Bionators prevent the teeth from __.

Explanation:
Bionators have a bite-block effect that helps control vertical eruption during growth modification. The design provides posterior occlusal stops, which prevents those teeth from moving downward and erupting further as the jaw is guided forward. This vertical control is part of how the appliance stabilizes the bite while encouraging mandible advancement. So, the action described is preventing extrusion of the teeth.
