Abstract
This study aimed to investigate dentofacial changes in patients treated with maxillary molar intrusion with zygomatic anchors. The study group was composed of 19 patients with anterior open bite who had intrusion of the posterior dentoalveolar segment using an acrylic appliance supported by bilateral zygomatic miniplates. The study was carried out on lateral cephalograms of the subjects taken before treatment and after intrusion. Cephalometric changes obtained with maxillary molar intrusion were statistically significant. ANB, Wits, SN-GoGn, PP-MP, ANS-Me, NA-APo, SN-OP, U1-OP, U6-NF, overjet, and overbite values were also statistically significant. Posterior dentoalveolar intrusion by zygomatic anchorage was an effective method for anterior open bite treatment. Although overbite and vertical skeletal measurementschanged because of posterior dentoalveolar intrusion, the soft tissue was not significantly affected.
