Do you find it hard to eat your favorite foods or to eat healthily because you have lost all your teeth? The All-on-4 technique is a solution that restores chewing function for a whole arch and gives you back a stable, natural-looking smile. In this detailed article you will find out all about the procedure: from the basic steps to the benefits, stages and practical tips. Whether you are simply curious or ready to take action, here you will find the information you need to make an informed decision.
What is the All-on-4 technique?
All-on-4 is a dental implantology method developed to replace all the teeth in one arch, either the lower jaw (mandible) or the upper jaw (maxilla). In the lower jaw, where the bone is denser, four implants are enough: two at the front placed vertically and two at the back tilted at an angle of up to 45 degrees, making the most of the available bone and often avoiding the need for bone grafts. In the upper jaw, where the bone is softer, All-on-4 can work with four implants in favorable cases, but more implants are usually needed, the exact number depending on each patient’s individual situation. Unlike traditional removable dentures, which can slip or cause discomfort, this technique provides a fixed prosthesis firmly anchored in the bone.
This method, introduced by Nobel Biocare, is well suited to people with moderate bone loss, offering a more accessible and quicker alternative to traditional implant treatment that would require more appointments.
The result? A smile that looks and feels natural, allowing patients to eat, speak and smile with confidence.
How does the All-on-4 procedure work?
The procedure is based on the principle of “immediate loading”, which allows a provisional prosthesis to be fixed shortly after the implants are placed, usually within a few days, once it has been customized.
The titanium implants integrate with the bone as it regenerates and remodels around them, becoming dense and stable and creating a solid foundation.
The tilted rear implants distribute chewing forces evenly, reducing the risk of failure and allowing a faster recovery.
Studies show a long-term success rate of over 95%, making All-on-4 a reliable option for thousands of patients every year.
The stages of the procedure: a step-by-step guide
The All-on-4 process is carefully planned to keep discomfort to a minimum and achieve good results. Here are the main stages, first in brief and then in detail:
- Initial consultation: a full assessment of your oral health.
- Planning and preparation: using advanced technology.
- Implant placement: the surgical procedure itself.
- Fitting the provisional prosthesis: immediate function.
- Healing period: integration with the bone.
- Completion with the final prosthesis: the fixed, implant-supported restoration.
In the first stage, the initial consultation includes 3D X-rays (CBCT) and intraoral scans to create a digital model of the jaw. It takes about an hour and helps identify any problems, such as infections or insufficient bone density.
Next comes implant placement, carried out in a minimally invasive way under local anesthesia or sedation. In a single 2–4 hour session, the dentist extracts any remaining teeth (if needed) and places the four implants. The provisional prosthesis, customized for good function, is fixed within a few days, so patients quickly have a functional arch.
After 3–6 months of healing, once the implants have fully integrated with the bone, the final prosthesis is fitted, customized for aesthetics and comfort. The whole process can be completed in less than six months, compared with the years needed for traditional methods.
Main benefits of All-on-4
Why choose All-on-4? Here are the key advantages, summarized in bullet points for a quick read:
- Stability: the fixed prosthesis lets you chew harder foods with confidence, improving speech and nutrition.
- Natural appearance: the teeth look similar to real ones, restoring self-confidence and facial aesthetics.
- No extensive bone grafts: the technique makes efficient use of the existing bone, reducing costs and risks.
- Quick recovery: most patients return to their normal activities within a few days.
- Long-lasting: with proper care and regular checkups, implants can last for many years, according to long-term studies.
- Cost: usually lower than individual implants for the whole arch.
Beyond these benefits, All-on-4 improves quality of life. Patients report greater social confidence, because they no longer have to hide unstable dentures. A systematic review published in Clinical Oral Implants Research shows satisfaction of over 95% with fixed implant-supported prostheses such as All-on-4, compared with around 70% for removable dentures, after one year.
Who is eligible for All-on-4?
Not everyone is a suitable candidate, but the technique is adaptable. The typical candidate has no teeth left or teeth that cannot be saved, with enough bone at the front of the jaw. Eligibility factors:
- Aged over 18 (adults).
- Good general health, with no uncontrolled conditions such as diabetes.
- No harmful habits, such as heavy smoking.
If you have severe bone loss, further assessments may be needed. At Dental CATTED, our medical team carries out detailed tests to confirm eligibility.
Aftercare and possible risks
After the procedure, aftercare is essential for long-term success. Practical tips:
- Daily hygiene: brush the prosthesis as you would natural teeth, using soft toothbrushes and an antibacterial mouthwash.
- Regular checkups: visit the dentist every 6 months for professional cleaning.
- Diet: avoid hard foods for the first few weeks, then gradually return to a normal diet.
The risks are low (under 5% of cases for infection or rejection, according to clinical data), but they include infection, implant rejection or temporary discomfort. Factors such as smoking or poor hygiene can increase these risks – discuss them with your dentist.
