The Nord Crossbite is perfect for patients with a crossbite and whose median lines are deviated. This design is a unilateral palatal expansion appliance with two screws that must be activated at the rate of 0.025 mm twice a week. With a crossbite, the pad must be smooth to avoid interference with antagonistic teeth.
Material required for manufacturing
– Upper stone model
– Lower stone model
– Articulated wax with 2 mm space between the molars
Patients may choose the colour of their appliances. Regular acrylic is then replaced with coloured acrylic. One to three colours may also be chosen per appliance. These options actually encourage children to cooperate closely during orthodontic treatment
