Zygomatic implants

The zygomatic implant is a special implant with larger dimensions than conventional implants. Instead of anchoring to the maxillary bone in its totality, it anchors mainly in the zygomatic or malar bone which is located at the cheekbone level.
While the average size of the conventional implants is around 10mm, the zygomatic implants have a length between 40 and 50mm.

Which patients require zygomatic implants?

Zygomatic implants have a clear purpose, its meant for those patients that present severe atrophy of the upper maxilla and where the only option for conventional implants is placing bone grafts. This option is also valid but very lengthy and large number of surgical interventions are required.
The advantage of zygomatic implants is that they are placed within a single surgery and loaded at the very moment whereof the patient can leave the same day with his temporary fixed teeth.

How many Zygomatic implants are required to rehabilitate a toothless patient?

There are two types, according to degree of atrophy of the upper maxilla.

  • Moderate atrophy: It is seen in those patients that have lack of bone in the back área, but preserves enough bone in the former area to stabilize at least 4 conventional implants. In this case we can use 2 zygomatic implants + 4 standard implants which can be loaded in the first 48 hours.

  • Severe atrophy: It is noticed in those patients in which there is no bone at all, neither in the front or back area therefore it is not possible to place conventional implants without using bone grafts to reconstruct lost bone. In these cases, 4 zygomatic implants are used that which are loaded in the first 24 hours for the patient to mantain the aesthetics from the first moment.
