Is an upper and lower occlusal splint that has a fixed vertical opening and the lower jaw is held forward by a fixed upper piece which pushes the fins forward. This push type device does not work well for patients who want to move their jaw laterally or left to right.

Is a thinner plastic device that fits directly over the upper and lower teeth and is designed to advance the jaw and open the bite vertically. Advancement is accomplished by placing the plastic bands on each side of the device. This device allows comfort and ease of movement in lateral positions.
