Mandibular movement patterns in complete denture wearers closely resemble those in individuals with natural dentition because the neuromuscular control of the mandible remains intact regardless of dentition status. Although dentures provide an artificial occlusal surface, the muscles and joints guide mandibular motions similarly, allowing functional movements such as protrusion, retrusion, and lateral excursions. Properly fabricated dentures restore vertical dimension and occlusal plane, enabling physiologic movement patterns to be maintained without significant restriction or randomness. Therefore, mandibular kinematics in denture wearers are fundamentally the same as in those with natural teeth.
