Abstract:
The aim of the present study was to evaluate the effects of the miniscrew-supported, modified Hyrax appliance on bilateral distalization of posterior teeth. A 15-year-old girl with Class II malocclusion (end-to-end molar relationships, space deficiency for maxillary canine) underwent orthodontic treatment. The patient rejected tooth extraction. Then, she was treated with the miniscrew-supported, modified Hyrax appliance. An activation of 1 mm per month was planned. Lateral cephalometric views were used to evaluate distal movement. Distalization was successfully achieved at 4 months. No anchorage loss and incisor protrusion were noted. It would be beneficial to choose this appliance for the distalization of maxillary molars in patients with maxillary incisor protrusion, as this appliance does not cause anchorage loss in the upper jaw.

Self-Locking Screw
A square-threaded screw jack carrying a load is considered self-locking if the screw retains its position even after the moment applied to it is removed.
Frictional Forces on Screws
A jack with a square-threaded screw is a mechanical device used to lift heavy loads by applying a force at its handle. When the force is applied, the screw turns, raising the load. The screw can...
