Transpalatal Arch Appliance

A Transpalatal Arch (TPA) is a fixed orthodontics appliance that is used to maintain the arch width between the first molars and to de-rotate rotated molars. A wire is soldered to the first molars and runs laterally across the palate preventing a lingual drift. An adjustment loop is located in the middle of the wire and is activated as needed to de-rotate the first molars. Learn about our other ortho appliances as well.
