After a Class II has been corrected, the Removable Rick-A-Nator 2 is commonly used as a support phase appliance during fixed mechanics -- when you plan to use posterior forced eruption mechanics to settle-in the occlusion. One of the benefits appliance is that it can be removed for social functions -- although it obviously needs to be worn as much as possible...especially during the application of vertical mechanics. This appliance provides the same condylar support function as the Fixed Rick-A-Nator 2. Note: Because it is removable, this design is not recommended for TMD patients who need continual condylar support.
