A particular use
Some people have conditions that prevent them from benefiting from traditional dental implants in the upper arch. The main problem is an unsatisfactory quality and/or insufficient quantity of alveolar bone (the bone of the jaw where the teeth are located) in the upper jaw into which conventional implants are usually inserted.
Technological advances have led to the emergence of a new type of dental implant for the maxilla (upper jaw), called zygomatic implants. They are called that because they are inserted into the zygomatic bone; humans have two zygomatic bones that are located on either side of the jawbone, next to the sinuses located near the nose. These bones are easily visible on a face, as they are also responsible for the appearance of the cheekbones.
Not surprisingly, the main limitation of zygomatic implants is that they can only be used in the upper jaw, since anatomically speaking, there is no zygomatic bone adjacent to the mandible. In the event of atrophy of the lower alveolar bone, another treatment plan must therefore be proposed to the patient for his or her lower teeth.

Installation of zygomatic implants
Zygomatic implants are significantly longer than conventional implants because they fit into bones that are higher than the jawbone.
The use of zygomatic implants is often combined with the installation of conventional implants in the jawbone as part of the fixation of a dental prosthesis so that it is more stable in the mouth. Typically, two zygomatic implants and two to four conventional implants are required to complete the structure necessary for the placement of the dental prosthesis.
In cases where bone resorption is very important, four zygomatic implants can be used, in which case no conventional implants are required.
A recent technology
Zygomatic implants are quite recent: their first use on a patient dates back to 1989.
They were invented by Professor Per Ingvar Brånemark after numerous studies on skull bones to determine the best alternative to implants inserted in the jawbone.
