Which alignment type focuses on correcting anatomical overlap between contacts?

The alignment type that focuses on correcting anatomical overlap between contacts is horizontal alignment. This type of alignment is crucial in dental radiography as it helps ensure that the images capture the correct relationships between teeth, particularly at the points of contact. By adjusting the horizontal alignment, clinicians can minimize the chances of overlapping structures that could obscure diagnostic information, allowing for clearer visualization of the dental anatomy.

In contrast, vertical alignment pertains to adjusting the vertical angle of the x-ray beam, which may help in other situations but does not specifically address the overlap between contacts. Radial alignment and angular alignment involve adjustments based on different geometric principles that do not directly tackle the issue of anatomical overlap in the same way that horizontal alignment does. Thus, the emphasis on correcting anatomical overlaps makes horizontal alignment the correct focus for this context.
