All Missing Teeth Replacement

Understanding All-on-Four

  • Fixed full-arch bridge on implants (non-removable)
  • Computer-guided placement for strength & longevity
  • Immediate provisional teeth often possible same day

Known as Teeth in a Day and Same-Day Teeth, this procedure allows patients to visit our London implant clinic in the morning and leave in the afternoon with a fresh, complete set of new teeth.

All-on-4 typically places 4-6 dental implants, strategically angled to restore a full arch of up to 14 teeth, making it the ideal treatment for patients with bone loss and a full mouth of failing or missing teeth.

Patients can expect restored:

  • Strength – stable bite, no slipping and the least degree of movement
  • Aesthetics – natural smile design that feels like yours
  • Function – freedom to chew comfortably and speak without limits

Will All-on-4 work for you?

All-on-4 dental implants is designed for patients who:
  • Have all or most teeth missing (edentulous cases)
  • Have teeth that are failing, severely worn, or loose
  • Wear dentures but want a fixed, non-removable solution
  • Have terminal dentition, where remaining teeth must be removed

When many or all teeth are missing or beyond saving, a fixed full-arch bridge, such as All-on-4, can replace them with a natural-looking, permanent solution. It is an excellent option when other treatments are no longer predictable, and when patients want the closest thing to natural teeth.

Because the treatment uses angled implants, it can often avoid the need for prior bone grafting, which means that if you've been told "no", you're not suitable for traditional implants, All-on-4 might be the treatment you need to restore your smile.

To understand if you're a good candidate, book a consultation with our implant dentists in London today for £120, which includes your check-up and CBCT scan.

The All-on-4 procedure

At Angel Smile, every case is planned using 3D CBCT scans and virtual guided surgery. This ensures the implants are placed in the strongest bone, at the best angulations, for long-term stability and easier cleaning.

Step-by-step treatment breakdown - what to expect at each stage

Not only will your new arch of teeth look like the real thing, but they'll function and perform just like natural teeth, allowing for improved comfort, chewing and bite functions immediately after placement. 

Temporary teeth are immediately loaded to your implants the same day as placement, with your final restoration being placed around 3 months later, after a period of healing.

Consultation & Scan

3D CBCT, full assessment, discussion of your goals, oral health check and quotation with finance options explained. Consultations are held at our London clinic in Islington.

Virtual Planning

Design implant positions digitally for safety and precision and design your new prosthetic to match your goals and face.

Extractions (if required)

Remove failing teeth in a minimally invasive way before implants are placed.

Implant Placement

Place 4–6 implants in optimal positions. It can typically take around one hour per implant.

Immediate Provisional Bridge

Often possible the same day, giving you fixed teeth straight after surgery (when clinically suitable).

Final Full-Arch Bridge

After healing (around 3 months), your permanent bridge is fitted, custom-designed for strength, comfort, and aesthetics.
Fixing implant retained dentures

The Immediate provisional bridge is provided mostly for cosmetic reasons and is not functional for chewing. Until the implants integrate, it must be treated as non-functional. (Soft/liquid diet for 2–6 months until the final bridge fit).

Immediately-loaded implants & provisional false teeth

For suitable patients, it is possible to have implants placed on the same day as extractions and leave with a fixed provisional bridge. This means you never go without teeth during the healing period.

  • Immediate placement: Implants are inserted directly after tooth removal.
  • Immediate provisional: A temporary fixed bridge attached the same day, used while your implants heal.
  • Final bridge: After integration, a long-lasting full-arch bridge is made for maximum function and aesthetics.
It is important to understand:
The process where bone grows and fuses around them. This usually takes around 3 months, depending on bone quality and whether grafting was required.

All-on-4 (fixed) vs implant dentures (removable)

Patients often compare alternative full-mouth dental implant systems, such as implant-retained dentures (2–4 implants supporting a removable denture) and All-on-4 (4–6 implants supporting a fixed bridge).

Benefits Implant dentures All-on-4
Stability Secure but removable Fully fixed, non-removable

Speaking Clearer than denture Most natural, stable speech
Cost (from) £5,800 (2 implants) £15,600 (4 implants, temporary teeth + final set)

FAQs

Guide to All-on-Four Dental Implant Treatment

All-on-4 is a full-arch implant solution that replaces all teeth using just four implants to support a fixed bridge.

Yes, temporary fixed teeth are usually fitted on the same day as implant placement.

It’s ideal for patients with multiple missing or failing teeth, or those currently wearing dentures.

During the All-on-4 procedure, patients are given local anaesthesia to ensure comfort. Sedation can be arranged for additional relaxation, but it must be planned in advance and incurs extra costs. After surgery, mild soreness or swelling is normal and usually well controlled with prescribed medication.

Dental implants have a very high success rate, typically over 95% over 10 years when performed with proper planning, good bone support, and adequate aftercare.

Costs vary depending on individual needs. As a guide, a fixed, full-arch, implant-supported bridge costs around £15,600, including implants, components, surgeries, review visits during treatment, and both transitional and final bridges. A detailed treatment plan and quotation will be provided to you after your consultation and CT scan.

With proper home care, regular hygienist visits, and implant reviews by an implant-trained dentist, implants can last for decades in healthy individuals. The bridge needs maintenance and will require replacement over time, similar to how car tyres wear depending on the amount and type of use.

After the healing phase, your final bridge can be custom-designed based on your case, budget, and aesthetic preferences. Options typically include an Acrylic bridge with a metal or titanium framework or a Zirconia bridge. 

  • Permanent and can only be removed by a dentist
  • No need to remove teeth at meals or bedtime
  • Clean your them just like natural teeth
  • Palateless denture design (roof of mouth uncovered)
  • Restored bite and chewing function
  • Enjoy a varied diet again without limits

  • Dental implants that last up to 30 years
