Bionator I

The Bionator I is used for the correction of Class II malocclusions with a deep bite. It can serve to stimulate alveolar growth for patients with a deep overbite while gaining space and correcting an open bite in mixed dentition cases. The design incorporates fluted grooves in the posterior section along with an anterior bite plate to allow posterior eruption allowing lower facial height. We place an anterior cap for stability as the lower advances into position with the upper.



Treatment & Care

Ideally, treatment starts should range from 8-11 years old, and recommended wear time is 21-23 hours a day. Treatment results in a change in overjet of one mm per month. You can add an optional expansion screw to stimulate the growth of the posterior teeth.

Patients should clean daily with toothpaste to prevent the buildup of plaque and odor.  Avoid Efferdent and other effervescent solutions, as it may erode components on the appliance. It is recommended to use products like DentaSoak or Retainer Splash.
