Aim: Open bites are challenging malocclusions with a multifactorial etiology, varying clinical severity, and questionable stability. The aim of this article is to describe a method for maximizing tissue response in the treatment of selected subjects with anterior open bites. Method: Twelve subjects with an anterior open bite and insufficient incisor display underwent a limited corticotomy to augment alveolar bone response by creating an anteroposterior intra-arch anchorage differential. Cephalometric radiographs were taken before treatment (T1) and 1 month after open bite closure (T2). The change in perceived smile esthetics was assessed by a visual analog scale. Results: All open bites were closed after a mean of 6 weeks. Radiographic evaluation showed significant maxillary incisor extrusion and retrusion. There was a notable improvement in smile esthetics after treatment. Conclusion: It is possible to close anterior open bites rapidly with significant improvement in smile esthetics in a selected group of anterior open-bite subjects. World J Orthod 2009;10:187–195.
