What do you see on the balancing (non-working) side during mandibular excursive movement?
Show answer and explanation
Correct answer: C. No contact of posterior teeth on the side away from which the mandible is moving
In a properly functioning natural dentition with canine guidance/mutually protected occlusion, the balancing (non-working) side — the side away from which the mandible is moving — should show NO contact of the posterior teeth during excursive movement (this is the principle of disclusion/disocclusion of the balancing side, which protects against damaging lateral forces). Options describing anterior or working-side contact patterns don't describe what should be seen specifically on the balancing side.
