All-on-Four concept

The All-on-Four concept® is an innovative method for restoring an edentulous jaw with fixed dentures. It is based on the use of just four implants. The term "All-on-Four" is protected by trademark law and was developed by the renowned implant manufacturer Nobel Biocare in collaboration with Dr. Paolo Malo in Lisbon.

Advantages of the concept

The concept utilizes the often sufficient bone in the anterior region of edentulous jaws to securely anchor implants. This allows the implants to be inserted in just one session, which speeds up the healing process and reduces overall costs.

Technical details

Four implants: Two implants are inserted straight, the rear two at a 45-degree angle.

Advantages: This method enables a safe and efficient restoration of the edentulous jaw and represents a cost-effective and time-efficient alternative to conventional implant procedures.

Treatment steps

Preliminary examination: medical history and digital volume tomography (DVT) for planning.

Implantation: Removal of the teeth to be replaced and anchoring of the implants. The procedure can be performed under general anesthesia or light sedation if desired.

Temporary restoration: A digital scan is made and the patient receives a fixed temporary restoration for the transition period.

Final prosthesis: After 3-6 months, the temporary prosthesis is replaced by the final prosthesis.

Patient information

Patients who are interested in the All-on-Four method are given detailed advice. All questions about the treatment, the jawbone, anesthesia and costs are clarified. Together we will discuss whether immediate dental implants are suitable in your case and explain the procedure as well as the risks and benefits of the procedure.

This treatment can also be carried out gently with the "One time Clever" concept.

All on Four Concept Innovative

In the posterior region, the bone supply is usually unfavorable for implant placement. The maxilla is difficult with the maxillary sinuses (maxillary sinus > takes up a lot of space). Therefore, direct implant placement in the molar region (from tooth 6) usually requires bone augmentation (sinus lift).

In the end it is again crowns or bridges on artificial tooth roots

Bone loss in the mandible can make it difficult to place implants, especially in the posterior region. In such cases, according to conventional doctrine, it can be difficult to securely fix a fixed prosthesis on implants. The "all on four" concept usually uses implants longer than 15mm. this is

Compared to conventional implants, which are usually 9-13 mm long, our longer implants are a significantly better option. They feature the ability to be loaded immediately, which guarantees a stable and long-lasting solution for missing teeth. The "All on Four" concept often allows for a faster and more cost-effective procedure compared to traditional implant procedures. For this reason, many people who have lost multiple teeth choose this popular choice to provide a reliable solution for their dentition. The use of longer implants improves stability and longevity for missing teeth.

The oblique implantation of the posterior (distal) implants requires precise positioning, which usually requires 3D planning. This 3D planning makes it possible to place the implants with millimeter precision using a 3D drilling template or navigation. Experts have made the "All on Four" concept widely available after long discussions due to its success. Other implant manufacturers also offer special abutments for their systems, all of which enable restoration with 4 implants (including 2 obliquely placed posterior implants). This concept provides patients with a safe and durable solution for their tooth replacement.

"All on 4" - Solid teeth in one day

With our "Fixed teeth in one day" program and the All-on-4 method, we can significantly speed up the complex process of full restoration with dental implants. The All-on-4 method allows us to build a complete row of teeth on just four dental implants.

We inform our patients in a detailed preliminary consultation, which includes a preliminary examination (including medical history and DVT/digital volume tomography), in order to inform them in detail about the treatment. If necessary, we remove the teeth to be replaced and anchor the implants firmly in the jawbone. We perform this procedure under general anesthesia or light sedation, if desired. After implant placement, we perform a digital scan of the current situation.

The patient temporarily receives a fixed temporary denture. After the treatment, the patient can go home with this until the dental implants have grown in completely. We replace the temporary denture after about 3-6 months with the final fixed denture made with the help of the post-implant scan.

Patients interested in the All-on-4 method are given detailed advice on dental implantation by the treating dentist and team. We will answer all questions about the dental implant and the treatment, the jawbone, the anesthesia and, of course, the costs. In the office, we will discuss together whether immediate dental implants are suitable and whether they should be placed in your case. It is important that we consider all factors and discuss all questions openly in order to make the best possible decision for your dental health. If immediate dental implants are being considered, we will explain to you exactly how the procedure works and what the risks and benefits are.
