What are All-on-4 and All-on-6 implants?
All-on-4 and All-on-6 dental implants are modern solutions for the complete restoration of a dental arch, for patients who have lost all their teeth or are about to replace them because of advanced conditions. Instead of one implant for each missing tooth, the entire fixed restoration is supported by just 4 or 6 dental implants placed strategically in the upper or lower jawbone.
The concept aims to achieve fixed, stable and functional teeth, in many cases reducing the need for additional procedures such as bone grafting. After the implants are placed, a temporary restoration is fitted, and once the healing period is over it is replaced with the final restoration, made for the most natural look and optimal function.
The difference between All-on-4 and All-on-6
Both All-on-4 and All-on-6 have the same goal: replacing a complete arch with a fixed restoration on implants. The difference lies in the number of implants used and the clinical indications for each treatment. The choice is not made by preference, but according to the available bone volume, the distribution of chewing forces and the particulars of each patient.
All-on-4
The All-on-4 system uses four dental implants to support a complete arch. The two rear implants are placed at an angle so as to make the best use of the existing bone. For this reason, the treatment is often recommended for patients with moderate bone loss, as it can reduce or eliminate the need for bone grafting.
All-on-6
The All-on-6 system uses six dental implants, which allows a more even distribution of chewing forces and gives extra support to the prosthetic restoration. It is usually recommended for patients with sufficient bone volume, where the doctor considers that two additional implants can bring a long-term advantage.
| Feature | All-on-4 | All-on-6 |
| Number of implants | 4 dental implants | 6 dental implants |
| Recommended for | Patients with complete tooth loss and reduced or moderate bone volume | Patients with complete tooth loss and sufficient bone volume |
| Distribution of chewing forces | Very good | More even thanks to the two additional implants |
| Need for bone grafting | In many cases it can be avoided | Depends on the amount of bone available and the treatment plan |
| Stability of the restoration | Excellent | Excellent, with extra support for certain clinical cases |
Who is a candidate for All-on-4 or All-on-6?
All-on-4 and All-on-6 treatment is recommended for people who have lost all the teeth in an arch or whose teeth are beyond saving and who need a complete restoration. Following the consultation and imaging investigations, the doctor decides whether this solution is suitable for your situation.
You may be a suitable candidate if:
- you have lost all the teeth in your upper jaw, lower jaw or both arches;
- you wear a removable denture and would like a fixed solution;
- you have compromised teeth because of gum disease or extensive decay;
- you have a sufficient amount of bone or can benefit from a solution adapted to your situation;
- your general health allows the procedure to be carried out.
The final decision is always made after the specialist consultation, clinical examination and analysis of the 3D investigations.
Benefits of All-on-4 and All-on-6 treatment at Giadent Smile
At Giadent Smile, treatment is not just about placing implants, but a complete plan based on modern technology, premium materials and careful planning for predictable long-term results.
A solution for patients with bone loss
In many situations, the All-on-4 concept makes efficient use of the existing bone thanks to the strategic positioning of the implants. As a result, some patients can avoid additional bone grafting, shortening and simplifying treatment.
Bredent Fast and Fixed system
At Giadent Smile we use the Bredent Fast & Fixed system, an internationally recognised concept for fixed restorations on implants. It makes it possible to achieve a stable restoration with excellent function and aesthetics, designed to deliver predictable results and long-term comfort.
3D digital planning before the procedure
Every treatment begins with imaging investigations and 3D digital planning. Analysing the bone volume and simulating the position of the implants allows a precise procedure tailored to the particulars of each patient.
International implant passport and manufacturer’s warranty
After treatment, each patient receives the international implant passport, a document containing all the information about the implants used. In addition, the implants come with the manufacturer’s warranty, under its terms and conditions.
Stages of All-on-4 and All-on-6 treatment at Giadent Smile
Treatment is planned in detail so that every stage takes place safely and with predictable results.
-
Consultation and treatment plan
The first stage includes the specialist consultation, clinical examination and imaging investigations (CBCT). Based on these, the doctor decides whether All-on-4 or All-on-6 is the best solution and presents you with the complete treatment plan.
-
Placement of the dental implants
The procedure consists of placing the 4 or 6 dental implants in carefully planned positions. It is carried out under local anaesthetic and, in some situations, may be combined with any necessary extractions.
-
Fitting the temporary restoration
Depending on the particulars of the case, a temporary restoration is fixed in place after the procedure, so you can have fixed teeth from the first few days and get through the healing period more easily.
-
The osseointegration period
Over the following months, osseointegration takes place, in which the implants fuse biologically with the bone. Keeping to regular check-ups and your doctor’s advice is essential for the success of treatment.
-
Making the final restoration
Once osseointegration is complete, the temporary restoration is replaced with the final one, made to offer function, comfort and an appearance as close as possible to natural teeth.
All-on-4 and All-on-6 in Sibiu: how the price is determined

Frequently asked questions
How long does the All-on-4 or All-on-6 procedure take?
The duration depends on the complexity of the case and the number of extractions required, but in general the treatment is carried out in a single surgical session. The doctor will give you an estimated time after the consultation and the CBCT scan.
All-on-4 or removable denture: what is the real difference?
The main difference is stability. An All-on-4 or All-on-6 restoration is fixed on implants and does not move when you speak or chew, offering greater comfort than a removable denture and a feeling closer to that of natural teeth.
Can I have All-on-4 if I lost my teeth many years ago?
Yes, in many cases it is possible. Even if the teeth were lost many years ago and there is bone resorption, the treatment can still be an option. The doctor will determine this after the clinical examination and analysis of the CBCT scan.
Which implant system do you use for All-on-4 and All-on-6?
At Giadent Smile we use the Bredent Fast & Fixed system, a modern concept for full-arch restoration on implants, recognised for its predictability and reliability in All-on-4 and All-on-6 treatments.
What risks or complications can occur after All-on-4?
As with any surgical procedure, the treatment may be followed by temporary swelling, discomfort or bruising. Following the doctor’s recommendations, attending regular check-ups and keeping up good oral hygiene significantly reduce the risk of complications.
Can smokers have All-on-4 or All-on-6 implants?
Yes, but smoking increases the risk of complications and can slow down osseointegration. The doctor will explain the recommendations for reducing or stopping smoking before and after the procedure to improve your chances of success.
Can I have All-on-4 if I have diabetes or osteoporosis?
In many situations, yes. If the conditions are well controlled and there are no medical contraindications, the treatment can be carried out. Each case is assessed individually, and sometimes the approval of your treating doctor may be needed.
How do I keep All-on-4 and All-on-6 restorations clean?
Daily hygiene is essential for keeping implants healthy. Brushing twice a day, using an oral irrigator and interdental brushes, together with regular check-ups and professional cleanings, helps maintain the results in the long term.
How is the price of an All-on-4 or All-on-6 treatment determined?
The price depends on the complexity of the case, the number of implants, the type of prosthetic restoration and any additional treatments required. After the consultation you will receive a complete treatment plan and a transparent quote.
How many clinic visits are needed if I travel from far away?
The number of visits varies according to the treatment plan, but they are organised to keep travel to a minimum. At Giadent Smile we try to group the key stages of treatment, and the visit schedule is set from the very beginning, for the convenience of patients from other towns or from abroad.
