Abstract
Open bite has fascinated Orthodontics due to the difficulties regarding its treatment and maintenance of results. This anomaly has distinct characteristics that, in addition to the complexity of multiple etiological factors, have aesthetic and functional consequences. Within this etiological context, several types of mechanics have been used in open bite treatment, such as palatal crib, orthopedic forces, occlusal adjustment, orthodontic camouflage with or without extraction, orthodontic intervention using mini-implants or mini-plates, and even orthognathic surgery. An accurate diagnosis and etiological determination are always the best guides to establish the objectives and the ideal treatment plan for such a malocclusion. This report describes two cases of open bite. At the end of the treatment, both patients had their canines and molars in Class I occlusion, normal overjet and overbite, and stability during the posttreatment period.
Highlights
Open bite is an anomaly with distinct characteristics that are recognized, present in 25% to 38% of the orthodontically treated patients [1]
Various mechanical alternatives are available in the literature: palatal crib [2], orthodontic camouflage with premolars or first molars extraction [3], magnets [4], mini-implants [5], mini-plates [6] and orthognathic surgery [7]
This report describes the procedures relative to diagnosis, orthodontic treatment planning and stability based on a 2-year treatment of two cases of open bite
