Final answer:
A cervical traction headgear device is used in orthodontics to apply force on the maxillary molars, moving them distally towards the back of the mouth for alignment corrections.
Step-by-step explanation:
The purpose of a cervical traction headgear device is not directly associated with the mandibular movements described. Instead, it's used primarily in orthodontics to correct bite and align the teeth, particularly, it helps in managing the position of the maxillary first molar. When applied, the device exerts force on the maxillary molars, typically to move them in a desired direction to correct an overbite or other dental misalignments.
Based on the provided figures and information regarding the application of force by wires in braces, the closest related action of a cervical traction headgear would be to move the maxillary first molar distally, that is, towards the back of the mouth to correct alignment. This is essential for improved dental health and optimal jaw function.
