Appliances are divided into two classes, fixed and removable. It is through the work of V. H. Jackson that removable appliances have been developed to their present use fulness. It may be said that it is possible to treat any type of malocclusion with removable appliances, although a number of varieties of malocclusions can be more successfully and more easily treated with this form.
