Noncompliance open-bite treatment with Zygomatic anchorage

Objective: To evaluate the dentoalveolar and skeletal effects of the new-generation open-bite appliance. Subjects and Methods: The study group was composed of 11 subjects with a mean age of 19.5 years who underwent intrusion of the posterior dentoalveolar segment using an open-bite appliance supported by bilateral zygomatic implants. The study was carried out on lateral cephalograms of the subjects taken before treatment and after intrusion. The mean intrusion time was 9.6 months. Results: The mean intrusion measured as the distance of the U6 to the palatal plane was 3.6 +/- 1.4 mm (P .05), except for the interincisal angle, which was increased by 3.5 degrees (P < .05). Conclusion: Zygomatic anchorage can be used effectively for open-bite correction through posterior dentoalveolar intrusion
