Bionators


Bionator: No Midline Screw


The Bionator utilizes acrylic flanges on the upper and lower lingual tissue to protrude the mandible into the proper position. The acrylic can be trimmed inter-occlusally to all the vertical position of the posterior teeth to be controlled. Therefore the appliance can be trimmed to open, close or maintian the bite. Expansion screws can also be added to aid in arch development. Bionators are currently used for class II correction as well as retention for Herbst treatment.
