Abstract

Objective: The aim of this study is to investigate the effectiveness of the mini-plate zygomatic anchorage for intrusion of maxillary molars in adult skeletal anterior open-bite patients. Materials and Methods: The study group was composed of 10 anterior open-bite patients with posterior dentoalveolar excess. Placement of the mini-plates in the zygomatic buttress was carried out under local anaesthesia. After placement of a double TPA, a closed Ni-Ti coil spring was placed bilaterally between the hook of the mini-plate just mesial and distal to the first molar buccal tube applying intrusive force of 450g per side. Lateral cephalograms and posteroanterior radiographs were taken before intrusion (T1: post upper segmental leveling) and after intrusion (T2). The cephalometric films were measured and compared. Results: The mean amount of accomplished molar intrusion was 3.1mm ± 0.74mm, with a rate of 0.36mm per month ± 0.08mm per month and a bite closure of 6.55mm±1.83mm. Mandibular autorotation followed the molar intrusion, SNB and SN-Pog angles significantly increased while the ANB, MP-SN angle and N-S-Gn angle significantly decreased. There was no significant buccal tip in the right and left molars. Conclusion: Zygomatic anchorage can be used effectively for skeletal open-bite correction through posterior dento-alveolar intrusion.
