title: Maximizing tissue response in selected subjects with anterior open bites.
abstract: OBJECTIVE
  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.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  It is possible to close anterior open bites rapidly with significant improvement in smile esthetics in a selected group of anterior open-bite subjects.
