For patients who have substantial bone loss in the upper jaw
Zygomatic implants are an alternative to more traditional implants which involve drilling directly into the jawbone. Instead of doing this, the Zygomatic implants are much longer then these traditional implants. They are anchored in the upper jawbone, which is close to the dense zygoma bone. This difference in location means that Zygomatic implants can provide a secure foundation for your dental implants while traditional dental implants may not be possible. Where as people with deteriorated jaws may not be able to receive this surgery, advancements with Zygomatic implants means it can still be possible.
Zygomatic implants have been documented as an alternative for the rehabilitation of the atrophic posterior maxilla with both the classical two stage and immediate loading protocols.
Zygomatic implants avoid grafting and sinus lift procedures and therefore contribute to a shorter and more comfortable treatment. Further indications for zygomatic implants include failed conventional implant placement, failed sinus augmentation or grafting procedures, rehabilitation after tumor and trauma resections.
In the atrophic posterior maxilla, in general one zygomatic implant is placed on each side of the maxilla, in combination with 2-4 conventional implants in the anterior region.
For the totally resorbed maxilla, when placement of anterior implants is not possible the concept can be expanded by inserting 2 additional zygomatic implants in a more anterior position (Quad zygoma). Zygomatic implants nowadays are usually immediately loaded with a fixed bridge.
