The Submentovertex view primarily visualizes the base of the skull and the zygomatic arches, making it ineffective for evaluating maxillary fractures such as Le Fort I. In contrast, the Waters, Lateral cephalometric, and AP views provide clear visualization of the maxillary sinus walls and the horizontal fracture line characteristic of Le Fort I fractures. Accurate imaging of the lower maxilla and alveolar ridge is essential for diagnosis and surgical planning, which the submentovertex view fails to provide. Therefore, the Submentovertex view does not adequately demonstrate a Le Fort I fracture.
