The primary importance of ligature wire lies in its role in securing the archwire within the brackets of an orthodontic appliance. This function is critical because it ensures that the archwire remains in the correct position to effectively guide the movement of the teeth. When ligature wire is properly placed around brackets, it maintains the connection between the archwire and the brackets, allowing for optimal force delivery to the teeth during treatment.

While stabilizing brackets and aiding in tooth movement are important aspects of orthodontics, the specific function of ligature wire is directly related to holding the archwire in place. The secure attachment provided by ligature wire is essential for the overall effectiveness of the orthodontic treatment, as it helps facilitate the desired movements of the teeth by maintaining the integrity of the archwire system. Additionally, the connection of elastics, while a task that may involve ligature wire, is not its primary purpose, as there are other components designed specifically for that function.
