What are the typical uses of an articulator in dental practice?

• A. Diagnose occlusion
• B. Plan dental procedures
• C. Aid in fabrication of restorations
• D. All of the above

Answer: (D)

Articulators provide a controlled, repeatable representation of the jaw joints and bite, letting clinicians study how teeth come together during closure and movement without the patient present. This makes it possible to diagnose occlusion by observing static contacts, guidance, and interferences in different jaw movements. It also aids in planning dental procedures by modeling how restorations, tooth wear corrections, or orthodontic changes will affect the bite, adjusting vertical dimension, and selecting occlusal schemes. In the fabrication of restorations, mounting casts on the articulator allows the lab to craft crowns, bridges, or full-arch prostheses with correct occlusal contacts, cusp angles, and incisal guidance, and to transfer those relationships to the mouth accurately. All of these uses are common, though the accuracy depends on proper mounting and records to avoid misleading occlusal relationships.
