Orthodontic Assistant Practice Exam

Where should the headgear wire be placed?

1. Mandibular tube

2. Maxillary tube

3. Palatine area

4. Labial area

The correct answer is: Maxillary tube

The headgear wire should be placed in the maxillary tube because it is designed to exert a corrective force on the upper teeth and the overall alignment of the maxillary arch. Headgear typically connects to the upper molars through the maxillary tubes to effectively control the growth of the upper jaw and to help in the repositioning of the teeth. This placement allows for proper distribution of the forces generated by the headgear, aiding in the desired orthodontic movement. In contrast, placing the headgear wire in other areas, such as the mandibular tube, palatine area, or labial area, would not serve the intended purpose of the headgear, which is specifically aimed at the maxillary position. The mandibular tube is connected to the lower arch, which would be irrelevant for maxillary corrections. The palatine area refers to the roof of the mouth, and while it has its own orthodontic applications, it does not provide the same effective anchorage for headgear. Similarly, the labial area is the front surface of the teeth and does not offer the structural support needed for the headgear to work effectively on the maxillary arch.
