Zygoma implants, sometimes called zygomatic implants, are different from conventional dental implants in that they are affixed in the zygomatic bone, not the maxilla. They can be used in situations when there is not enough maxillary bone, either in terms of quantity or consistency, to support a dental implant. Insufficient maxillary bone volume may result from a combination of maxillary sinus pneumatization and bone resorption. To guarantee proper implant survival, the normal implant placement in the posterior maxilla requires a bone height of about 10 mm. Increased bone volume can be achieved by sinus elevation and bone grafting techniques in cases when there is insufficient bone available. The drawbacks of bone grafting procedures in the jaws include the need for prolonged care, restrictions on denture wear, morbidity at the donor surgical site, and graft rejection.
