Abstract

Recently, the population of orthodontic treatment for adult is increasing at a great rate. And, orthodontic treatment of open bite malocclusion has been considered a very difficult problem, especially in adults. Because of the strong relapse tendency in vertical control of posterior teeth, many treatment trials have been proposed. But, many treatment plans have side effects like anterior teeth extrusion or deterioration of facial profile. Therefore, the vertical control of posterior teeth is very important key of treatment in adult open bite malocclusion. Without intermaxillary elastics or surgery, a good result of orthodontic treatment could be provided with simple maxillary and mandibular micro-implant anchorage.
