An articulator described as average-value with a fixed condylar path set at 30 degrees is classified as which class?

• A. Class 1 Articulators
• B. Class 2 Articulators
• C. Class 3 Articulators
• D. Class 4 Articulators

Answer: (B)

Articulator class reflects how much its settings mimic a patient’s jaw movements. An average-value articulator uses a standard, fixed condylar inclination rather than patient-specific measurements. A condylar path set at 30 degrees shows it’s using a typical average value, not a personalized angle. That’s exactly what defines an average-value articulator: it provides a generic representation for mounting casts and assessing occlusion, without tailoring to the individual’s condylar guidance. In contrast, a non-adjustable hinge would have no usable condylar guidance, and a fully adjustable articulator would allow altering the condylar angle to match the patient’s actual anatomy.
