All-on-4 dental implants abroad is a full-arch rehabilitation technique that replaces all the teeth in one jaw using just four strategically placed implants — with fixed provisional teeth fitted on the same day as surgery. For patients from the UK who have lost most or all of their teeth, All-on-4 in Spain offers the same Nobel Biocare implants used in British clinics at 55% to 70% lower cost, with a lifetime guarantee on materials.
Living with unstable dentures that move when you speak or eat significantly affects quality of life. Many patients are told they need extensive bone grafting before they can have fixed teeth again — adding cost, recovery time and complexity. All-on-4 is specifically designed to work with the available bone by angling the posterior implants, which means most patients can have fixed teeth without grafting, in a single trip to Valencia.
At Asensio Advanced Dentistry the All-on-4 procedure is planned and performed by Dr. Lucía Asensio Romero, a specialist in implantology and oral surgery with over 30 years of experience and more than 5,000 implants placed. We use 3D digital planning and guided surgery to achieve precise implant positioning and predictable results.
What is All-on-4 and how does it work?
All-on-4 uses four implants per arch — two placed vertically at the front and two angled at 45 degrees at the back. The angled posterior implants maximise contact with available bone and avoid anatomical structures such as the maxillary sinus or the mandibular nerve. This design provides immediate stability strong enough to support a fixed provisional prosthesis on the same day.
Unlike conventional full-arch rehabilitation that may require 6, 8 or more implants and often bone grafting, All-on-4 achieves excellent results with fewer implants in less time. After a healing period of 3 to 6 months, the provisional prosthesis is replaced with the definitive restoration.
All-on-4 abroad vs All-on-6: which is right for you?
| Treatment |
Indicated for |
Main advantage |
| All-on-4 |
Full arch loss, limited bone |
Less invasive, most cost-efficient, avoids grafting |
| All-on-6 |
Full arch loss, good bone volume |
More implant support where anatomy allows |
The right choice depends on your bone volume, bite force requirements and overall clinical situation. Both options are assessed during the free first consultation using a 3D CT scan. View our full dental implants abroad page for an overview of all implant options.

Most All-on-4 cases require two trips to Valencia. The consultation and surgery can be scheduled on consecutive days, and the osseointegration period is spent at home in the UK with fully functional provisional teeth. Find out more about how our dental tourism process works.
Why choose Asensio for All-on-4 abroad?
We use exclusively Nobel Biocare and Klockner implants — the two most clinically validated implant brands in the world — and back every case with a lifetime guarantee on materials. Our ISO 9001 certification from AENOR means our clinical processes are independently audited to the same standards as major European hospital groups.
We also accept complex cases that other clinics have rejected, including patients with significant bone loss. In cases of severe maxillary atrophy where standard All-on-4 is not viable, we offer zygomatic implants as an alternative. Call us free on 0800 048 8058 or email office@dentalasensio.co.uk to discuss your case.
Once your All-on-4 is in place, proper daily cleaning is essential to protect your investment long term. See our dental implant care guide and our dedicated All-on-4 cleaning guide for everything you need to know.
Frequently asked questions about All-on-4 abroad
How much does All-on-4 cost abroad in Spain?
A single arch All-on-4 at Asensio costs £6,480 including all extractions, four Nobel Biocare or Klockner implants and fixed provisional teeth on the same day. Both arches cost £12,960. View the full breakdown on our prices page.
Can I get All-on-4 if I have little bone?
In most cases yes. The angled posterior implants are specifically designed to maximise available bone and avoid grafting. For severe bone atrophy we assess whether All-on-4 is viable or whether zygomatic implants are more appropriate. Every case is evaluated with a 3D CT scan.
How many trips to Spain does All-on-4 require?
Typically two trips. The first covers the consultation and surgery — these can be scheduled on consecutive days. You return home with fixed provisional teeth and come back 3 to 6 months later for the definitive restoration.
Is All-on-4 painful?
The surgery is performed under local anaesthesia. Conscious sedation with nitrous oxide is available for patients who prefer it. Most patients report manageable postoperative discomfort rather than severe pain, and return to normal activity within a few days.
How long does All-on-4 last?
With proper maintenance and regular professional reviews the implants can last for many years. The prosthesis may require maintenance or renewal over time depending on materials and wear. All implant materials carry a lifetime guarantee at Asensio.
