Abstract: A method for generating and fabricating a dental device having a body. The body may have a first plurality of tooth receiving cavities shaped to receive teeth of a first side of an arch. The body may also have a second plurality of tooth receiving cavities shaped to receive teeth of a second side of an arch. A palatal portion may extend between the first plurality of tooth receiving cavities and the second plurality of tooth receiving cavities. The palatal portion may be shaped to apply an expansion force to the teeth of the first side of the arch and the teeth of the second side of the arch. The palatal portion may include a plurality of bands that extend between the first plurality of tooth receiving cavities and the second plurality of tooth receiving cavities, each respective band may have a respective different thickness.
