What does mesial drift refer to?

1. Movement of teeth toward the midline

2. Movement of teeth away from the midline

3. Stability of teeth post-eruption

4. Alignment of teeth with facial features

The correct answer is: Movement of teeth toward the midline

Mesial drift refers to the natural movement of teeth towards the midline of the dental arch. This phenomenon occurs primarily as a result of various factors such as the eruption of adjacent teeth and natural occlusal forces. As teeth erupt and wear down, they tend to shift slightly towards the center of the mouth, which aids in maintaining dental alignment and occlusion. This is important in pediatrics and orthodontics, as understanding mesial drift can help dental professionals predict movement patterns and address alignment issues effectively. In comparison, the other options focus on movements away from the midline or aspects of stability and alignment that do not capture the essence of mesial drift. Stability post-eruption and alignment with facial features are significant but pertain to different processes and considerations in dentistry.
