All-on-4 in Valencia is an advanced full-arch rehabilitation technique that allows us to replace all the teeth in one jaw with just four dental implants and a fixed provisional prosthesis on the same day of surgery. It is one of the most efficient solutions for patients with severe tooth loss, unstable dentures or advanced periodontal deterioration.
Many patients live for years with removable dentures that move when they speak, rub when they chew and gradually reduce their quality of life. Others are told they need many implants or extensive bone grafting before they can have fixed teeth again. In many of these cases, All-on-4 is the treatment that changes everything: fewer implants, less surgery and immediate function.
At Asensio Dental Clinic, treatment is planned and carried out by the team led by Dr. Lucía Asensio Romero, with digital 3D planning, guided surgery and fixed provisional teeth delivered the same day whenever the case allows it.
What is All-on-4 and how does it work?
All-on-4 is a full-arch implant protocol in which four strategically placed implants support a fixed prosthesis. The posterior implants are angled to maximise the available bone and avoid anatomical structures such as the maxillary sinus or the mandibular nerve. This design often makes extensive grafting unnecessary and speeds up rehabilitation.
Unlike conventional full-mouth implant treatments that may require 6, 8 or more implants per jaw, All-on-4 is designed to achieve excellent stability with a reduced number of implants, provided the diagnosis and surgical execution are precise.
Who is a candidate for All-on-4?
For severe maxillary atrophy, other techniques such as zygomatic implants in Valencia may be more appropriate. That is why the diagnosis matters more than the technique name.
All-on-4 vs All-on-6
| Treatment | Typical indication | Main advantage |
|---|---|---|
| All-on-4 | Full-arch restoration with limited bone | Less invasive and more cost-efficient |
| All-on-6 | Full-arch restoration with good bone volume | More implant support when anatomy allows |
All-on-4 treatment process step by step
1. Diagnosis and digital planning
We perform a full clinical examination, digital radiology and 3D scan to study bone volume, occlusion and prosthetic design. This stage determines whether All-on-4 is the best option or whether the patient is better suited to implants without bone grafting solutions.
2. Implant surgery
The four implants are placed under local anaesthesia, with conscious sedation available when needed. If remaining teeth are hopeless, extractions can be carried out in the same surgery.
3. Fixed provisional teeth on the same day
In suitable cases, the patient leaves the clinic with a fixed provisional prosthesis the same day. This is one of the greatest advantages of immediate-load implant treatment.
4. Final prosthesis
After the healing and osseointegration phase, the provisional prosthesis is replaced with the final restoration, designed for long-term function, aesthetics and hygiene.

Frequently asked questions about All-on-4
How much does All-on-4 cost in Valencia?
The cost depends on the prosthetic design, the arch treated and the complexity of the case. You can review general guidance on our dental implant prices page, but the exact quote is always personalised after diagnosis.
Is All-on-4 painful?
The surgery is carried out with local anaesthesia and can be combined with conscious sedation. Most patients report manageable postoperative discomfort rather than severe pain.
Can All-on-4 be done with little bone?
Often yes. The technique is specifically designed to take advantage of the available bone. In severe atrophy, however, other options such as zygomatic implants may be necessary.
How long does All-on-4 last?
With good maintenance, professional reviews and proper hygiene, the implants can last for many years. The prosthesis may require maintenance or renewal over time depending on materials and wear.
