What is the purpose of wrapping a loop of wire on top of the braces?

The wire wrapped around the top of braces is often referred to as a "ligature wire" or "support nail". Their purpose is to secure and stabilize the braces to ensure that they remain in the correct position and shape on the teeth.

Ligatures or pins enhance the effectiveness and stability of orthodontic treatment by securing the braces in place on the teeth. They are often used in orthodontic treatments that require increased support, such as when rubber bands or other orthodontic appliances are used to pull teeth out of place.

The use of ligature wires or pins can increase the efficiency and effectiveness of orthodontic treatment, helping to align teeth more closely and improve bite and facial appearance. They can also reduce recurrence and rebound after orthodontic treatment, ensuring long-term results.

The process of wrapping ligature wires or supportive nails around braces is selected and manipulated by the doctor according to the patient's specific situation and orthodontic program. Generally speaking, the ligature wire or the supportive nail needs to be replaced periodically to ensure the continuity of its action and effect. Patients also need to follow the doctor's advice and instructions on the proper use and maintenance of braces and orthodontic appliances for optimal treatment results.
