If you have been told you have little bone and can not bear implants, read this article.
Dental implants are artificial roots usually made of titanium that are anchored in the bone of the jaw. Over these artificial roots the prostheses are fixated.
Dental implants have a determined length and diameter, therefore a minimum amount of bone is needed in order to be anchored to the jaw.
If the available bone in the jaw is very little (we must remember that losing teeth due to periodontal disease will lead to resorption of the bone that surrounds the roots of the teeth) we only have the option to graft bone from another area of the body.
In the case of extreme resorption of the upper jaw and to avoid the need of bone grafts, zygomatic implants are an option. These are very long implants that are anchored in the maxillary zygomatic bone (cheekbone).
The use of this technique is an excellent alternative in the treatment of edentulous patients with low bone mass in the maxilla. For these patients represents a hope in their treatment, enabling making a fixed prosthesis, replacing removable dentures on the same day or the day after surgery.
Advantages of zygomatic implants over bone grafts
- The big advantage is that with zygomatic implants the process is much faster, no timeouts, a fixed provisional prosthesis is made within the first 24 hours. In the case of bone grafts, time is needed to allow the maturation of the graft, which makes the placement of permanent teeth to delay almost a year.
- Has lower cost.
- The post-operative time is reduced. Only one intervention is required. In cases of bone grafts, at least 2 interventions are required. The patient will only notice swelling and bruising during the first days and mild discomfort.

How is the treatment with zygomatic implants performed?
It is part of a comprehensive preliminary study of the upper jaw, with the latest 3D technology.
With the jawbone and three-dimensional CT study we can get the most out of the bone of the patient.
Clearly, further study of the aesthetics of the patient is also required: photographic analysis and study models. Once the diagnosis is done, the treatment plan is explained to the patient. Zygomatic implants normally are complemented with 2 or more conventional implants in the anterior region.
If very little bone is present in the anterior area, four zygomatic implants can also be placed.
