The All-on-4 dental implants

The All-on-4 dental implants

The All-on-4 dental implants are designed for patients with complete or partial adentia and are used in cases of bone deficiency. This method makes it possible to restore the function of the jaw system at a relatively low investment of time and money.

With this method, the requirements for the condition of the jawbone are significantly reduced. With the All-on-4 implants, the two outer artificial roots are implanted at an angle of 30-45° and the two middle roots are implanted perpendicular to the dentition.


  • there is no need to involve the maxillary sinuses, which in turn often precludes an upper jaw augmentation surgery;
  • a competently planned and lab-processed design enables an even distribution of the load on the inserted implants;
  • this rehabilitation is more expensive than a removable denture, but the all-on-4 design ensures a good quality of life because there is no need to remove it before heading to bed and it is firmly anchored by the implants.

Reasons to prescribe the All-on-4 implants

The All-on-4 implants are a modern method that in most cases does not require any additional surgery.

Dental restoration with this technology shall be indicated in the following cases:

Total adentia is a complete absence of teeth, parts of the jawbone are atrophied, have lost their original volume.

Partial adentia is a loss of a significant number of teeth; the remaining teeth are loose and cannot be used as a support for a normal bridge.

Periodontitis is an inflammation of the periodontal tissues and weakening of a ligamentous apparatus that may lead to tooth loss, and bone degeneration. There is not enough bone to place a large number of implants.

Advantages of the method

Alternative to osteoplastics

During treatment, the doctor treats areas with minimal bone resorption, as well as deep layers. This allows dental implants to be inserted without the need for a bone graft. If the upper jaw bone has no volume and the maxillary sinuses are extremely close, the All-on-4 will be effective.

A perfect smile

For temporization, we use acrylic overdenture restorations. The new teeth and artificial gum look as natural as possible.

Full functionality of the teeth

The patient will be able to chew immediately after the treatment with the new teeth, habituating to new teeth and gradually increasing the load. Within 21 days, the chewing function could be completely restored.

Bloodless method

The surgery is carried out using a prefabricated surgical template. This way, the implants are implanted in the bone tissue at the correct angle with minimum trauma.

The disadvantages of the All-on-4 are the increased load on the jaw and a possible decrease in the lifespan of the implants. This is because we replace 16 teeth with only four implants.

As with any method, there are contraindications and risks:

  • serious liver and kidney diseases;
  • uncompensated autoimmune conditions;
  • some blood disorders;
  • endocrine disorders.

Preparation for surgery

The All-on-4 implants provides for detailed planning of the surgery. We will perform detailed diagnosis, including a computer tomography, scanning of the jaws, calculation of future loads and making of templates and temporaries for each step of subsequent treatment.


On the day of surgery, we will place all implants. If indicated, we will extract certain teeth and restore soft tissues beforehand. We will place implants and a temporary denture. The duration of the surgery is 1-3 hours.


After tissue healing, which is about one week, we will place a temporary denture for long-term use. A dental bar is used for strength. Crowns are usually made of metal-reinforced plastic and the artificial gum is made of acrylic. Temporary denture can be worn from 4 months to a year. Then it shall be replaced by a permanent one, which is made from stronger materials that are adapted to the situation.

It is important to note that in case of sufficient bone volume, the doctor may recommend the All-on-6 option because the prosthetic structure with more implants will provide greater security and durability.

Price of the implants

The cost of the All-on-4 implants depends on: the diagnosis required and the amount of preparation; number of teeth that need to be extracted; models of dental post; additional consumables (for example, a surgical template shall be paid separately); type of fixed denture.
