Open bite is an indication for which appliance?

• A. Bionator Balters type II
• B. Frenkel type III
• C. Andresen-Haupl activator
• D. Functional regulator Type I

Answer: (A)

Open bite often stems from a combination of vertical growth patterns and dysfunctional tongue or facial muscle habits. The goal with a functional appliance in this situation is to re-educate the neuromuscular system and guide jaw position so that the bite can close more normally. The Bionator Balters type II is designed to encourage a forward, functional mandibular position while promoting proper tongue posture and lip seal. This combination helps reduce tongue-thrust tendencies and normalize muscle function, which in turn aids in closing the anterior open bite and achieving a stable occlusion. Its design makes it particularly suited for open bite cases where modifying both jaw position and soft-tissue function is advantageous, more so than appliances that focus primarily on pure muscle training or on other Class II mechanics.
