In open bite cases, a comprehensive diagnostic differentiation is crucial in determining the best corrective therapy. In non-surgical open bite treatment, fixed appliances, either labial or lingual, are usually employed. With the addition of extra-radicular screws, more sophisticated orthodontic movements may now be performed without the necessity for orthognathic surgery. Clear aligner therapy, on the contrary, has grown in popularity as a treatment option for more complex cases, such as open bite malocclusions. This article discusses three cases with an anterior open bite that were treated using various mechanics as dictated by the malocclusion. Case 1 was addressed wholly using clear aligner therapy, with careful consideration of attachment geometry and mechanics. Case 2 with clear aligner therapy, attachment geometry selection, and vertical elastics; and Case 3 with clear aligner therapy, attachments, and temporary anchorage devices.
