Losing teeth is a more life-altering experience than it first appears. You can no longer eat what you want, you avoid smiling, you feel uncomfortable in public, and you start to withdraw from social situations. For many, a removable denture seems like the only affordable option, but the reality is that there are modern, fixed solutions that restore the functionality and aesthetic appearance of natural teeth.
On implants, or a fixed prosthesis on implants, using the All-on-4 and All-on-6 techniques, is one of the most effective methods for total rehabilitation of a dental arch. Instead of receiving an implant for each missing tooth, you receive a fixed prosthesis, supported by only 4 or 6 implants, which restores a complete, stable, and aesthetic set of teeth.
Toate-pe-4 și Toate-pe-6 sunt proceduri dentare implantare.
- There are total rehabilitation solutions for a dental arch with implants
- All-on-4 uses 4 implants, All-on-6 uses 6 implants
- A fixed prosthesis with 10-14 teeth is fitted onto the implants
- They are recommended for people who are completely edentulous or who haveadvanced periodontal disease
- The choice between the two techniques depends on bone density and location (maxilla or mandible).
When you need a fixed denture
The fixed teeth solution is recommended in a fairly specific number of situations. Basically, when there are no longer enough natural teeth to support a classic prosthetic work, or when existing teeth can no longer be saved.
The situations in which you need a fixed denture are the following:
- You've lost all your teeth (or nearly all of them)
- You wear a removable denture and would like a fixed solution
- You are suffering from advanced periodontal disease and are about to lose all your teeth.
- Your teeth are compromised and can no longer be saved by other treatments.
Dr Alexandru Ciucu, a dentist with a specialisation in implantology, at Dental Elite Clinics, explains in which situations each of the two techniques is recommended:
”This technique is suitable for those with very advanced periodontal disease or those who have lost all their teeth. When dealing with better mineralised bone, we can use the All-on-4 technique, which involves inserting four dental implants. When dealing with less mineralised or slightly softer bone, as we say, it is advisable to use more posts, which will provide greater stability. Therefore, generally, for the lower jaw, when we have better mineralised bone, we use the four-implant technique, but we can also use six for better stability. However, for the upper jaw, the maxilla, we almost always use the All-on-6 technique, with six dental implants.
What is All-on-4, the fixed denture on 4 implants
All-on-4 is a method of total rehabilitation of the lower dental arch (mandible) whereby a fixed prosthesis with 10-14 teeth is fitted onto just 4 strategically placed implants in the bone, and has become, over time, the global standard for the rehabilitation of totally edentulous patients.
The particularity of this method lies in the way the implants are positioned: two are inserted vertically in the frontal area of the arch, where the bone is usually denser and better mineralised, and the other two are inserted tilted (at an angle of up to 45 degrees) in the posterior area. This tilt makes the difference. In practice, it avoids sensitive anatomical areas (maxillary sinuses, inferior alveolar nerve) and makes the most of the available bone, without the need for bone grafting in many cases.
The fixed teeth solution with 4 implants is particularly recommended for the mandible (lower arch), where the bone is naturally denser. It is also a more financially accessible option than All-on-6 and involves a less extensive surgical intervention.
What is All-on-6, the fixed prosthesis on 6 implants
All-on-6 is a variation of the same solution, but with 6 implants instead of 4. The two additional implants are positioned in the lateral area of the upper arch (maxilla), offering stronger support for the fixed prosthesis.
The advantages of six implants are clear: chewing forces are distributed more evenly along the entire length of the arch, pressure on each individual implant decreases, and long-term stability increases. Furthermore, if, for various reasons, one implant does not integrate perfectly, the other five can support the prosthesis without problems.
Rehabilitation with 6 implants is particularly recommended for the maxilla (upper arch), where the bone is typically less dense than in the mandible. It is also the preferred choice for patients with bruxism (teeth grinding), those with high occlusal forces, or those who desire maximum long-term security.
The All-on-4 / All-on-6 (Fixed Teeth) Procedure Stages
Total rehabilitation with dental implants is a complex procedure, involving several stages over several months. Here's what you can expect at each step.
1. Consultation and planning
Everything begins with a detailed consultation. The dentist assesses the state of the oral cavity, takes a 3D X-ray (CBCT), and analyses bone density and volume. Based on this data, they decide between All-on-4 and All-on-6 and digitally plan the exact position of each implant.
2. Further treatments
If there are any compromised teeth remaining, they must be extracted before or during the same session as implant placement. In some cases, a professional cleaning is also necessary, and any active infections must be treated before the procedure.
3. Surgical intervention
Under local anaesthetic, the dentist, who is competent in implantology, inserts the 4 or 6 implants into the bone, according to the digital plan. The procedure usually takes 2-3 hours for one arch and is completely painless. Thanks to modern technologies, the procedure is predictable and recovery proceeds without major complications. The abutments are also fitted during the same procedure.
4. Application of the temporary prosthesis
Shortly after surgery (most often on the same day or the next), a temporary prosthesis is fitted onto the implants. With it, you can speak, eat soft foods, and you are fully functional. This prosthesis is used during the healing period.
5. Osseointegration period
Implants need 3-6 months to fully integrate with the bone. During this time, you wear a temporary prosthesis and attend regular check-ups so the doctor can monitor the healing process.
6. Fitting of the definitive fixed prosthesis
After confirming osseointegration, the final impression is taken and the definitive fixed prosthesis is made. This can be made of zirconia, porcelain-fused-to-metal, all-ceramic, or porcelain-fused-to-zirconia, depending on budget and preference. The final fixed prosthesis is fitted onto the implants and becomes your long-term teeth.
7. Checks and care
Fixed teeth solutions are not cleaned after application. Check-ups every 6 months, professional cleaning, and rigorous oral hygiene at home are required to keep implants healthy in the long term.
Advantages of full mouth restoration
Total rehabilitation with dental implants is a complete transformation of everyday life. The discomfort, embarrassment, and limitations caused by tooth loss disappear, and life returns to normal.
Dr. Alexandru Ciucu, a dentist at Dental Elite Clinics, describes what changes for patients who opt for fixed dentures:
Our pacients report feeling younger and more confident than ever before. Fixed dental prostheses give you a stable smile for many years to come, improving oral health.
This is how fixed implant-supported teeth can transform your smile:
- Improving digestion and overall health – effective chewing is the first step to proper digestion
- Elimination of bad breath – lack of bacteria in problem areas reduces halitosis
- Combating periodontal disease – by removing compromised teeth and infected tissue
- preventing other oral problems – bone resorption stops, and tissues remain healthy
- improving aesthetic appearance – a harmonious smile, with natural-looking teeth
- boost in self-confidence – you can talk, laugh, and eat without holding back
- stability – fixed prosthetics do not move, do not fall out, and do not cause you discomfort
- Functionality – you can eat almost any type of food, just like when you had your natural teeth
- long-term results – with correct care, implants last for decades
„An unhealthy smile can greatly lower our self-confidence and our general outlook on life; we can no longer eat properly, we can no longer smile, and we feel embarrassed to speak to people or our friends, but at Dental Elite we have the solution,” adds Dr. Ciucu.
Dental Elite Packages for Fixed Dentures on Implants
At Dental Elite, you'll find three packages dedicated to total implant rehabilitation, each built around a premium implant system, with the temporary fixed prosthesis included in the price. The decision between them is made together with the implantologist, depending on the CBCT evaluation, your budget, and your long-term goals.

FAQ – Frequently asked questions about All-on-4 and All-on-6
How many teeth are placed on 6 implants?
A fixed prosthesis is fitted onto 6 implants, typically encompassing 12-14 teeth. Essentially, this constitutes a complete dental arch, restoring full chewing functionality and the aesthetic appearance of natural teeth. In some cases, the number of teeth may vary slightly depending on individual anatomy.
How many teeth are placed on 4 implants?
A fixed prosthesis with 10-12 teeth is fitted onto 4 implants. This also covers the entire dental arch but is slightly shorter in the posterior area than the 6-implant option, to avoid overburdening the four supports.
Care este diferența principală între All-on-4 și All-on-6?
The number of implants. All-on-4 uses 4 implants, All-on-6 uses 6. The practical difference is that All-on-6 distributes chewing forces more evenly and is recommended for less dense bone (usually the upper jaw). All-on-4 is a more affordable and less invasive option, mainly recommended for the lower jaw.
Does the procedure hurt?
The procedure is carried out under local anaesthetic or, on request, with sedation. You will not feel any pain during the procedure. After the procedure, minor discomfort may occur, which can be managed with anti-inflammatory medication prescribed by your doctor.
How long does the treatment take from start to finish?
From the first consultation to the final prosthesis, the process takes between 3 and 6 months. Most of this time is needed for the osseointegration of the implants. Throughout this period, you will wear a functional temporary prosthesis.
How long does a dental implant take?
With correct care, implants can resist for decades, sometimes for life. It is important to attend regular check-ups, have professional cleaning, and maintain rigorous oral hygiene at home.
Can I eat normally after All-on-4 or All-on-6?
Yes. After the final prosthesis is fitted, you can eat almost any type of food. For the first few months, until osseointegration, a soft diet is recommended. After that, you can return to a varied diet.
Is bone augmentation needed?
Not always. One of the great advantages of All-on-4 and All-on-6 techniques is that, by angling the implants, the need for bone augmentation is avoided in many cases. The decision is made after a CBCT scan.
Can I have All-on-4 if I have gum disease?
Yes. In fact, the fixed teeth solution is especially recommended for patients with Periodontal diseaseYes. In fact, the fixed teeth solution is especially recommended for patients with Periodontal disease, where the teeth can no longer be saved. Before the implants are inserted, the infection must be completely treated, and the compromised teeth are extracted.
How much does a fixed prosthesis on 4 implants and a fixed prosthesis on 6 implants cost?
Prices vary depending on the clinic, the type of final prosthesis (zirconium, porcelain fused to metal, ceramic) and any additional procedures. Details can be found in the pricing section above.
Are there any risks or complications?
As with any surgery, there are minimal risks: infection, bleeding, incomplete integration of an implant. With correct digital planning, experienced doctors, and adherence to post-operative recommendations, these risks are very small.
What maintenance does a full mouth restoration require?
Rigorous oral hygiene (brushing, special implant dental floss, oral irrigator), 6-monthly check-ups and regular professional cleanings. Just like natural teeth, implants require long-term care.
