Nitanium Palatal Expander

The nitanium palatal expander is a fixed/removable nickel titanium appliance. The expander incorporates a lingual attachment that fits into a horizontal lingual sheath welded to the maxillary molar bands. The appliance exerts a continuous low force on the maxillary teeth and midpalatal suture. This is provided by harnessing the wire’s shape memory at body temperature.
