Figure 2: The Transverse Palatal Expander. TransForce® lingual appliances can be used for first phase arch development or integrated with fixed appliances. (a) Severe crowding of the upper incisors in this 8-year-old girl is treated with invisible TransForce Appliances® to expand arch width.Treatment was completed in 8 months followed by 3 months retention. The teeth remain straight after a period of observation when reviewed 2 years later waiting for the permanent canines to erupt. (b) Three years later fixed appliances are fitted for a few months to complete treatment. Early treatment is often followed by a second stage of treatment. This approach may avoid extractions and Train Tracks are worn for a shorter time if crowding is corrected at an earlier stage
