Introduction: Anterior open bite is one of the most challenging malocclusion to treat non-surgically in orthodontics and dentofacial orthopedics. By zygomatic bone-anchored orthodontic plates, significant molar intrusion can be done, which represents a real alternative to orthognathic surgery. Ojectives: To assess the effectiveness of skeletal anchorage for anterior open bite treatment in an adult patient and to evaluate the esthetic and functional outcomes. Methods: This case report reveals the orthodontic treatment of a 26-year-old female patient. Zygomatic anchorage for the intrusion of the maxillary posterior teeth was used and the dental and skeletal relationships was corrected. Results: At the end of the treatment, the reduction of the dentoalveolar height achieved by the intrusion of the maxillary molar zone treated the anterior open bite, and the counter-clockwise rotation of the mandible improved the skeletal discrepancy. Improvements in dental and facial esthetics were also observed. Conclusions: The present case report supports that skeletal anchorage using zygomatic plates is an effective method for open-bite treatment based on molar intrusion, where a more significant amount of vertical tooth movement is necessary to compensate for the absence of growth changes. Complete diagnosis and appropriate treatment planning are essential to have the required result, both from an occlusal and aesthetic point of view.
