Application and Implementation of Orthodontic Devices Used in Upper Jaw Narrowing

In the application of improved orthodontic devices in the treatment of pathological occlusions caused by narrowing of the upper jaw, there is a plastic base, an occlusion surface in the area of chewing teeth, a three-way extension screw and lip pilots, a U-shaped loop connecting with the base part of the pilot. Connecting loops with a face mask attached to the base face mask rely on the chin as well as the forehead area, causing the middle part of the face to come forward, the growth of the upper jaw in the sagital direction.
