Immediate Loading in Atrophic Jaws: Zygomatic Implants

The zygomatic fixture is an extended length (35–55 mm) titanium implant, placed into the zygomatic and maxillary alveolar bone. It was designed for situations where atrophy of the posterior maxilla complicates or prevents the placing of conventional implants. The use of zygomatic implants avoids the need for bone grafting, shortens treatment times, and reduces morbidity. They have also been used in patients with maxillectomies resulting from tumors or diseases associated with atrophic conditions of the maxilla.
