Orthodontics, Maxillofacial Surgery, and Asymmetries: Skeletal Anchorage for the Correction of the Canted Occlusal Plane

The use of temporary anchorage devices (TADs) as a possible alternative in doing orthodontic treatment without or limited surgical intervention in problems involved the canted occlusal plane. With all treatments of asymmetries with a canted occlusal plane primarily involved, the practice of myofunctional therapy is recommended to be part of the overall treatment plan. The use of TADs provides a semi-fixed anchorage that can be placed in strategic locations that might be difficult or impossible in the past, resulting in a predictable and reliable way of bone-borne anchorage. The Trans-Palatal Arc (TPA) plus hooks is one of the few devices intended to control en-masse the entire dentition within the dental arch in the three-dimensional space and correct the canted occlusal plane. The TPA plus hooks system is intended to assist in correcting the canted occlusal plane which is dominated by Roll and Pitch motions, respectively.
