In mutually protected occlusion, which teeth protect the anterior teeth at intercuspal position?

• A. Anterior teeth protect posterior teeth
• B. Both protect equally
• C. No protection at intercuspal
• D. Posterior teeth protect anterior teeth

Answer: (D)

In mutually protected occlusion, the back teeth take the brunt in the intercuspal (maximum intercuspation) position while the front teeth take on a guiding role during movements. The posterior teeth provide the main occlusal support and absorb the forces in centric position, thereby protecting the anterior teeth from heavy loading. The anterior teeth then act as guides during excursions, helping disclude the posterior teeth and prevent damage from excessive posterior contacts. So, the posterior teeth protect the anterior teeth at intercuspal position.
