In the context of dental occlusion, the phenomenon involves the relationship and contact between the upper and lower teeth during various functions such as chewing and speaking. The factors that primarily control occlusion include the physical attributes of the teeth themselves, the receptors located in the periodontal membrane, and neuromuscular receptors that contribute to the overall functioning of the masticatory system.

Teeth play a fundamental role in occlusion; their shape, alignment, and size directly influence how they interdigitate with opposing teeth. This anatomical relationship is crucial in determining how forces are distributed during functional activities.

Receptors in the periodontal membrane are essential for providing sensory feedback about the position and tension of the teeth, facilitating adjustments to maintain a harmonious occlusion. These receptors help in the proprioceptive awareness of tooth position and force exertion, which are critical for proper mandibular function.

Neuromuscular receptors also play a vital role as they help regulate muscle function involved in mastication. These receptors provide information about muscle tension and jaw position, allowing for coordinated movement of the jaw in relation to the teeth.

All these components work together to create an intricate system that governs occlusion, indicating that a comprehensive understanding of occlusion cannot be attributed to just one element but involves the
