Which of the following will NOT be used in the determination of vertical dimension?

The determination of vertical dimension in dentistry is a critical aspect of assessing and planning dental prosthetics, as it influences the overall function and aesthetics of the patient's bite. The process typically involves various measurements and evaluations that are influenced by different physiological and functional factors.

Gothic arch tracing is a specific technique used primarily in recording the movements of the mandible. It is typically employed to observe jaw relations and range of motion rather than to assess vertical dimension directly. Although it provides important information regarding jaw movements, it does not contribute to determining the vertical height at which the teeth should occlude.

In contrast, the other elements mentioned play significant roles in assessing vertical dimension. Aesthetic considerations involve how the teeth align and the overall facial profile, which can influence the vertical dimension indirectly. Phonetics pertains to how sound production (e.g., speech) is affected by the positioning of the dental arch, which can also help define the correct vertical dimension. Swallowing is a natural function that reflects how teeth are positioned when a person is at rest and engaging in normal activities, thus helping in establishing a functional vertical dimension for the patient.

By recognizing the specific functions and contributions of each factor, it becomes clear why gothic arch tracing is less relevant in determining the vertical dimension
