What landmark is used on the face for positioning a maxillary anterior occlusal film?

The bridge of the nose is the correct landmark used for positioning a maxillary anterior occlusal film. This area serves as a reliable reference point because it is centrally located on the face and aligns with the midline, which is crucial for obtaining accurate radiographic images of the maxillary anterior region. Proper positioning is essential for capturing the teeth and surrounding structures effectively.

Using the bridge of the nose helps in angling the film appropriately, ensuring that the X-ray beam is perpendicular to the film plane. This technique minimizes distortion and enhances diagnostic quality.

Other landmarks like the tip of the chin, center of the forehead, or below the eyes, while they might have functional uses in other types of imaging, do not provide the same degree of precision for aligning the occlusal film to capture the maxillary anterior region specifically.
