Disclusion on non-working side refers to the separation of posterior teeth on the side where the mandible moves toward the:

• A. Non-working side
• B. Working side
• C. Centric relation
• D. Maximal intercuspal position

Answer: (A)

Disclusion on the non-working side happens during lateral jaw movement. When the mandible shifts to the working side, the posterior teeth on the opposite side (the non-working side) disengage and separate. This separation protects the teeth and joints from lateral interferences and is usually guided by anterior guidance (or canine guidance) so that only the working-side teeth may contact during the excursion. Static positions like centric relation or maximal intercuspal position aren’t about this lateral separation, so they don’t describe the disclusion pattern in lateral movement.
