Which tongue resting position is not a risk factor for vertical inocclusion?

• A. The retracted
• B. The protracted
• C. Between the arches
• D. Retroincisive

Answer: (D)

Resting tongue posture influences vertical occlusion because the pressures the tongue applies at rest can alter the height of the bite and how the teeth relate top-to-bottom. When the tongue sits between the arches or moves forward toward the teeth, it tends to push or separate the teeth in a way that can increase vertical dimension and promote an open bite tendency. In contrast, the retroincisive position—the tongue resting against the palate with the tip just behind the upper incisors—aligns with a normal, stable rest and does not impart those disruptive forces on the incisors or the arches. So, this posterior, palate-backed position is not a risk factor for vertical occlusal issues.
