What is the term for the condition when there is maximal stable contact between the occluding surfaces of the maxillary and mandibular teeth?

Centric Occlusion
Occlusal Equilibrium
Maxillary Alignment
Mandibular Closure

The correct answer is: Centric Occlusion

The term that refers to the maximal stable contact between the occluding surfaces of the maxillary and mandibular teeth is centric occlusion. This condition, also known as maximum intercuspation, occurs when the cusps of the molars interdigitate fully, providing the most stable and complete contact between the upper and lower teeth. In this position, the jaw is typically closed and aligned in such a way that the forces of occlusion are evenly distributed among the teeth, which is essential for proper function, stability, and overall oral health. This situation represents an ideal occlusal relationship, minimizing wear and tear on teeth and preventing potential issues such as misalignment or TMJ disorders. Understanding centric occlusion is crucial for dental professionals, as it serves as a foundational reference point for assessing and planning any necessary orthodontic or restorative treatments.
