Bionator blocks provide __ control.

Bionator blocks provide __ control.

• A. Horizontal
• B. Lateral
• C. Vertical
• D. Rotational

Answer: (C)

Bionator blocks are bite blocks that sit between the upper and lower teeth to create a vertical stop. This vertical separation controls how much the posterior teeth can erupt and how the dentition interact during growth, which in turn helps regulate the vertical dimension of the bite as the mandible is gently guided forward. In other words, these blocks are primarily about managing vertical relationships rather than moving the jaw forward in a horizontal sense, changing the sideways (lateral) relation, or producing rotational changes. That’s why vertical control is the best description of their function.
