What type of tooth impaction always requires removal of bone and sectioning?

Vertical
Mesioangular
Horizontal
Distoangular

The correct answer is: Horizontal

Horizontal impactions are the most difficult type of impaction to manage surgically as they are positioned completely horizontally against the second molar. Due to the challenging angle and position, removal of bone and sectioning of the tooth is often necessary to successfully extract a horizontally impacted tooth. This process allows for better access and control during the extraction procedure. Vertical impactions (Choice A) involve teeth that are oriented vertically but are unable to erupt properly. Mesioangular (Choice B) and distoangular (Choice D) impactions refer to teeth that are angled towards the front or back of the mouth, respectively. While these types of impactions may require some level of surgical intervention, they do not always necessitate the same level of bone removal and sectioning as horizontal impactions.
