Abstract
|
|
|
The Horseshoe appliance was introduced by Dr. Schwarz, and it is used to correct sagittal relationships by elastic force in class Ⅲmalocclusion.It minimizes the increment of lower anterior facial height and allows the mandible to be repositioned harmoniously with the soft tissue and muscle matrix of the jaw. It has the advantages of better patient cooperation, easier construction, and more effective modification.
In the patients who were treated with Horseshoe appliance, forward growth of maxilla and counterclockwise rotation of occlusal plane with labioversion of maxillary incisors and linguoversion of mandibular incisors were obtained Minimum downward and backward rotation of mandible was accepted, so increasing of lower anterior facial height was minimized.
