All-on-4 dentures, full dentures with 4 implants, in three weeks
Introduction
Losing all teeth or struggling with an unstable removable denture can affect every aspect of daily life—from eating and speaking to social confidence. Many patients know that an implant‑supported solution is the right direction but are unsure which method best fits their needs. Among the modern full‑arch rehabilitation options, all‑on‑4 dentures stand out as a fast, predictable, and long‑lasting solution for complete tooth loss. This treatment concept allows the creation of a fixed, full‑arch restoration supported by only four implants, typically completed in about three weeks.
This article provides a clear, structured overview of how the All‑on‑4 method works, who it is recommended for, and why it has become one of the most trusted full‑arch implant solutions worldwide.
About the most common implant solutions
Modern implant dentistry offers several approaches, each designed for different clinical situations. The four most widely used categories include:
– immediate loading, one‑phase implants,
– traditional, two‑phase implants,
– All‑on‑4 technology,
– All‑on‑6 technology.
Each method has its own indications, but All‑on‑4 is specifically designed for full‑arch rehabilitation in cases of complete or near‑complete tooth loss.
What are All‑on‑4 dentures?
The All‑on‑4 concept provides a fixed, full‑arch restoration supported by four strategically placed implants. It is ideal for patients who want a stable, permanent solution without the compromises of removable dentures. Even if a few teeth remain, the method is still applicable when those teeth are no longer suitable for long‑term treatment.
The implant placement strategy is the key to the method’s success:
– two implants are positioned vertically in the anterior region,
– two implants are placed at an angle of approximately 45 degrees in the posterior region.
This configuration maximizes the use of existing bone, often eliminating the need for bone grafting. The result is a stable foundation capable of supporting a fixed, full‑arch bridge.
Who is a candidate for the All‑on‑4 solution?
All‑on‑4 dentures are recommended for patients who:
– have complete tooth loss and want a fixed, implant‑supported solution,
– have remaining teeth that require extraction due to decay or periodontal disease,
– have insufficient bone volume for traditional implants,
– want a fast, predictable rehabilitation with minimal downtime,
– are dissatisfied with the functional or aesthetic limitations of removable dentures.
This method is particularly beneficial for patients who want to avoid bone grafting and prefer a streamlined treatment process.
A closer look at the All‑on‑4 concept
The essence of the All‑on‑4 method is the placement of a fixed, 10–12 unit full‑arch bridge supported by four implants. The angled posterior implants allow the clinician to anchor into denser bone regions, improving stability and reducing the need for additional surgical procedures.
Why angled implants matter
Angled implants:
– reach stronger bone areas,
– reduce the need for sinus lift or bone augmentation,
– shorten treatment time, – lower overall costs,
– improve long‑term stability.
This approach allows patients to receive a fixed temporary restoration immediately after surgery, significantly enhancing comfort during the healing period.
The 5 key benefits of All‑on‑4 technology
1. Absolute stability – A fixed, implant‑supported restoration eliminates the need for adhesives and provides stability comparable to natural teeth.
2. Aesthetic excellence – The final restoration is custom‑designed to match the patient’s facial proportions and aesthetic expectations, resulting in a natural‑looking appearance.
3. Restored chewing function – A stable, full‑arch restoration allows patients to enjoy a wider range of foods, improving digestion and overall well‑being.
4. Psychological comfort – A fixed restoration eliminates the insecurity associated with removable dentures, helping patients regain confidence in social and professional situations.
5. Accelerated treatment protocol – Thanks to immediate loading, patients leave the clinic with a fixed temporary restoration on the day of surgery. The full treatment process—including the final denture—typically takes around 20 days.
The All‑on‑4 dentures process (3‑step, ~20‑day protocol)
The All‑on‑4 method follows a structured, three‑appointment protocol that ensures precision and predictable results.
First appointment – Surgical phase
– consultation and treatment planning,
– extraction of teeth unsuitable for further treatment,
– placement of four implants (with optional anesthesia).
A fixed temporary restoration may be attached immediately, depending on the clinical situation.
Second appointment – Post‑operative check‑up (approx. 7 days later)
– evaluation of implant stability,
– suture removal,
– impressions for the final fogsor.
This step ensures that the final restoration will fit accurately and function reliably.
Third appointment – Final restoration (approx. 10–12 days later)
– placement of the final porcelain or zirconia bridge,
– fixed, non‑removable restoration.
With optimal bone structure, the entire process—from surgery to final fogsor—takes about three weeks.
Frequently asked questions
Is the procedure painful?
The surgery is performed under local anesthesia, ensuring a painless experience. Mild post‑operative discomfort can be managed with standard pain medication. General anesthesia is available upon request.
How long is the recovery period?
The healing period is only a few weeks, the ossification process is 3-5 months. During the first few weeks, you should bite and chew carefully. It is not recommended to bite hard, eat hard foods, or strain your teeth in general.
What does the price include?
The treatment fee typically covers:
– four premium‑quality implants,
– the surgical procedure,
– the final screw‑retained denture.
A detailed treatment plan and cost estimate are provided during the consultation.
