Which term denotes the vertical dimension at rest?

• A. Vertical Dimension at Rest (VDR)
• B. Vertical Dimension of Occlusion (VDO)
• C. Interocclusal distance
• D. Resting height

Answer: (A)

In restorative and occlusal dentistry, the key idea is the difference between how the jaws sit at rest versus when the teeth occlude. Vertical Dimension at Rest is the distance between two reference points when the mandible is in physiologic rest with muscles relaxed. This position leaves a small gap between the teeth called the freeway space, typically about 2–4 mm, which is the interocclusal distance. Vertical Dimension of Occlusion, on the other hand, is the distance between those points when the teeth are in contact in occlusion. The interocclusal distance simply reflects the gap between rest and occlusion—the difference between VDR and VDO. Resting height isn’t a standard term for this concept. So, the term that denotes the vertical dimension at rest is Vertical Dimension at Rest.
