What does cervical pull in E/O anchorage typically accomplish?

Cervical pull in extraoral (E/O) anchorage typically accomplishes distalisation and extrusion of molars, making this the correct answer. This technique involves the use of headgear that exerts force on the molars in a direction that moves them posteriorly while also allowing for slight upward movement (extrusion).

When cervical pull headgear is used, the force is primarily directed towards the back of the mouth, influencing the molar teeth to move distally. This is particularly effective in cases where molars are positioned too far forward, either for correction of an Angle Class II malocclusion or to create space in the arch. The design of the cervical pull headgear optimally supports the movement while effectively maintaining anchorage for the anterior teeth, preventing unwanted movement of those teeth throughout the treatment.

Other options do not correctly represent the primary outcome of cervical pull in E/O anchorage, emphasizing instead movements that are not primarily associated with this method. For instance, intrusion of anterior teeth focuses on moving them deeper into the socket, which cervical pull does not accomplish. Similarly, while advancement of incisors may be a goal of different orthodontic treatments, it is not a direct outcome of this specific technique, nor does it relate to the
