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. This approach may alleviate the need for significant grafting to enable implant placement in the posterior maxilla and allow implants to be placed into denser, more stable bone. Zygomatic implants, which have been used clinically for the past years in the treatment of the severely resorbed maxilla, allow implant placement to support fixed prosthetics.
Their usage can potentially shorten treatment time and reduce costs, as the need to wait for osseous graft maturation is eliminated. Guided surgical approaches are being utilized to maximize placement of the prosthetic platform of these implants. Osseous resorption and enlargement of the maxillary sinus can complicate treatment of edentulous areas of the posterior maxilla. Treating such cases with traditional dental implants can be challenging, and treatment time, morbidity, and costs may significantly increase for the patient. Treatment planning options for the management of these types of severely resorbed partially or completely edentulous maxillae have been expanded to include the use of the zygomatic process for immediate implant fixation and stabilization with immediate function. This approach averts the need for significant grafting to enable implant placement in the posterior maxilla and allows implants to be placed into denser, more stable bone.
Anchored in the upper jaw bone, close to the cheek bone, zygomatic implants are an effective option for patients who do not have adequate bone mass in their upper jaw for traditional dental implants. Zygomatic implants avoid complex sinus lift and bone grafting procedures, and therefore offer shorter, more comfortable recovery times. This graft-less procedure has a long track record of success and offers an immediate prosthetic solution for patients with severe bone atrophy in the upper jaw. Temporary restorations can be fixed immediately, giving patients an instant aesthetic and functional improvement. After the implants have fused with the bone and healing is completed, custom-fabricated restorations will be placed. This advanced technique significantly reduces the timeline for receiving replacement teeth, allowing patients to enjoy restored function, better aesthetics and increased confidence about their smile. This minimally-invasive procedure uses 3D scanning for maximum accuracy and is usually performed under IV sedation. Unlike bone grafting treatments that can take 12 months to heal, zygomatic implants can be completed in one stage, giving patients “Teeth in a Day.” Zygomatic implants may be recommended in cases involving failed dental implants, failed bone grafting operations and extreme jaw bone deterioration.
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.
