Pivoting appliance
定義：A hard acrylic device that covers one arch and usually provides a single posterior contact in each quadrant.
作用：This was thought to be possible when the anterior teeth moved closer together, creating a fulcrum around the second molar, pivoting the condyle downward and backward away from the fossa.
