Bionator Appliance

The Bionator I (to open bite) is designed to aid in correction of Class II malocclusions by maintaining the mandible in an advanced position and guiding eruption of the posterior teeth. In order to prevent the super eruption of the anterior teeth, the mandibular anteriors are covered with an acrylic cap which comes in contact with the maxillary anteriors. An expansion screw can be added to maintain a tight fit of the appliance.

The Bionator II (to close bite)is designed to aid in correction of Class II malocclusions and the reduction of an anterior open bite. The latter is achieved by keeping the acrylic coverage over the occlusal surfaces of the posterior teeth. An expansion screw can be added to maintain a tight fit of the appliance.
