This is a removable functional appliance used to help with correction of Class 2 malocclusions and deep bites. The appliance joins to the upper and lower arches in a protruded position with no acrylic coverage over the posterior teeth. The posterior acrylic is cut into "channels" allowing for the correction of the deep bite. The clear acrylic cap over the lower anterior teeth prevents any undesirable eruption. A heavy gauge coffin loop holds the posterior segments of the appliance together allowing proper position of the tongue and allowing for a small amount of activation for lateral expansion.
