Which type of wire is strong enough to help re-rotate an anterior tooth?

1. Nickel-titanium wire

2. Stainless steel wire

3. Ortho wire

4. Braided wire

The correct answer is: Braided wire

The strongest type of wire for re-rotating an anterior tooth is braided wire. Braided wire is specifically designed for high strength and flexibility, making it ideal for applying significant force to the teeth while still allowing for adequate movement. This strength is crucial when attempting to reposition teeth, particularly in cases where they have undergone severe rotation. The composition of braided wire enhances its resilience and allows it to withstand the rigors of orthodontic adjustments without losing its shape or effectiveness. Thus, when it comes to achieving effective tooth movement, such as re-rotating anterior teeth, braided wire provides the necessary strength to achieve these goals while also maintaining a level of comfort for the patient. Other types of wire, while useful in various situations, may not provide the same combination of strength and flexibility required for this specific task. For example, nickel-titanium wire is known for its shape memory properties, which are beneficial for consistent light forces over time, but may not generate the same level of force needed for re-rotation. Stainless steel wire is strong and rigid, which is suitable for certain movements but can be less forgiving and less flexible. Ortho wire is a broad term that encompasses different types, but without specifying the material or design, it does not equate
