indicated, additional procedures can help prepare the area for implant treatment. Current starting fees include bone grafting from £900, an internal sinus lift from £1,400 and an external sinus lift from £2,000. Sedation, where appropriate, starts from £950. Any additional treatment and its cost will be included in your written estimate before you decide whether to proceed.

Common questions

Full mouth dental implant questions

Answers to common questions about All-on-4®, full mouth dental implants, treatment times, temporary teeth and costs.

How are All-on-4® and full mouth dental implants planned?

Your implant dentist assesses your jawbone, gums, bite, medical history and daily cleaning needs, supported by appropriate diagnostic imaging. The findings are used to plan the number and position of implants and the type of full-arch bridge recommended for you.

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

The principal difference is the number of implants supporting the arch. Whether four or six implants are recommended depends on your jaw anatomy, available bone, bite and the planned bridge. Your implant dentist will explain the proposed number and positioning after completing the necessary assessment and imaging.

How long does full mouth dental implant treatment take?

Treatment often takes around three to six months, although the timeline varies with healing and any additional procedures included in your plan. Your expected stages and approximate timeline will be explained before treatment begins.

How long do full mouth dental implants last?

Full-arch implants are designed as a long-term tooth-replacement option. Their longevity depends on gum health, effective daily cleaning, smoking, general health and regular professional maintenance. The bridge and its components may require maintenance, repair or replacement at a different stage from the implants themselves.

Will I be left without teeth during treatment?

Your temporary teeth will be discussed and planned before treatment. Selected patients can receive a temporary fixed bridge on the day of implant placement. In other cases, your implant dentist will explain the appropriate temporary arrangement to use during healing.

How much do full mouth dental implants cost?

Full-arch implant treatment starts from £15,995 per arch. Your written treatment plan will confirm the cost for your individual treatment and whether treatment is planned for one or both arches. Treatment costing £350 or more may be eligible for finance arranged with Chrysalis Finance, subject to status and affordability. See our finance options page for more information.
