Losing teeth does not mean losing your smile. Thanks to the All-on-4 and All-on-6 techniques, it is possible to rehabilitate the entire dental arch with just four or six implants, restoring function, aesthetics, and confidence — in a single procedure.
At OnlySmile in Ponta Delgada (São Miguel, Azores), we combine digital technology, precise diagnosis, and clinical experience to offer fixed total rehabilitations that are comfortable and personalized. The result? A complete, stable, and natural smile, often in less time than you might imagine.

1. What is All-on-4 and All-on-6
All-on-4 and All-on-6 are advanced dental implant techniques that allow for the replacement of all teeth in an arch (upper or lower) using only four or six implants.
These implants support a fixed prosthesis — meaning the patient leaves the clinic with fixed, stable, and functional teeth.
The concept was developed to offer an effective, less invasive solution with faster recovery.
At OnlySmile, we assess the type of bone, overall health, and patient expectations to determine the best option.
2. How the technique works
The secret of All-on-4 lies in the strategic positioning of the implants: two anterior vertical and two posterior inclined up to 45°, maximizing the available bone volume.
The All-on-6 follows the same logic but with two additional implants, ensuring greater distribution of masticatory load and extra stability.
This approach avoids bone grafts in most cases and allows for provisional fixed teeth on the same day of surgery — the so-called “immediate load.”
3. Differences between All-on-4 and All-on-6
While both techniques offer excellent results, there are subtle differences that help define which is most suitable for each case.
All-on-4 — efficiency with fewer implants
In this approach, four implants are placed per arch: two anterior in the vertical position and two posterior inclined up to 45°.
It is indicated for patients with moderate bone loss, allowing for the avoidance of grafts in most cases.
It ensures excellent stability and aesthetics with a more accessible investment, being a highly sought-after solution for quick and predictable complete rehabilitations.
All-on-6 — reinforced stability and greater load distribution
Uses six strategically distributed implants, providing greater support and durability.
It is indicated for patients with sufficient bone quantity who seek an even more robust rehabilitation.
Allows for better distribution of masticatory force, increasing comfort and prosthesis longevity.
In summary:
- All-on-4 is ideal when there is less bone volume and when an effective and affordable solution is sought.
- All-on-6 is recommended when there is good bone density and the goal is maximum stability and durability.
At OnlySmile, the choice is made after detailed 3D analysis, always ensuring a balance between function, aesthetics, and comfort.
4. Advantages over removable dentures
- Fixed and stable solution: no displacements when speaking or chewing.
- Better aesthetics: natural and proportional appearance.
- Greater comfort: no gum pain or friction sores.
- Bone preservation: prevents natural jaw resorption.
- Ease of chewing and speaking.
- Increased self-esteem and quality of life.
All-on-4 returns the sensation of having natural teeth to the patient, allowing them to eat, laugh, and speak with complete confidence.
5. Treatment steps at OnlySmile
- Evaluation and 3D diagnosis — tomography and digital planning.
- Virtual surgical planning — precise definition of implant positioning.
- Guided surgery — implant placement with minimal invasiveness.
- Immediate provisional prosthesis — the patient leaves with fixed teeth on the same day.
- Bone integration period — about 3 to 6 months.
- Definitive prosthesis — made with durable materials and natural aesthetics.
Each step is accompanied with attention and transparency.
The patient is always informed about the plan, timelines, and necessary care.
6. Digital technology and 3D planning
The success of All-on-4 depends on rigorous planning.
At OnlySmile, we use digital smile planning and 3D tomography to ensure absolute precision.
The surgery is performed with customized surgical guides, digitally designed, reducing time, pain, and risk of error.
This method also allows for the aesthetic result to be predicted before the intervention.
7. Materials and durability
The prostheses used can be:
- Reinforced acrylic (provisional).
- Ceramic (for superior aesthetics).
- Monolithic zirconia (maximum durability and resistance).
With proper maintenance and periodic reviews, All-on-4 and All-on-6 rehabilitations can last more than 20 years.
At OnlySmile, all materials are certified and biocompatible, ensuring long-term safety and comfort.
8. Recovery and post-operative care
Recovery is surprisingly quick, especially with minimally invasive techniques.
Most patients return to their usual routines within a few days.
During the first weeks, a soft diet and good oral hygiene are recommended.
The team at OnlySmile accompanies each step — from post-operative care to full prosthesis adaptation.
9. Ideal candidates for All-on-4 / All-on-6
This treatment is indicated for:
- Patients without teeth or with severely compromised teeth.
- Unsatisfied users of removable dentures.
- People with moderate bone loss.
- Those seeking a fixed and long-lasting solution.
Even in cases of lower bone density, All-on-4 is often viable without the need for grafts — making it accessible to more patients.

Frequently Asked Questions
1) What is All-on-4?
It is a total rehabilitation technique with only four implants per arch, supporting a fixed prosthesis.
2) What is the difference between All-on-4 and All-on-6?
All-on-6 uses two additional implants, providing extra stability and durability.
3) Does the treatment hurt?
No. It is performed under local anesthesia and, if necessary, with conscious sedation.
4) Can I leave the surgery with fixed teeth?
Yes, in many cases we place a provisional fixed prosthesis on the same day.
5) Is a bone graft necessary?
In most cases, no. The inclined positioning of the implants avoids this necessity.
6) How long does the treatment last?
With proper care, it can last more than 20 years.
7) How is daily cleaning done?
With a soft brush, interdental brush, and periodic oral hygiene reviews.
8) Is the result natural?
Yes. The prostheses are designed based on facial shape and digital planning.
9) Can I chew normally?
Yes. After the integration phase, the patient fully recovers masticatory function.
10) Where can I have All-on-4 done in the Azores?
At OnlySmile in Ponta Delgada (São Miguel), with 3D technology and an experienced team.
