Which factor should NOT be considered when setting denture teeth?

When setting denture teeth, the primary aim is to ensure that they function well and fit comfortably within the patient's oral environment. Tongue space is an essential consideration for denture aesthetics and function, but it should not directly influence the arrangement of the teeth themselves.

Arch form refers to the shape and contour of the jaw, which is crucial in selecting the appropriate size and arrangement of teeth to ensure a proper fit and occlusion. The midline is significant for dental aesthetics and symmetry, ensuring that the denture appears natural and aligns with the patient's facial features. Tooth position is vital for achieving proper occlusion and functional movement during speech and mastication.

In contrast, while tongue space is important for overall oral function, it does not dictate the positioning of the denture teeth directly. Therefore, it should not be a primary factor when specifically positioning or setting the teeth in a denture.
