All on 4

Starting from


The "All-on-4" method is a dental implantation technique used to replace an entire dental arch (either upper or lower) using only four dental implants. This technique allows patients with a significant number of missing teeth to obtain a strong, durable, and natural-looking prosthetic replacement.



Candidates for the "All-on-4" method typically include individuals with severe dental issues, such as patients who have lost a significant number of teeth or have substantial damage to their existing teeth. Additionally, candidates should be in good overall health to undergo the surgical procedure.


Preparation for the treatment involves a detailed consultation with an oral surgeon or implantologist to assess the patient's oral condition, plan the treatment, and select the appropriate materials and prosthetic design. During the preparation, patients may need to undergo X-rays and other diagnostic tests to precisely determine the location and angle of the implants.


The actual "All-on-4" treatment involves the following steps: 1. Surgical procedure, which includes the placement of four dental implants in selected positions in the patient's jaw. These implants serve as replacements for tooth roots. 2. Healing phase, which lasts several months. During this time, the implants integrate with the jawbone, creating a sturdy anchor for the prosthetic replacement. 3. Fabrication of the prosthetic bridge, which consists of teeth and is attached to the four implants. The bridge is customized to match the patient's appearance and bite.


The results of "All-on-4" treatment include a stable, functional, and aesthetically pleasing tooth replacement. Patients will be able to chew food without difficulty and regain a beautiful smile. Additionally, the prosthetic bridge will look and feel very natural.


Precautions after the treatment include regular oral hygiene maintenance and following the doctor's instructions to ensure the long-term successful use of the implants and prosthetic bridge. Regular dental check-ups are also crucial for monitoring oral health.

What is All-on-4?

All-on-4 is a method based on a prosthetic bridge that is fixed with screws on four specially placed implants. It represents a permanent solution for completely toothless patients, who have lost all teeth in the upper or lower jaw.

How long does the whole setup process take?

The duration of the entire process is individual and depends on the condition of the oral cavity. Implants are placed in one visit, followed by the process of osseointegration (implant joining the bone). During the process of osseointegration, the patient has a temporary prosthetic work, and when the union is completed, the temporary work is replaced by a permanent one.

In which cases is All-on-4 not a good option?

All-on-4 is not a good option if you have healthy teeth. This method is only suitable for completely edentulous patients. Also, if you have a weak immune system, All-on-4 is not a good option because the body can reject the implants.

What if I'm not a candidate for All-on-4?

If you have healthy teeth and are therefore not a candidate for All-on-4, we recommend crowns or individual implants.

What is the durability of implants?

With good oral hygiene and regular visits to the dentist, the durability of dental implants is lifelong.

Is this procedure safe?

This procedure is performed by dentists and oral surgeons who have years of experience behind them and thousands of satisfied patients. It is completely safe and minimally invasive.

Do I have a warranty on the implants?

Patients have a lifetime warranty on implants.

How long does it take for the oral cavity to get used to implants?

A few days after installation, the patient gets used to the installed implants and temporary prosthetic work. During the osseointegration process, it is recommended to eat softer food. After the placement of permanent prosthetic work, the patient can eat anything.

Are All-on-4 dental implants suitable for everyone?

All-on-4 dental implants can be a suitable solution for many individuals who have lost all or most of their teeth and have good oral and overall health. However, a thorough evaluation by a dental professional is necessary to determine if you are a suitable candidate for the procedure.

Is the All-on-4 procedure painful?

The All-on-4 procedure is performed under local anesthesia, ensuring that you won't feel any pain during the surgery. After the procedure, some discomfort and swelling may occur, but this can typically be managed with over-the-counter pain medications and cold compresses. Your dentist will provide you with specific post-operative instructions to help minimize any discomfort during the healing process.
