An impression used to record the bite relationship is called what?

• A. Occlusal
• B. Preliminary
• C. Final
• D. Diagnostic

Answer: (A)

The main idea here is capturing how the upper and lower teeth come together, which is about occlusion. An impression made specifically to record that bite relationship is an occlusal impression, or bite registration, because it documents how the teeth contact each other and the jaw position. This record lets the dentist mount the casts in an articulator with the correct vertical dimension and alignment for fabricating dentures or restorations. The other terms describe different purposes or stages of impression-taking rather than the bite itself: preliminary impressions are initial forms for study casts, final impressions are the detailed forms for fabrication, and diagnostic impressions are for evaluation and planning. So the correct term is occlusal.
