What is the best indicator for the amount of impaction necessary for a Vertical Maxillary Excess (VME) patient?

The best indicator for the amount of impaction necessary for a patient with Vertical Maxillary Excess (VME) is the maxillary incisor show at rest. This is because the amount of incisor show directly correlates with the vertical facial proportions and the amount of excess maxillary display. In cases of VME, there is often an increased amount of incisor display when the patient is at rest, which can affect both the aesthetic and functional aspects of the occlusion.

By assessing the incisor show, clinicians can determine how much vertical reduction is required to achieve a more balanced facial aesthetic and improve occlusal function. This measurement provides a practical and observable quantification of the excessive maxillary position, guiding surgical intervention planning.

Mandibular incisor show, facial symmetry, and palatal height can provide useful information in the overall assessment of the patient's condition, but they do not specifically address the amount of impaction required as directly as the maxillary incisor show does. Therefore, relying on the maxillary incisor show brings clarity and direct correlation to the treatment planning for VME correction.
