[Mioconverter].

Mioconverter is a new appliance created by author used in the treatment of open bite. It is consisted of two free plates connected by added joint (similar to connection in the TMJ) Plates have lateral bite blocks, anchorage elements in the frontal region and a joint at the back. Joints are originally created by the author as an imitation of TMJ and mandibular ramus. The appliance converts muscle strength in the way of extruding frontal teeth, intruding molars, and rotating the upper and lower jaw. Finally, mioconverter reduces vertical skeletal discrepancy. The leaning plate is under the occlusal level. Therefore, mioconverter utilizes all types of forces used in the lower jaw movements. Results of treatment of a case with an open bite are illustrated.
