Maxillary schwartz

This appliance is intended to create space in a crowded dentition in order to allow more room to align the teeth. This is accomplished by utilizing a screw imbedded in the acrylic plate, which is opened in small increments over a prescribed treatment period using a wire key. As the screw is opened, a split in the acrylic plate widens along the midline causing it to apply pressure laterally against the teeth. This pressure gradually widens the patient’s arch creating additional space in which to align the teeth.
