There are several different types of orthodontic appliances used to correct a Class II malocclusion. The Forsus and the PowerScope are a couple of those appliances.
The Forsus appliance is a fixed appliance that is attached to the upper and lower teeth. It works by pushing the top teeth back and the bottom teeth forward and replaces the need for headgear or elastics Depending on the severity of the bite, you can expect to wear the Forsus appliance for about 6 to 9 months.
Like the Forsus appliance, the PowerScope appliance is a fixed appliance that delivers continuous forces to help efficiently and effectively align your bite. Unlike headgear or elastics, PowerScope doesn’t need to be removed or adjusted, and the small, smooth appliance is barely noticeable.
