All-on-4 dental prosthetics

Modern dentistry uses many methods of prosthetics with complete loss of teeth or their absence, and one of the most popular is dental prosthetics on All-on-4 implants (all prosthetics on four implants).

What is All-on-4 prosthetics?

All-on-4 implants is a prosthetics method that allows to restore the entire dentition using only 4 implants. This greatly simplifies the operation, as well as shortens the recovery and rehabilitation of the patient. The all-in-four prosthetics technology was developed in 1998 by Dr. Paulo Malo, and since then, thousands of patients have successfully completed treatment using this method.

How are all on 4 implants installed?

4 dental implants are implanted into the jaw at a certain angle and distance, onto which a fixed bridge in the form of an arch (horseshoe) is then screwed. You can read more about types of prostheses and their categories in the previous article “Types of dental prostheses”.

Usually, 10 teeth are installed on such a prosthesis. This is enough to provide a beautiful smile, but not enough to restore chewing function. But it all depends on the situation of the patient. If it is possible to place the implants away from each other, then in this case, you can increase the number of teeth in the prosthesis to 12 or 14.

Benefits of All-on-4 implantation

  • Complete rehabilitation of the dentition on four implants;
  • There is no need for bone grafting and complex operations;
  • Short terms of treatment;
  • Excellent functionality, which is many times better than conventional prosthetics;
  • Reliable fixing thanks to screws;
  • High implant survival rate;
  • Preservation of the structure of the jaw;
  • Long service life;
  • High aesthetic indicators;
  • Lower cost of treatment compared to full implantation with partially or completely absent dentition.

In addition, prosthetics on 4 implants is the minimum number of implants to support a non-removable bridge prosthesis. In addition, all on 4 prosthetics is an excellent option both in cost and in traumatization compared with the installation of 14 implants or dental crowns.

Features of the installation of all-on-4 implants

There are also pitfalls in dental prosthetics on 4 implants, and they begin with the anatomy of the jaw and the presence of bone tissue. Unfortunately, due to the peculiarities of the structure of the jaw, not all patients can undergo prosthetics on 4 implants. This can be influenced by many factors that an implantologist-prosthetist will reveal during a detailed examination at a consultation.

It is worth remembering that 4 implants are the minimum number that can be set with a full loss of dentition. If you install 6 implants, then the risks of fracture of the prosthesis will be significantly reduced, and stabilization will also increase.

Cost of dental prosthetics on 4 implants

The cost of prosthetics All on 4 is affected by several factors, in particular, the condition of the oral cavity, structural features of the jaw, types of prostheses and implants. Also, a lot depends on the doctor and his experience. You can find out the full cost of All-on-4 prosthetics at a consultation with your doctor.
