Which statement best describes Hand Articulated articulation in denture fabrication?

• A. The arches' relationship is reproduced exactly without bite registration
• B. The arches are articulated using bite registration
• C. The arches are aligned using a fully adjustable articulator
• D. The models are joined with a static base

Answer: (A)

Hand articulation focuses on recreating how the upper and lower arches relate to each other without using a bite-registration record. The technician manually positions the casts on the articulator, guided by anatomical cues, wax rims, and the dentist’s instructions, to mirror the patient’s occlusion without relying on a bite registration. This approach emphasizes the hands-on control of the occlusal relationship rather than recording it with bite material. It differs from using a bite registration (which fixes the relation with a recorded bite), from relying on a fully adjustable articulator (which uses mechanical settings for movement), or from simply mounting the models on a static base (which doesn’t actively establish occlusion). So, reproducing the arches’ relationship without bite registration is the best description of hand articulation.
