Bionators allow for __ posturing of the mandible.

Explanation:
Forward posturing of the mandible is the effect aimed for with a bionator. This functional appliance is designed to hold the lower jaw forward during both function and rest, which helps guide the mandible to grow in a forward direction in growing patients. By maintaining this anterior position, it stimulates adaptive remodeling of the mandible and condylar growth, improving the sagittal jaw relationship (reducing overjet and helping Class II correction). Lateral or vertical posturing isn’t the goal, and backward posturing would defeat the purpose by keeping the jaw retruded or altering dimensions in the wrong way.
