The bionator Balters type II is used for which malocclusion?

• A. Malocclusion Class II/1 by Angle
• B. Crossed bite
• C. Open bite
• D. Deep bite

Answer: (C)

Functional appliances work by guiding muscle function to change jaw position and eruption patterns during growth. The Balters Bionator type II is specifically designed to address open bites. It positions the lower jaw forward and provides guidance for the bite to close, which helps establish anterior contact and reduces the vertical separation seen in open bite cases. It also helps retrain tongue posture and stop tongue-thrust habits that commonly accompany open bite, supporting closure over time. It isn’t aimed at correcting a crossbite, which would require expansion or different guidance of the jaw; nor is it primarily used for a deep bite, where the goal is often intrusion of the anterior teeth or other vertical-control mechanics; nor is it the first choice for a Class II division 1 pattern, which is typically treated with appliances focused on advancing the mandible or retraining dental relationships rather than specifically closing an open bite.
