CASE REPORT
Nonsurgical Treatment of a Severe Skeletal Anterior Open Bite
Volume 51 : Number 2 : Page 0 : Feb 2017
The etiology of anterior open bite is generally multifactorial, involving a combination of skeletal, dental, and functional effects. Potential causes have been listed as unfavorable growth patterns, digit-sucking habits, enlarged lymphatic tissue, heredity, and oral functional matrices. The most common characteristics of anterior open bite are incisor protrusion and overeruption, but other features may include excessive gonial, mandibular, and occlusal plane angles; a short mandibular body and ramus; excessive lower anterior facial height; reduced lower posterior facial height and upper anterior facial height; a retrusive mandible; a Class II tendency; divergent cephalometric planes; a steep anterior cranial base; and inadequate lip seal. Some studies have found a correlation between a weak orofacial musculature and a long face and consequent anterior open bite.
