The Anterior Bite Plate is used to treat a deep bite. Working on the principle that an unopposed tooth will continue to erupt until it comes into contact with another surface, this appliance holds the anteriors while allowing the posteriors to erupt. An acrylic shelf is built into a Maxillary Plate in the anterior region where it will be contacted by the Mandibular anteriors holding the bite open in the posterior region. This will cause the posterior teeth to erupt and open a deep bite.
