Open bite correction by intrusion of posterior teeth with miniscrews.
The application of orthodontic miniscrews has simplified the treatment of an anterior open bite by making it more efficient and esthetic. A 19-year-old woman with an anterior open bite was treated by an intrusion of the maxillary posterior teeth using miniscrews. The posterior teeth were splinted on the palatal side with rapid maxillary expansion (RME), and an intrusive force was then applied to the miniscrews on the buccal side. The 3.5 mm anterior open bite was corrected after 5 months of intrusion. As a result, a harmonious facial profile was achieved by a closing mandibular rotation.
