Which occlusal scheme describes the posterior teeth preventing excessive contact of the anterior teeth?

• A. Mutually Protected Occlusion
• B. Group Function
• C. Bilateral Balanced Occlusion
• D. Anterior Guidance

Answer: (A)

Mutually protected occlusion describes a pattern where the posterior teeth provide the stops in centric occlusion, limiting how much the anterior teeth contact, while the anterior teeth guide the mandible during movement and disclude the posterior teeth in eccentric movements. This arrangement protects the anterior teeth from excessive loads during closing and protects the posterior teeth during excursions by relying on anterior guidance to direct movement. In other schemes, contact patterns aren’t organized this way: group function emphasizes multiple posterior contacts on the working side rather than a protective role for the anterior teeth; bilateral balanced occlusion aims for contacts on both sides across movements; and anterior guidance centers on the anterior teeth guiding the bite and often discluding posterior teeth without the same protective centric stops.
