Sagittals employed to distalize upper first molars are primarily used to treat Skeletal Class I Dental Class 2 cases and Skeletal Class II Dental Class 2 cases. Adequate anchorage is the key to successfully moving molars. The anterior teeth, along with the palatal acrylic, labial bow and Adams Clasps comprise this anchorage unit. When it is possible, the anchorage unit should even include the bicuspids. Doing so will make it unnecessary to cover the occlusal surfaces with acrylic. WARNING: Distalizing molars can cause the patient’s bite to open. This is great for skeletal deep bite cases but often very difficult to manage in open bite scenarios. Note: Distal movement of the molars is much easier when the second molars have been removed or when they have not yet erupted. When second molars are not yet erupted, it is important to check their position to be certain that first molar distalization will not create an impaction. This can easily be accomplished by taking an x-ray of the second molars. In some cases, removal of the second molars may be indicated.
