Introducing the bite-plate effect (fig. 6.9) in deep-bite cases is helpful in the bite-opening process in three ways:
1. It allows for early placement of brackets on lower incisors, which begins their movement.
2. Anterior bite plates can produce an intrusive force on lower incisors which limits any future extrusion of these teeth.
3. Anterior bite plates allow for the eruption, extrusion, and/or uprighting of posterior teeth.
