How long must a patient typically wear headgear for effective orthodontic changes?

For effective orthodontic changes, patients typically need to wear headgear for 12 to 14 hours each day. This duration is essential because it allows for consistent and adequate force application on the teeth and jaws, which promotes the desired tooth movement and skeletal corrections.

During this time, the headgear exerts forces that help to correct issues such as overbites or underbites, by guiding the growth of the jaw or moving teeth into better alignment. Wearing it for the recommended hours ensures the treatment proceeds at an optimal pace, helping to achieve the best results within a reasonable timeframe.

The other options may suggest insufficient wear time for the intended effects of headgear. For instance, wearing it only 8-10 hours may not provide the necessary force required for dental movement, while wearing it 24 hours could lead to discomfort and potential complications that can arise from excessive use. Similarly, just wearing it during the day would not meet the necessary cumulative hours and could impede progress.
