Open Bite

An open bite is considered to be one of the most difficult dentofacial deformities to treat in Orthodontics.The complexity of this malocclusion is attributed to combination of dentoalveolar, skeletal, functional and habit related factors. It is characterized by large anterior dentoalveolar height in both jaws, increased total and lower anterior face height, a disproportionate ratio of upper to lower anterior face height, decreased posterior face height, an increased gonial angle, a high mandibular plane angle, a low posterior to anterior face height ratio and a short ramus.
