About

This study will aim to evaluate the effect of skeletally anchored extrusion arch on the dentofacial structures in patients with anterior open bite (AOB).

Full description

This study will be a prospective clinical study. All the patients will be treated with 0.022 inch slot Roth metal brackets. Orthodontic bands will be cemented to the maxillary first molars. Both maxillary and mandibular teeth, will be sectionally leveled and aligned with superelastic Ni-Ti archwires.

A buccal stiff sectional wire from the first molar to the canine will be added for anchorage reinforcement. Extrusion will be done by inverting a 0.017 × 0.025-inch Connecticut intrusion archwire and inserting it in the molar auxiliary tubes upside-down and miniscrew will be tied to the molar bands to act as additional indirect anchorage.
