Answer:
When the maxillary first molars require stabilization or distal movement, (3)
a high pull traction on the head gear is used.
Step-by-step explanation:
In orthodontics, the use of headgear is a common practice to address specific tooth movement needs. When dealing with maxillary first molars that require stabilization or distal movement, a high pull traction on the headgear is employed. This technique involves applying forces in the vertical direction, exerting pressure on the upper molars and aiding in their desired movement.
The high pull traction is particularly effective in controlling the position of the maxillary molars and ensuring their proper alignment within the dental arch. Orthodontists carefully assess each patient's case to determine the appropriate type of headgear and traction force needed for optimal results.
Option 3 is correct.
