How are ligature ties placed?

The placement of ligature ties involves looping them under the four extensions of the bracket. This method ensures that the tie securely holds the archwire in place, providing the necessary tension and stability for proper alignment of the teeth during orthodontic treatment. The four extensions, often referred to as "wings," are designed to accommodate the ligature, ensuring a snug fit that prevents any movement of the archwire.

This technique is essential in orthodontics as it directly impacts the effectiveness of the braces. A proper ligature tie placement maintains the correct positioning of the archwire while also facilitating the desired movement of the teeth. Understanding the function and placement of ligature ties is crucial for any dental assistant working in an orthodontic setting.
