All-on-X

Full-arch tooth replacement supported by four to six strategically placed implants

All-on-X (sometimes referred to as All-on-4 or All-on-6) is a full-arch implant-supported restoration that replaces all the teeth in an upper or lower arch using a fixed bridge anchored to four to six implants. The technique is designed to maximise the use of available bone — often placing some implants at an angle — to avoid the need for extensive bone grafting in many cases. The result is a fixed prosthesis that is not removed for daily cleaning. This treatment is considered a major surgical procedure and is not suitable for all patients. Candidacy depends on bone volume, overall health, and other individual factors that your treating specialist will assess.

What the Process Involves

  1. 1

    Specialist assessment and imaging — a thorough examination including CBCT scan is carried out to evaluate bone volume, nerve positions, and sinus anatomy to plan safe implant placement.

  2. 2

    Prosthetic planning — the shape, size, and appearance of the final bridge are planned in advance, often using digital design tools; your input on aesthetics is considered within clinical limitations.

  3. 3

    Surgical placement — all implants are placed in a single surgical session; in many cases a provisional (temporary) fixed bridge is attached on the same day, though this is not always possible.

  4. 4

    Healing and osseointegration — a period of 3–6 months is required for the implants to integrate with the bone; dietary restrictions apply during this phase to protect healing implants.

  5. 5

    Final bridge placement — once integration is confirmed, the definitive prosthesis is fabricated and fitted; adjustments may be made at follow-up appointments to refine fit and bite.

Recovery

All-on-X surgery typically involves a more significant recovery than single-implant placement. Swelling, bruising, and discomfort in the days following surgery are expected. A restricted diet (soft or liquid foods) is required for several weeks. Pain and function generally improve progressively over the first few weeks, though full recovery and final prosthesis placement may take six months or more.

Important Considerations

All-on-X is a major, irreversible commitment. It is not suitable for patients with active gum disease, uncontrolled diabetes, certain bone conditions, or who smoke heavily. Some patients may still require bone grafting prior to implant placement. The provisional bridge worn during healing is more fragile than the final prosthesis and must be treated with care. Long-term success requires diligent oral hygiene and regular professional maintenance. Costs are significant and vary depending on whether one or both arches are being treated, the type of final prosthesis, and case complexity.

Frequently Asked Questions

Can I eat normally with All-on-X implants?
After the full recovery period and with the final prosthesis in place, many patients find they can eat a broader range of foods compared to traditional dentures. However, very hard or sticky foods should generally be avoided to protect the prosthesis and underlying implants. Dietary guidance will be provided by your treating clinician.
What is the recovery time for All-on-X surgery?
The initial surgical recovery — swelling, bruising, discomfort — typically resolves over one to two weeks, though this varies between individuals. Dietary restrictions (soft foods) may apply for several weeks. The osseointegration period, during which the implants fuse with the bone, typically takes 3–6 months before the final bridge is placed.
Is All-on-X suitable if I currently have dentures?
Many patients seeking All-on-X are existing denture wearers looking for a more stable, fixed solution. Existing denture wearers may have experienced bone loss over time, which can affect candidacy. A detailed assessment is needed to determine whether sufficient bone exists or whether grafting is required before implant placement.
