Orthodontic Assistant Practice Exam

What is a common cause for needing to use a headgear?

1. To correct overbite

2. To correct crossbite

3. To maintain molar position

4. To assist with space closure

The correct answer is: To maintain molar position

The correct choice highlights the utility of headgear in orthodontics, particularly for maintaining the position of molars during treatment. Headgear is often employed to stabilize the molars and prevent them from drifting while other adjustments or tooth movements occur. This is particularly important in growing children, where the teeth and bones are still developing. By anchoring the molars, headgear helps guide the growth of the jaw and ensures that the molars remain aligned, which is crucial for the overall effectiveness of the orthodontic treatment. While headgear can indirectly affect overbites and assist with space closure, its primary and most recognized purpose is indeed the stabilization of molar position. Its role in correcting crossbites may be more relevant in specific types of treatment but is not its primary function. Understanding this function can help in recognizing when headgear should be prescribed in an orthodontic care plan, emphasizing the importance of maintaining molar positions throughout treatment.
