Which term describes contact between the maxillary and mandibular posterior teeth on the same side as the direction the mandible has moved?

Which term describes contact between the maxillary and mandibular posterior teeth on the same side as the direction the mandible has moved?

• A. Working Side
• B. Non-working Side
• C. Centric Contacts
• D. Mandibular Movements

Answer: (A)

When the jaw shifts to one side, the teeth on that same side come into contact—these posterior contacts on the moving side are called the working side. This side is where the mandible moves toward, and the occlusal contacts help guide and stabilize that movement. The opposite side is the non-working (or balancing) side, where contacts are minimized to avoid interference. Centric contacts refer to static contacts in a jaw at a specific relation, not to movement direction, and mandibular movements is a broad term for jaw motion. So the described contacts fit the working side.
