Bionators are used to __ the bite.

• A. Open
• B. Open or Close
• C. Close
• D. Stabilize

Answer: (B)

Bionators are functional appliances that influence how the jaws and muscles function, which in turn changes the way the teeth meet. By guiding the mandible into a forward position and altering incisal and posterior contacts, they can modify the vertical dimension of the bite. Because of this, they can be used to either increase or decrease how the teeth come together, depending on the treatment goal and how the appliance is used. That makes “open or close” the most accurate description of what they can achieve. In practice, if the goal is to open the bite (increase vertical dimension) for a patient with a deep bite, the appliance can permit or encourage posterior eruption and a forward mandibular posture that elevates the bite. If the aim is to promote bite closure or improve contact, adjustments and wearing can help bring the teeth into better occlusion.
