All-on-4 Implants: Goodbye to artificial dentures in a day
All-on-4 implants offer patients who have worn removable dentures for years a permanent alternative — fixed teeth fitted on the same day as surgery, without the movement, discomfort and daily removal that makes conventional dentures so limiting. The transformation happens in a single clinic visit: patients arrive with failing or missing teeth and leave with a complete fixed prosthesis supported by four titanium implants.
The psychological impact of this change is significant. Many patients describe years of avoiding social situations, covering their mouth when laughing, or declining food they enjoy — all because their dentures were uncomfortable or unstable. All-on-4 implants eliminate these limitations immediately, restoring not just function but confidence.
At Asensio Advanced Dentistry in Valencia, we use Nobel Biocare and Klockner implants — the most clinically validated brands in implantology — and back every implant with a lifetime guarantee on materials. The treatment is performed under the direction of Dr. Lucía Asensio Romero, specialist in implantology and oral surgery with over 30 years of clinical experience. For a complete overview of the procedure and pricing, see our All-on-4 dental implants abroad page.
Why All-on-4 implants are better than artificial dentures
Artificial dentures have been the standard solution for full arch tooth loss for decades, but they have fundamental limitations that no amount of adhesive or adjustment can fully resolve. All-on-4 implants address each of these limitations directly, because they are anchored in the bone rather than resting on the gum.
| Problem with artificial dentures | How All-on-4 solves it |
|---|---|
| Movement during eating and speaking | Fixed permanently to four implants — does not move |
| Jaw bone loss accelerates without root stimulation | Implants stimulate the bone preventing further resorption |
| Must be removed daily for cleaning | Cleaned in place with standard brushing and interdental tools |
| Requires periodic relining or replacement | Implant material carries lifetime guarantee |
The transition from removable dentures to All-on-4 is one of the most impactful treatments in modern implantology — not because the technology is complicated, but because the result changes daily life immediately and permanently.
What happens on the day of All-on-4 surgery
The surgical session at Asensio typically takes between four and six hours depending on the complexity of the case. The entire process — extractions, implant placement and fitting of the provisional prosthesis — is completed in a single visit under local anaesthesia. Conscious sedation is available for patients who prefer it.
After the procedure, patients are given detailed aftercare instructions, prescribed pain relief and anti-inflammatory medication, and are able to return to their accommodation the same day. Most patients describe the experience as far less uncomfortable than they anticipated. Solid food should be avoided for the first few weeks while the implants begin to integrate, but normal soft food is possible from the first day.
The cost of All-on-4 at Asensio is £6,480 per arch, including all extractions, implants and the same-day provisional prosthesis. View the full breakdown on our prices page.

Frequently asked questions about All-on-4 implants
Can I really leave the clinic with fixed teeth the same day?
Yes. The fixed provisional prosthesis is attached to the implants on the same day as surgery. It is not a removable device — it stays in place while the implants integrate with the bone over the following months. At the second visit the provisional is replaced with the definitive restoration.
Is All-on-4 suitable for patients who have worn dentures for many years?
Yes, in most cases. Long-term denture wearers often have some degree of bone loss, but the angled All-on-4 technique is specifically designed to maximise available bone and avoid grafting in most cases. Every patient is assessed individually with a 3D CT scan. Severely atrophic cases may be treated with zygomatic implants as an alternative.
How long do All-on-4 implants last?
The titanium implants themselves are designed to last a lifetime and carry a lifetime guarantee on materials at Asensio. The prosthetic restoration — the visible teeth — may require maintenance or renewal over time depending on wear and the materials used. Regular professional reviews help identify and address any issues early.
What is the recovery like after All-on-4 surgery?
Most patients experience mild to moderate swelling and discomfort in the first few days, managed with standard pain relief. The majority return to light activity within two to three days. Strenuous exercise and hard food should be avoided for several weeks. A soft diet during the osseointegration period is recommended but normal eating is resumed fully once the definitive prosthesis is fitted.
How do I find out if I am a candidate for All-on-4?
The best way is a free consultation at Asensio, which includes a panoramic OPG X-ray and clinical assessment. Call us on 0800 048 8058, email office@dentalasensio.co.uk, or visit our All-on-4 page for full details.
