What is the primary purpose of an occlusal analysis using articulating paper?

• A. To identify high spots and premature contacts that cause interferences and abnormal muscle activity.
• B. To measure vertical dimension of occlusion.
• C. To assess tooth shade and color.
• D. To evaluate periodontal probing depths.

Answer: (B)

Articulating paper in occlusal analysis is used to reveal where teeth contact as the jaws come together. The main purpose is to identify high spots and premature contacts that create occlusal interferences and can trigger abnormal muscle activity. When these contacts are present, the bite can cause uneven force distribution, leading to muscle fatigue, tension, or grinding patterns as the muscles try to accommodate. Detecting and adjusting these contacts helps stabilize the bite and reduce excessive muscle activity and wear.

Measuring vertical dimension of occlusion isn’t accomplished with articulating paper itself; it requires other methods and records to assess how tall the bite is in relation to the skull. Likewise, tooth shade and color are esthetic considerations, and periodontal probing depths relate to gum health rather than the occlusal contacts.
