When an Orthodontist talks about the need for Distalization, they mean that teeth need to be pulled backward, away from the midline. For example, they might decide that you need molar distalization, where your molars are pulled backwards in the arch. Molar distalization is often used as part of the treatment for patients who have Class II Maloclussion. Sometimes molars are distalized to make space for other impacted teeth, such as premolars or canines, in the mouth. Because of the anatomy of your jaws, it is easier to distalize the upper jaw (maxillary arch) than the lower jaw (mandibular arch). Two appliances commonly used for molar distalization are the Pendulum Appliance and the Pendex Appliance. The above photo shows an example of a Pendulum Appliance made by DynaFlex.
