Which orientation of 3rd molars is the most difficult to extract?

Vertical
Mesioangular
Distoangular
Horizontal

The correct answer is: Distoangular

The distoangular orientation of 3rd molars is the most difficult to extract. This is because these molars are positioned at an angle where they are leaning towards the back of the mouth, making it more challenging to access and remove them. The vertical orientation (choice A) may also be difficult to extract, as it requires the tooth to be lifted straight up rather than at an angle. The mesioangular orientation (choice B) and horizontal orientation (choice D) may be easier to extract as they do not require as much force or manipulation. However, the distoangular orientation usually requires more skill and precision from the dentist or oral surgeon performing the extraction.
