Dental implants are replacement tooth roots placed in the jawbone to support a crown, bridge or denture. They can replace one missing tooth, several teeth or a full arch, but the right treatment depends on your oral health, bone, bite and the restoration you need.

This page explains the main implant options, how a single implant differs from All-on-4 and what a personalised implant plan should cover before treatment begins.

What is a dental implant?

An implant is placed in the jawbone and used as a foundation for a replacement tooth or teeth. After assessment and planning, the final restoration may be a single crown, an implant-supported bridge or an implant-supported denture. Titanium is a commonly used implant material.

Not every missing tooth requires the same approach. The number and position of missing teeth, available bone, gum health and the desired final restoration all affect the plan.

Single-tooth implant vs All-on-4

Single-tooth implant

A single-tooth implant is planned to replace one missing tooth. It usually supports one custom crown through an abutment. This approach can be considered where a single gap needs to be restored without preparing the neighbouring teeth for a conventional bridge.

All-on-4

All-on-4 is a full-arch concept in which four implants support a complete set of replacement teeth for one jaw. It is not a four-tooth replacement and it is not the default option for someone missing a single tooth. See our dedicated All-on-4 dental implants page for the full-arch treatment pathway.

All-on-6 and other implant-supported options

All-on-6 uses six implants to support a full arch. Implant-supported bridges and dentures can also be considered when multiple teeth are missing. The choice between these options is made after the clinical assessment, not from a material or implant count alone. Read more about All-on-6 dental implants.

Can implants be placed on the same day?

“Same-day dental implants” can describe a treatment plan where a temporary tooth or temporary set of teeth is placed on the day of implant surgery. It does not mean every patient receives the same procedure or a final permanent restoration immediately.

The feasibility of an immediate plan depends on the examination, implant stability, bone and gum condition, bite and the planned restoration. Your dentist should explain what will be temporary, what happens during healing and when the final restoration is expected.

What happens during implant treatment?

  1. Assessment and imaging: The dental team checks teeth, gums, bone and the area to be restored. X-rays or scans may be used to plan placement.
  2. Personalised treatment plan: The plan sets out the number and position of implants, the planned crown, bridge or denture, and whether any preparatory care is needed.
  3. Implant placement: The implant is placed according to the plan. A temporary restoration may be used when appropriate.
  4. Healing and review: The team monitors healing and integration before the final restoration is completed.
  5. Final restoration and follow-up: A crown, bridge or denture is fitted, then checked for fit, bite and cleanability.

What can affect an implant plan?

  • the number and location of missing teeth
  • bone volume and the anatomy of the planned implant site
  • gum health, existing periodontal disease and the ability to keep the area clean
  • the bite, clenching or grinding forces, and the restoration planned above the implant
  • any additional care needed before implant placement

Where gum disease or other oral-health issues are present, these should be assessed as part of the plan. Our periodontal treatments page explains care for gum disease around natural teeth.

Long-term implant care

Implants do not decay, but the gum and bone around them still need care. Daily cleaning, professional reviews and early assessment of bleeding, swelling, recession or a changed bite help support long-term implant health.

If there are symptoms around an existing implant, see our information on peri-implantitis treatment. That page is about inflammation around implants and does not replace an individual examination.

Plan your dental implant treatment

A meaningful implant consultation should clarify the option being considered, the sequence of care, what is included in the proposed restoration and the expected follow-up. Review the clinic’s current price information, learn more about the treatment-plan process and meet the clinical team. You can request a personalised assessment through the contact page.
