Which factor is not directly linked to anterior guidance?

Anterior guidance refers to the relationship and movement concerning the anterior teeth during functional movements of the jaw, particularly during lateral and protrusive excursions. The primary function of anterior guidance is to help direct the occlusal relationship and provide a pathway for the lower jaw to move efficiently and comfortably.

Condylar inclination relates to the angle at which the condyle moves as the jaw opens and closes, affecting how teeth interdigitate during movement. Similarly, both vertical and horizontal overlaps of the anterior teeth play crucial roles in establishing anterior guidance, as they determine how the anterior teeth contact during various movements. Vertical overlap helps in discluding posterior teeth when the jaw moves forward, while horizontal overlap influences the lateral motion.

In contrast, the notion of posterior teeth contacting more heavily does not directly relate to the principles of anterior guidance. While this can impact overall occlusion and function, it does not directly influence the mechanics of how the anterior teeth guide the jaw during movement. Therefore, this factor is more about posterior teeth than the specific anterior guidance dynamics that are crucial in occlusion.
