The presence of each of the following conditions may indicate using the bisecting technique instead of the paralleling technique except one. Which one is the exception?

A) A class II malocclusion
B) An edentulous region
C) A large palatal or mandibular tori
D) A very low or shallow palatal vault

A
Explanation: A) An advantage of the bisecting technique is its ease of use with patients who have small mouths, very low or shallow palatal vaults or large tori, an exaggerated gag reflex, and in edentulous regions. Malocclusion may require addition radiographs to clearly image all adjacent contact points but is not a factor in determining which technique to apply.
