In a Group Function occlusal scheme, which of the following is true?

• A. Multiple posterior teeth share contacts on the working side.
• B. Only the canines contact on the working side.
• C. All posterior teeth contact symmetrically on all movements.
• D. No posterior teeth contact in any movement.

Answer: (C)

In a Group Function occlusal scheme, the focus is on distributing the bite forces across several posterior teeth on the working side during lateral movements rather than concentrating contact on a single tooth. When the mandible moves to a side, multiple posterior teeth on that side come into contact and share the load, helping to balance wear and reduce overload on any one tooth. This pattern keeps the anterior teeth out of the working interference (they proffer disclusion), and the balancing side typically lacks posterior tooth contact. The idea that multiple posterior teeth touch on the working side, rather than a single tooth guiding the movement, is what characterizes group function.
