What is the main purpose of ligature ties in orthodontics?

The main purpose of ligature ties in orthodontics is to tie the arch wire to the bracket. This is a crucial function as ligature ties help secure the arch wire within the brackets, allowing for effective application of forces to the teeth. By keeping the arch wire in place, ligature ties facilitate the movement of teeth into the desired positions as part of the orthodontic treatment plan.

In orthodontic practice, when the arch wire is placed in the brackets, it is essential for the wire to remain securely attached. This is where ligature ties come into play, as they wrap around the brackets and hold the wire firmly, ensuring that the forces exerted for tooth movement are transmitted effectively.

The other options do not accurately describe the primary function of ligature ties. Connecting headgear to molar bands involves different types of connectors or attachments, while providing support to the dental arch is more related to the role of the brackets and the arch wire itself. Stabilizing screws in brackets often pertains to specific types of braces and their components, rather than the general function of ligature ties. Overall, the ligature ties' role in tying the arch wire to brackets is fundamental for a successful orthodontic outcome.
