Correction of anterior open bite of varying severity using clear aligner therapy—A case series

Abstract

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.

Management of a severe skeletal open bite case using temporary anchorage devices and multiloop edgewise arch wire technique

“…In this case a major profile change could be achieved for the patient with improved aesthetics because of the correction of the severe open bite. A combination of miniscrews and MEAW wire was used to re‐orient the occlusal plane, which could substantially change the patient's profile 11–14 . Many contemporary techniques can help orthodontic practitioners achieve a much‐improved patient treatment outcome 15,16 …”

“…The MEAW technique is complemented with the use of inter-maxillary elastics, occlusal plane, which substantially change the patient's profile. [11][12][13][14] Many contemporary techniques can help orthodontic practitioners achieve a much-improved patient treatment outcome. 15,16…”

Stability and Success of Clear Aligners in Orthodontics: A Narrative Review

“…Sabouni et al studied the implication of clear aligners in the treatment of open bite, incorporating three cases: clear aligners alone, clear aligners with attachments and vertical elastics, and clear aligners with attachments and temporary anchorage devices [17]. The research showed satisfactory success in all three scenarios, with auxiliaries treating more complex cases.…”

“…It emphasized that these types of malocclusions responded better to treatment with clear aligners than fixed appliance therapy because they apply less extrusive force on posterior teeth, which are meant to be intruded in the treatment of open bite. The treatment of open bite with clear aligners involves the combined intrusion of maxillary and mandibular teeth and the combined extrusion of maxillary and mandibular anterior teeth [17].…”
