Digital W Arch Appliance (Orthodontic Appliance)

The W Arch or Porter appliance is fabricated using .036 wire. The appliance is activated by opening the apices and can be easily adjusted to provide more anterior or posterior expansion. The appliance should be manually opened 3-4 mm before insertion to provide proper forces. The expansion should continue at a rate of 2mm per month until the crossbite is overcorrected.
