How do self-ligating brackets impact friction during orthodontic treatment?

Self-ligating brackets are designed to reduce friction between the bracket and archwire during orthodontic treatment. Traditional brackets require elastic or metal ligatures to secure the wire, which can create additional friction due to the tightness and material properties of these ligatures. In contrast, self-ligating brackets utilize a sliding mechanism or door that allows the wire to move freely within the bracket.

This design minimizes the frictional forces acting on the archwire, facilitating more efficient tooth movement. Reduced friction not only enhances the effectiveness of tooth movement but can also lead to shorter treatment times, as the forces applied to the teeth are delivered more smoothly and efficiently. Overall, the key advantage of self-ligating brackets lies in their ability to reduce the friction that would typically hinder the orthodontic process.
