Twin Block

The twin block is two appliances one upper and one lower that work together as one. The upper includes an optional expansion screw to widen the upper arch as needed as well as pads to cover the molars. The lower plate includes pads to cover the lower bicuspids. The two appliances interlock at an angle and move the lower jaw forward and lock it into the ideal position when the patient bites together. This new position in time will become the permanent corrected position.
