Abstract Anterior open bite is often characterized by excessive vertical development of the posterior maxilla and by excessive eruption of the posterior teeth. Intrusion of the over-erupted molar teeth by traditional orthodontic methods is hardly possible; it requires orthognathic surgery or an absolute skeletal anchorage. These three case reports demonstrate the impaction of the upper molars by using zygomatic miniplates and fixed orthodontic treatment. After treatment, in all cases, the upper molar intrusions and significant correction of open bite were achieved by using zygomatic anchorage, and reduction of vertical dimensions enhanced facial aesthetics.
