Which of the following is not considered for esthetics when setting maxillary teeth?

When setting maxillary teeth, esthetic considerations are crucial for achieving a natural appearance in dental restorations or prosthetics. The midline, tooth position, and occlusal plane all play significant roles in ensuring that the final arrangement of teeth aligns with the patient's facial features, smile aesthetics, and functional harmony.

The midline helps to create balance in a smile by aligning it with the facial midline, which is important for symmetry. Tooth position affects how individual teeth relate to each other and their overall alignment within the dental arch, influencing the perceived attractiveness and functionality of the dentition. The occlusal plane is vital for achieving proper alignment of the teeth when the mouth is closed, impacting both functional aspects and visual appeal.

In contrast, while arch form does have some influence on the overall dental aesthetic, it does not directly contribute to the immediate visual aspects of each individual tooth's placement or orientation, which are more critical for constructing a pleasing smile. The arch form is more related to the general shape and curvature of the dental arch rather than the finer details necessary for esthetics. Therefore, it is not primarily considered from an esthetic perspective when setting maxillary teeth.
