Where are Zygomatic Implants specifically anchored due to extreme upper jaw bone resorption?
Answer
Dense cheekbone (zygoma)
Zygomatic implants are a highly specialized anchoring solution reserved for cases involving extreme bone loss in the maxilla where traditional jawbone grafting is unfeasible or rejected by the patient. Instead of being placed in the jawbone itself, these significantly longer posts are secured into the dense, robust bone of the zygoma, commonly known as the cheekbone. This strategic placement bypasses the areas of severe resorption in the jaw ridge, allowing for the secure placement of full arch restorations, often utilizing protocols like All-on-4. This technique demands a high degree of surgical expertise due to the proximity to critical anatomical structures like the maxillary sinuses.
